aggregation for observation? #214

Closed poblabs closed 1 month ago

poblabs commented 1 month ago

Hey there, I have a 2nd anemometer that I have sending data to mqtt. Using mqttsubscribe as a service i'm able to get windSpeedFlagpole and windGustFlagpole into the loop just fine. My question is with the archive though. It's averaging both observations which is expected. How can I specify that windGustFlagpole should be the max over the archive interval?

MQTTSubscribe uses core WeeWX functionality to create archive record from the loop packet data. You will want to set the extractor of the windGustFlagpole to max. See, https://github.com/weewx/weewx/wiki/Accumulators, for more information. Disclaimer: I don’t fully understand WeeWX handling of wind data, but if you just need the max value for a given archive period the above should work.

Awesome! Thanks for pointing me in the right direction
