We have created an customised version of the Raspberry Pi Lite image with Cumulus MX pre-installed and ready to go.
This is designed to be what is called a "headless" installation, that is
=== Pre-Installation Steps ===
You
* A suitable SD card for your Raspberry Pi
:A minimum size of 16GB is recommended. Be sure to buy a good quality card.
:You can use an SSD instead if preferred [with the minor complication that in a later step you will need non-WiFi access to the Raspberry Pi (keyboard and monitor, or SSH over ethernet) as you cannot enter the WiFi details from a Windows PC to the linux SSD due to the different file system used]
* An image installer to copy the image file to the SD card
:The [https://www.raspberrypi.org/documentation/installation/installing-images/ Raspberry Pi site] has a list of suitable software for your operating system. Scroll down to "Writing the image".<br />
: This guide
* The image file to install
:Download the latest image file from
* An SSH terminal program to configure your Raspberry Pi
: For Windows we recommend using [https://www.chiark.greenend.org.uk/~sgtatham/putty/latest.html PuTTY]
* Insert your blank SD card into your computer - if not blank whatever is on the card will be erased.
* Start Raspberry Pi Imager
:* Click the CHOOSE OS button, scroll down to the bottom of the list and select '''Use custom'''
:*; [[File:PiImager-02.png|none]]
:* Browse to the location of the OS Image zip file you downloaded -
:* Click CHOOSE SD CARD, and select the SD card from the Device dropdown - check you have the correct drive selected!
:*; [[File:PiImager-04.png|none]]
::* Set the ssid to match your WiFi id
::* Set the psk to your WiFi password
:* Save the file, and then rename it to '''wpa_supplicant.conf''' - i.e. remove the .txt
* Eject the SD card from your computer.
=== First Boot ===
* Start your browser and see if you can connect to this URL: '''<nowiki>http://cumulusmx:8998</nowiki>'''
:* If you can great - you should now see the Cumulus MX console
:* If not, then you will have to find out the Raspberry Pi's IP address from your router. Then try connecting to this URL: '''http://<ip_address>:8998''' (example: '''<nowiki>http://192.168.1.123:8998</nowiki>''' where the numbers before :8998 are those for YOUR Raspberry Pi from YOUR router). It just depends on your router whether it allows use of the name (cumulusmx) or requires the IP address.
=== Verify your SSH Connection ===
* Fire up your SSH Client - we use PuTTY here
:* Enter the hostname as "cumulusmx", and check the protocol is set to SSH. Then open the connection.<br />
: (
:*; [[File:PuTTY-01.png|none]]
* You will have the accept the SSH key the first time you connect
Retype new password:
passwd: password updated successfully</nowiki>
* It's a good idea to check/configure your RPi for your locale and timezone settings. The default is for en_UK UTF-8 locale and GMT timezone. Use '''sudo raspi-config''' 5. Localization Options, L1 Locale (select en_US ISO-8851-1 for USA if needed) and L2 Timezone (select the appropriate timezone), then '''sudo reboot''' if needed to engage the new settings.
* Check the status of the Cumulus MX service with the command '''sudo systemctl status cumulusmx'''<br />
: You will get some information back, the important bit to note is the line starting '''Active:''', it should say '''active (running)'''
* You can leave the SSH session open, you will need it again soon...
=== Configure Cumulus MX ===
Now it is time to configure Cumulus MX for your station.
* Start your browser and connect to the same URL as before - '''<nowiki>http://cumulusmx:8998</nowiki>''' or '''http://<ip_address>:8998'''
* From the menu select '''Settings | Station Settings''', then follow
* Once your have completed all the settings for for station, and successfully saved them, Cumulus MX will need to be restarted.
* Back in your SSH session, send the command '''sudo systemctl stop cumulusmx''', this stops the Cumulus MX service.
* Wait a few seconds, then enter the command '''sudo systemctl start cumulusmx''', this starts the Cumulus MX service again.
* Back to your browser and check that URL - '''<nowiki>http://cumulusmx:8998</nowiki>''' or '''http://<ip_address>:8998''' - again. If all is well, the default dashboard page should start showing the data from your weather station.
:* If it does, congratulations, you have successfully started recording your weather data
:* If it doesn't, then check back over this process carefully for any mistakes or omissions you may have made.
:* If you cannot resolve the problem, then ask for [https://cumulus.hosiene.co.uk/viewforum.php?f=40 help on the forum]
== Additional Steps ==
:* Add a DHCP reservation
:* Assign a static IP address
:If you need to use a fixed IP address for your Raspberry Pi, there are 2 methods
1. Adjust your router settings to always assign the same IP address. This facility has different names on different brands of router, look for a section named DHCP. You may be able to choose the IP address (possibly within or possibly outside the range assigned by DHCP), or you may only be allowed to choose 'always assign the address it currently has'. You may need to know the MAC address of the Raspberry PI, but if so that will likely be displayed alongside the current connection.
2. Adjust Raspberry Pi settings to always request the the same fixed address. This is less reliable, because your router may have assigned the requested address to a different device since the Pi was last active. To do this you have to edit this file: « '''/etc/network/interfaces''' »
:For Ethernet connection a line specifying port '''eth0''' is needed to describe your ethernet configuration, as the example below. For a wireless connection, it needs similar with '''wlan0''':
allow-hotplug eth0
iface eth0 inet static
address 192.168.11.100
netmask 255.255.255.0
gateway 192.168.11.1
dns-domain example.com
dns-nameservers 192.168.11.1
''The line "dns-domain example.com" is optional''
:You could have also to edit an other file, for dns configuration.
:see file «'''/etc/resolv.conf'''» to insert these lines:
nameserver 192.168.11.1
domain example.com
''Again, the line "domain example.com" is optional''
== Information ==
If you previously used Microsoft Windows with each part of a path separated by "\", please remember that all other operating systems, including that for Raspberry Pi, use "/" to both indicate the root (at start) and to separate parts of a path, as per the install location shown next.
=== Install location ===
In this image Cumulus MX is installed into '''/opt/CumulusMX'''
=== Image Customisations ===
* Based on the 'Lite' version of the Raspberry Pi OS (ie the graphical desktop GUI is not included; it can be added later if you want it)
* Full install of Mono
* Update of all packages
sudo systemctl enable cumulusmx
: To stop Cumulus starting at boot time:
=== Starting Cumulus MX from the command line ===
You may want to start Cumulus from the command
First make sure the Cumulus MX service is stopped
sudo systemctl stop cumulusmx
Then path to the Cumulus folder and start it<br>
(Noting it is case sensitive).
cd /opt/
sudo mono
=== Symbolic Links ===
The image contains a number of precreated symbolic links for Cumulus MX files such as realtime.txt and the standard website tmp files. These links divert these files to a memory disk to reduce wear on your SD card.
