Cumulus MX builds only. | |||
'''UseDavisLoop2=1''' Cumulus MX will use the LOOP2 packet for Davis Weather Stations by default. | |||
The current MX code uses this for two purposes. First, it uses the 'peak 10-minute gust' value, to avoid the problem where a gust might be missed, and secondly it uses the 'absolute pressure' value to make calculation of 'altimeter pressure' easier and more accurate. This is mainly used if you upload to CWOP. | |||
The LOOP2 packet is supported on the VP2 with firmware version 1.90 or later, and on the Vue. If you have a Vantage Pro (i.e. the original 'VP1'), or a VP2 with pre-1.90 firmware, or if you are using Virtual VP, none of these support the LOOP2 packet. In these cases, you should edit ''cumulus.ini'' (with Cumulus stopped) and add a line to the [[Cumulus.ini#Station|[Station]]] section: | |||
'''UseDavisLoop2=0''' | |||
With this setting, Cumulus will revert to calculating the 10-minute gust value itself from the individual wind speed readings, but it will not currently attempt to calculate altimeter pressure correctly, it will simply use the sea-level pressure instead. This is likely to be an issue if you are at high altitude and you upload to CWOP using Cumulus MX. | |||
