== Running Cumulus MX ==
# Make sure your weather station (and any extra sensors) is connected to the device on which you have installed Cumulus MX, before you try to run Cumulus MX.
# Start '''Cumulus MX engine''' (command to do this varies between operating systems, so see sub-heading for your device below
# Start '''Admin Interface''', it runs in a browser, by default on port 8998, see [[#User_Interface|section]] below.
If you are running MX for the first time, without a configuration file (none is included in download package), see [[Cumulus.ini#Cumulus_MX|here]] for screen shots and instructions.
'''The software currently (this is early 2020) called .NET was originally for all operating systems, but Microsoft then decided to restrict it to just Windows, mostly to encourage greater dominance by Microsoft software and hardware. Mono was then born based on .NET to work with all operating systems, Mono subsequently changed independently from .NET. More recently  Microsoft launched an alternative called .NET Core that took out of .NET the parts that were Windows specific. Perhaps confusingly, in November 2020, there will be change around of names, and the multi-operating system .NET Core product will take over the .NET name. I don't pretend to understand the technical details, but the impression I get is that the new .NET in November will be similar to Mono, so apps designed for that will still work, but apps using .NET to make code designed for windows will stop working'''
=== Requirements for running on Windows ===
To run MX on Windows, you need .Net version of at least 4.5.2 installed. This is only available for  Vista SP2, Windows 7 SP1, Windows 8, Windows 8.1.
For Windows 10 you need version 4.8 or later, this should already be installed by your windows update feature.  The .Net download for version 4.8 should be here https://dotnet.microsoft.com/download/dotnet-framework/net48.
Cumulus MX initiates a web server, to do this it may need administrative access, consequently to avoid having to run MX as an administrator you can issue a command that allows all users to bind to port 8998 which is the web server it initiates (this is used for the Cumulus MX user interface). Note that if you plan to change the interface port by using the port parameter in your launch of MX, you should change the 8998 to whatever port you are planning on using. To enter the command, first open a command window as administrator. One way to do this is to right click the windows symbol at the start of the windows task bar. The option to choose there (on windows 10) is '''Windows PowerShell (admin)''', but an option called '''Command Prompt (Administrator)''' will also work. Once that opens a new window type:
<pre>
netsh http add urlacl url=http://*:8998/ user=\users
</pre>
You only need to do that once. After than you can initiate MX from any user, you don't need to run as administrator.
Talking about command windows, if you want to check that the port is open for listening (when MX is running, the port is used for the administrative interface) type <tt>netstat -an | findstr 8998</tt> into the command window.
After you have done this you can run CumulusMX.exe normally without Administrator rights and therefore you can create a short-cut to run MX when your PC starts (put your user name where I have put ...), the shortcut should point to T:\CumulusMX\CumulusMX.exe (where T is used here only to denote the drive on which you have installed MX as it does not need to be the same as where your operating system is):
C:\Users\...\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup\CumulusMX.exe
With this you might want to right click on that shortcut, select properties, then you can set the starting position for the command window, the colours and font it will use, and even choose to start minimised, amongst many other selections.
Look at your hub or router (this should have come with instructions on how to do this in your browser) and on one screen it should show what devices are connected to your LAN and wifi. Look for the IPv4 address (w.x.y.z) of the device you have installed MX on, for example 192.168.1.64. Then give your Computer a fixed address  for MX user interface by finding the network card via Network and Sharing Centre (Control Panel), click on Change Adapter Settings, then Right click on Ethernet or WiFi Adapter, select Properties and in the window that opens right click on Internet Protocol Version 4 (TCP/IP 4), and select properties and on that pop up screen tell the computer to "use the following IP address and fill it out with a subnet mask of 255.255.255.0 and gateway address between 192.168.1.1 and 192.168.1.254 (depending on the address of your hub/router).
==== Setting up for either manual or automatic running ====
There are 3 ways on Windows to create a way to run MX
#Create a shortcut on your desktop (and/or the taskbar) for the '''CumulusMX.exe''' executable <tt>cmd.exe /C start CumulusMX C:\CumulusMX\CumulusMX.exe -debug</tt>, the "-debug" is ''optional'', it starts the logging in debugging mode so the log created in MXDiags folder has more information. There are other optional parameters all listed later.
#*In that shortcut define the path where the executable is located as the path to start in.
#* '''Remember, if you have not done the <tt>''netsh http add urlacl url=http://*:8998/ user=\users''</tt> command mentioned above, you must run as administrator.'''
#* Add any of the parameters that can be used with the executable, as listed later, such as specifying a different port for the admin interface , or starting with debugging.
#*Choose whether to start as minimised or as a command window
#*You can also choose text colour (foreground) and background colour, you can choose where the window appears (so if you have two monitors you can choose which one it appears on), and how big that window is. There is a forum post by water01 about this.
#*Now you can click the shortcut to start the engine
#OR place the shortcut as defined above in the start up folder for the user account so MX automatically starts when you connect/log in (see a later section for how to find that start up folder).
# OR declare a task in the scheduler to start MX; in the '''Actions''' tab fill in fields as follows (the other tabs should be obvious):
#**'''Action''' <tt>Start a program</tt> from drop-down
#**'''Program/script''' <tt>cmd.exe</tt> (this is standard Windows environment to run something)
#**'''Add arguments''' <tt>/C start Start_MX \CumulusMX\CumulusMX.exe -debug -port=nnnn</tt> (the "/C" means this task will close once it has started the task, the "Start_MX" is how the task will be labelled as it is running, the next argument "\CumulusMX\CumulusMX.exe" actually starts the executable and it does not need a drive prefix as that is in next box.
#**Note in this example I have included next two optional parameters that can be used after the .exe call in that same box, here '''-debug''' (only include if you want full debugging logging) and '''-port=nnnn''' where nnnn is the port to be used for admin interface (only include if want to change from default 8998),
#** all optional parameters are listed later
#**'''Start in''' <tt>\CumulusMX</tt> (include a drive specifier if necessary)
==== Each time you want to run Cumulus MX on Windows: ====
#First '''start the engine''' in one of the 3 ways from last sub-section
# Next '''start the admin interface''', it does not need to run all the time, but only when you need it (when you first use MX you will need it to access the settings where you tell MX what type of station you have and what units you want to use, and set various timing options), it normally runs on port 8998 (to vary that there is a '''-port''' parameter that is followed by required port and that port parameter has to be entered every time you start MX if you are not using the default port).
Try '''start /min C:\Cumulus\CumulusMX.exe''' to run MX as a minimised package (although in Windows you can change the properties of the shortcut you use to start minimised).
==== Stopping Cumulus MX on Windows pc ====
The recommended way is to click into the command window in which MX is running, ''hold down Control key'' and press '''C'''. It is normal for there to be a short wait, then a message "Cumulus Terminating" and then after another short wait, it will say "Cumulus Stopped" and immediately after that the command window  will close.
Some people, click in the task bar and select close, or click the '''X''' button on top right of command window. Although these are not official advice, they do seem to work.
There are packages that can be programmed to send a control C to a running task, and to not continue until the task window has closed. Remember to also program in a subsequent delay in that package, to make sure the package waits for MX to close, or do a check that MX has released all the files it might need to update.
''You should not'' issue a '''TASKKILL''' instruction, as that will prevent MX correctly writing out to all the files it should update on exit. Consequently, it will not restart correctly and may actually lose settings and data.
=== Requirements for running on Linux and OS X ===
You will need to install the '''Mono-complete''' runtime (the latest version of Mono should work with all functionality of latest MX in all locales). Mark Crossley says "There shouldn't be any outstanding issues with Mono, afaik they are all resolved - except for the Moon image rotation in the southern hemisphere which does not work with Mono 6.0 thru to the latest 6.8.0, only version 5.x works correctly atm for System Drawing."
* For OS X, you can download this here - http://www.mono-project.com/download/.
* How you install on Linux depends on the flavour of Linux you are running. There are download links for Linux at the same URL, but it is often easier to use a package manager, which will download and install it automatically.
**For example, in 'Raspbian' on the Raspberry Pi, you can install mono with these commands:
<pre>
sudo apt-get update
sudo apt-get install mono-complete
</pre> or
<pre>sudo apt update && sudo apt upgrade
sudo apt install mono-complete</pre>
Make sure that you have the '''mono-complete''' package installed.
The "sudo" prefix gives the command 'root' privileges, that allows administrative commands like update and install to run.
==== To actually run MX ====
Open a terminal window, change to the Cumulus MX directory, and then type:
<pre>sudo mono CumulusMX.exe</pre>
Next start the administrative interface, basically same as described for Windows above. More information on admin interface later.
==== Other issues  ====
There are lots of topics in the MX sub-forum about a multitude of issues about commands to use to install and check mono, how to stop MX and differences between different devices (including Mac) and different Linux versions. At the moment, there seems to be some uncertainty, and consequently, I have not attempted to include/summarise all the material I have found.
'''APPEAL''' - Please could any readers who have experience of running MX in a Linux or Mac environment please consider writing advice into this article. I want it to be a comprehensive accurate article.
==== Notes by ExperiMentor (in Switzerland) ====
These comprehensive notes describe how to install Cumulus MX on a Pi Zero, using a PC to do some of the work:
'''Buy equipment'''
* Raspberry Pi Zero W
** A faster Pi is NOT needed for running Cumulus. Pi Zero W has WiFi and one USB port which is all that is needed for headless running.
** Using a faster Pi might speed parts of the installation process, but are overkill for actual ‘production’ running. A faster Pi will work fine though if you have one going spare and don't mind the extra power use.
** Case if desired
* Micro SD card eg 16 GB, decent quality. Adapter if needed to put Micro SD card in PC
* OTG cable (micro USB plug to standard USB socket) to connect a USB weather station to Raspberry Pi [you may have got one free with a mobile phone or tablet] if it's a USB weather station. Not needed if you have a WiFi or ethernet weather station. An Ethernet weather station will need connected to your router, not the Pi.
* Suitable Micro USB power supply (it does not need to be a high power 2.5A version for Pi Zero W with only the weather station attached; it will be powered on 24/7, so a low power consumption ‘switched mode’ type is preferred – ie one that does not become warm when plugged in with nothing attached. You may have a suitable one from a mobile phone.
'''
Download useful PC software and install on your PC'''
These instructions are for a Windows PC. Steps would be similar on a Mac, but programs and details would differ. Should also be possible with an Android tablet.
* SD Formatter (the Windows Format facility will NOT do)
** https://www.sdcard.org/downloads/formatter_4/index.html
* balenaEtcher (for unzipping and burning images to SD cards) [Previously named 'Etcher'] <tt>https://etcher.io/</tt>
* Win32DiskImager (for backup & restore of SD card images) <tt>https://sourceforge.net/projects/win32diskimager/</tt>
* PuTTY (an SSH client for Windows) <tt>https://www.putty.org/</tt>
* FileZilla (an FTP file transfer program for Windows) <tt>https://filezilla-project.org/download.php</tt>
'''Download Raspbian Pi Operating System'''
* Save it on your PC, from https://www.raspberrypi.org/downloads/raspbian/
* "RaspBIAN Buster Lite" is probably OK, but other than small file size it offers no advantage over installing the full version of RaspBIAN Buster. These instructions are being tested using "Raspbian Buster with desktop and recommended software", the largest of all, which could allow you to do other things more easily.
* Just click on “Download Zip” (torrent might be faster if you have the ability, but not worth installing just for this)
* Do not unzip it
* These instructions have been tested with kernel version 4.14, released 18 April 2018 and with kernel version 4.14, released 13 November 2018 [March 2019] and kernel version 4.19 released 10 July 2019
'''Install Pi Operating System onto Micro SD card'''
''Format the SD card''
* Put Micro SD card in PC (use adapter if needed)
** If re-using a previous Pi SD card, click ‘Cancel’ on the warning about needing to format the card
* Run SD Card Formatter (click Yes to ‘Allow to make changes to your device’).
** Need to use this program rather than the Format tool in File Explorer, because Pi SD cards end up with a very small ‘Windows accessible’ partition and a large partition containing Linux. SD Card Formatter allows reclaim of the large partition.
* Your SD card should automatically populate in the ‘Drive’ box. In case you have another SD card in your PC, ensure the correct card is selected!
* Click ‘Format’ and check and accept the Warning messages
'''Copy the Pi Raspbian Operating System onto the card'''
* Run '''balenaEtcher''' on your PC
* Click ‘Select Image’ and choose the ‘Raspbian Buster’ operating system zip file that was downloaded earlier
* SD card should be automatically populated. In case you have another SD card in your PC, ensure the correct card is selected!
* Click ‘Flash!’. The operating system will be copied to the card. This takes about 10 minutes, followed by another 8 minutes to ‘Verify’
* Cancel any messages about needing to Format the card - they are just indicating that Etcher has installed the partition that cannot be read by Windows
* On completion, the card is ‘ejected’ from the PC. Physically remove it and then straight away reinsert it so that the content can be viewed in File Explorer
* TWO drives will now be visible for the SD card. You will likely see a warning that one of the drives needs to be formatted before it can be used. ‘Cancel’ that warning and ignore that drive.
* View the other drive, which is named ‘boot’ in File Explorer
* On the View tab, ensure the ‘File Name extensions’ is ticked
* Right click and select ‘New’, ‘Text document’. Change its name to SSH (deleting the .txt extension; you need to make an empty file called SSH not SSH.txt). Click ‘Yes’ to ‘Are you sure you want to change the extension?’
* Right click and select ‘New’, ‘Text document’. Change its name to wpa_supplicant.conf (deleting the .txt extension; you need to make a file called wpa_supplicant.conf not wpa_supplicant.conf.txt). Click ‘Yes’ to ‘Are you sure you want to change the extension?’
* Right click on this new file and select ‘Open with Notepad’ or ‘Open with …’ then select Notepad. Enter the following content exactly as below (copy and paste) then edit your country code (if needed), WiFi network’s SSID and password: NOTE: Change GB as needed to be the code for your country. The quote marks should appear in the file, that is ssid="YourNetwork" not ssid=YourNetwork . Same for psk.
<pre>ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
country=GB
network={
    ssid="YourNetwork"
    psk="YourNetworkPassword"
    key_mgmt=WPA-PSK
}</pre>
* Not essential, but I like to keep copies of both those files for future use. They can be on the SD card with different names eg ‘SSH - Copy’ and ‘wpa_supplicant.conf - Copy’ as well as on your PC
* The function of these 2 files is to connect your Raspberry Pi to your network as soon as it boots, and allows you to connect to and control it from your PC by SSH using PuTTY. This avoids needing to connect a keyboard, mouse and monitor to the Raspberry Pi. It is particularly useful for Pi Zero W (or Pi Zero) which hasn’t got enough USB connections and no Ethernet (wired network) connection. This is called ‘Headless operation’.
* Right click on the ‘boot’ SD card in left pane of File Explorer and ‘Eject’ it safely.
'''Setting up the Raspberry Pi'''
* With nothing plugged into the Raspberry Pi, take the Micro SD card from your PC and put it in the Pi.
* In a later step, you will need to find out the Raspberry Pi’s IP address by looking at your network router’s web interface. I can’t help you with doing that. If you don’t know how to, an alternative is to connect a keyboard, mouse and monitor to the Raspberry Pi at this stage
* Plug the power supply into the Raspberry Pi. It will boot up (note flashing red and/or green LEDs depending on model).
* On your PC, log into your network router’s web interface and identify the Pi’s IP address, which will be in the form xxx.xxx.xxx.xxx, for example 192.168.1.123
** NOTE: If you will be switching from a faster “build” Raspberry Pi to a “production” Raspberry Pi Zero W, the IP address will change, so you’ll need to repeat this step later
** While in your network router for the ‘production’ Pi you will be using, set up some port forwarding that will be needed later.
** Forward port 8998 to your Pi’s IP address for TCP protocol if you want to be able to access the Cumulus web interface from the external internet (this brings potential security risk though). [Forwarding port 8002 as well was previously needed].
* Start PuTTY on your PC. In the box for ‘Host Name or IP address’, enter the Pi’s IP address from above. In the adjacent ‘Port’ box, enter 22. Connection type should be SSH. Click ‘Open’.
* A window opens. The first time you do this you will probably see a long message asking to confirm it is OK to connect to a not-previously-known device. Click ‘Yes’.
* Login to the Pi. Username is pi [lower case] and password is raspberry [lower case]
* You will see a warning that SSH is enabled but the password has not been changed, which is a security risk. We will change the password in a moment
* Type
<pre>sudo raspi-config</pre>
* Note, to copy from here (usually need to do 1 line at a time), select it then CTRL-C. To paste into the PuTTY window, right click.
* As needed, adjust the following settings:
** Change the password to something you will remember. Leaving it at raspberry is a serious security risk – exposes your whole network to hackers
** In Network Options,
**#change the name of your pi to ‘Cumulus’ or something you prefer
**# WiFi network and password have already been set by the wpa-supplicant.conf file added earlier
** In Boot Options, Desktop / CLI, select ‘Console Autologin’
** In Localisation Options,
**# change ‘Locale’ if you need something different to en_GB.UTF-8. [Changing this takes quite a while on a slow Pi]. [As of Sep/Oct 2019, there is some kind of incompatibility between RaspBIAN Buster, mono v6.0.0.314 and locales other that en_GB - so unless you NEED another locale, it would be better to leave it as en_GB. The alternative is to force load an older version of Mono, for example v5.18]
**# Change Timezone.
**# Change Keyboard Layout if needed
**# WiFi country has already been set by the wpa-supplicant.conf file added earlier
** In Interfacing options, SSH server has already been set to be enabled by the empty SSH file added earlier
** Select ‘Finish’. There is no need to reboot at this stage. But until you do, you will see messages "sudo: unable to resolve host raspberrypi", but these can be safely ignored (it's just because you renamed the Pi - will disappear after next reboot)
In the steps below, you will need to press '''y''' to agree to proceed at various times
If you have been building the Micro SD card on a fast Pi, now is the time to switch to the 'production' Pi, for which a slower Pi Zero W is more than adequate.
Shut down the Raspberry Pi safely.
<pre>sudo halt</pre>
'''Move the micro SD card to the Pi Zero W'''.
Power on the Pi Zero W. Your SSH (PuTTY) session will close out and you'll need to reconnect after the Pi has rebooted. Use username pi and the new password you chose earlier.
'''Add the ‘Mono’ package'''
* Simplification: Mono is a package which allows programs to be written cross-platform so that they will run on Linux (including Raspberry Pi), Windows and Mac OS, similar to the Windows ‘.NET Framework’.
* The previous anomaly with the USB library not working with later versions of mono, affecting Fine Offset stations and the later Oregon Scientific stations (WMR88/100/200 etc) has been fixed (''in CumulusMX build 3044 onwards'') and these and other stations should now be fine with later/current versions of mono. I am currently using a Fine Offset with mono v5.18
* Process is to install a security certificate, add the mono server to the list of software sources [sources.list] that the Pi searches, then install the mono-complete package:
<pre>sudo apt install apt-transport-https dirmngr gnupg ca-certificates
sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 3FA7E0328081BFF6A14DA29AA6A19B38D3D831EF
echo "deb https://download.mono-project.com/repo/debian stable-raspbianbuster main" | sudo tee /etc/apt/sources.list.d/mono-official-stable.list
sudo apt update
sudo apt-get update && sudo apt-get upgrade
sudo apt-get install -y mono-complete
sudo apt autoremove</pre>
At the time of writing (''18 Sep 2019''), this gets Mono v6.0.0.334, which works with Buster (RaspBIAN 10). However, there have been reports of incompatabilities which require use of an older version of Mono. These may have now been fixed, or alternatively may be related to use of locales other than en_GB.UTF-8 . Please see other threads in Support Forum for discussions.
NOTE: ''29 Feb 2020'': added '''-y''' into the line '''sudo apt-get install -y mono-complete''' . This makes the install bypass the usual 'Continue Y/n?' prompt¨which was causing strange problems for some, e.g. worked if just pressed 'Enter' to accept default 'Y', but aborted installation if pressed 'Y Enter'. Bizarre.
'''
Reboot your Raspberry Pi'''
This would be a reasonable time to reboot your Pi:
<pre>sudo reboot</pre>
Your SSH (PuTTY) session will close out and you'll need to reconnect after the Pi has rebooted. Use username pi and the new password you chose earlier.
'''
Install Cumulus MX on the Raspberry Pi'''
Download it [[Software|from here]] to your PC, unzip on your PC which makes a directory named CumulusMX. Remember where that directory is located then on PC run FileZilla
# In the ‘Host’ box, enter the Raspberry Pi’s IP address eg 192.168.1.123
# In Username, enter pi
# In Password enter your pi’s password
# In Port, enter 22
# Click ‘Quickconnect’. Raspberry Pi’s directory structure appears on the right and your PC’s directory structure is on the left.
# In the LEFT window, navigate to where you unzipped the download of Cumulus MX earlier. Ensure can see the folder name ‘CumulusMX’ in the lower left window
# In the RIGHT window, ensure that the folder /home/pi is shown (see top right window; contents in bottom right window include .cache, .config etc)
# Drag the folder ‘CumulusMX’ to an empty area in the lower right window (not onto one of the existing directories). Watch progress as this copies the whole CumulusMX folder and contents to directory ~/CumulusMX on the Pi
# Close FileZilla
'''On Raspberry Pi PuTTY window:'''
<pre>sudo halt</pre>
Plug your USB weather station into the Raspberry Pi – USB cable into the OTG connector (probably via an adaptor lead) if using Raspberry Pi Zero W.
If you have an ethernet or WiFi linked weather station then you won't need to do this - I don't have one so I don't know exact details. Steve below says you need to enter the IP address during Cumulus setup, but then also adjust a disconnect period if you are also using Weatherlink software.
'''Running Cumulus'''
On PC, run PuTTY again and log in to the Pi as before (note you can save the IP address between sessions)
<pre>cd ~/CumulusMX
sudo mono CumulusMX.exe</pre>
The next thing you will want to do is access Cumulus via its '''user interface''' from your PC, so that you can update the '''settings'''. Using the IP address for your Pi, in your internet browser, enter: 192.168.y.z:8998 (where y and z are numbers you will need to find from seeing how your router connects to your Pi. You’ll first see a dashboard page, then can access the Settings menu.
To make Cumulus run each time the Pi is rebooted (and force reboot in the early hours each day)
On the Pi, type:
<pre>sudo crontab -e</pre>
On first run select the text editor you prefer (defaults to #1, nano, the easiest)
Then add the following lines at the end of the file:
<pre># Start Cumulus as background task 30s after reboot (delay to allow WiFi to startup)
@reboot (sleep 30;cd /home/pi/CumulusMX;sudo mono CumulusMX.exe) &
# Reboot each day at 0253
53 02 * * * sudo reboot</pre>
'''To stop the Pi and restart it without CumulusMX running'''
(eg you need to do that if upgrading the CumulusMX version) type the following
<pre>sudo crontab -e</pre>
'''edit to put a # at the start of the line''' "@reboot..."
Ctrl-X to save the change to crontab and reboot using
<pre>sudo reboot</pre>
When your pi restarts, CumulusMX will no longer be running. You can then do your version upgrade or other task.
To revert to normal auto-running of CumulusMX, go through the same again, but this time edit crontab to remove the # from the start of the line "@reboot...". Save changes and reboot - CumulusMX will be running.
Updating a version of CumulusMX is easily done as follows:
1. Stop CumulusMX running (it locks files while it is running)
2. Install the updated CumulusMX version into a new directory - I call mine CumulusMX3xyz (where xyz are the last 3 digits of the build number) so that I can easily see which build it is
3. copy the following from the old CumulusMX directory to the new CumulusMX3xyz directory:
- your CumulusMX/Cumulus.ini file
- your CumulusMX/data directory
- your CumulusMX/twitter.txt file (if you have personalised it)
- your CumulusMX/web directory (if you have personalised any web files)
4. Change your startup instruction to use the version in the new directory eg cd /home/pi/CumulusMX3050;sudo mono CumulusMX.exe
With that method you can easily revert back to the old version if something has gone wrong. If all is well, you can delete the old directory after a few days/weeks/months/if you need the space.
'''Updating mono version'''
*First, stop CumulusMX as above by editing crontab.
*Then remove the present version of mono:
<pre>sudo apt-get purge libmono* cli-common mono-runtime
sudo apt-get autoremove</pre>
*Then install the new version
<pre>sudo apt-get install mono-complete</pre>
*Finally re-enable auto running by editing crontab to remove the # and finally
<pre>sudo reboot</pre>

=== Notes by Steve Loft ===
''please note these notes ARE now obsolete, library routines have changed a lot since this was written in 2014''
**If you have a Raspberry Pi 2, there is a later version of Mono available, which you may find works better that the one in the standard distribution, particularly if you use decimal commas. Mono 3.2.8 (which is the default in some Linux distributions) will not work if you use commas for decimals, as in some countries.
**On Linux you will need library '''libudev.so.0''' which may not be installed by default. Installing '''package libudev0''' may resolve this. There may be issues if you are using a 64-bit version of Linux. I'm not sure what the resolution is at the moment, if this is the case.
You need to specify something like '''/dev/ttyUSB0''' for the connection for your weather station. This is set in the "station settings" and stored in the [[Cumulus.ini#station|ComportName attribute]] in Cumulus.ini configuration file.
In some builds of MX you have to run as "root", there are ways of giving "root" like permissions when running MX as another user, see forum for details until this section has been updated.
