Cumulus Support

Currently running CumulusMX on a raspberry pi 3b+ with a Davis vantage pro 2 plus and wanted to add some extra indoor temp/humidity sensors. Is it possible to add a DHT22 to the pi to record indoor temp/humidity and have it logged/charted/displayed somewhere? How difficult would that be?

The only real way of doing this is to take the data from your sensor and send it to CMX using the Ecowitt HTTP extra sensor configuration.

The Ecowitt protocol is a HTTP POST with the data in the body in id=value pairs.
