I use a BME280 sensor for outside and some 18b20's for inside. Domoticz works with these without problems but I do not use OTA - not figured that out yet :disappointed_relieved: :laughing: I had to cut out all the weather prediction code on for the BME280 to make it run on a pro mini 3.3 but Domoticz has basic prediction built in.

@pjr said in Presenting and controlling variables in domoticz: Cannot get the point what you exactly mean but I think you should check for what child the message is for: if(message.sensor == CHILD_ID_aeg2** && message.type == ...) { ..do suff.. } Thank you, message.sensor was the thing i needed. Browsed cpp and h files in mysensors library and googled, but couldn't find variables to use with message.*. :smiley:
