Adding additional sensor info from a DHT22

From build 3044 the development baton passed to Mark Crossley. Mark has been responsible for all the Builds since. He has made the code available on GitHub. It is Mark's hope that others will join in this development, but at the very least he welcomes your ideas for future developments (see Cumulus MX Development suggestions).

Adding additional sensor info from a DHT22

Post by bab5871 »

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.
