A cheap 433mhz emiter can be buy for less than 1€ (actullaly i'm driving my cheap rc switch with one of this, and a lua script and that works like a charme, i'm on the way to get state of this rcswitch if somebody use the remote)

With this of course you have to made your own script and use differente app to make Domoticz as full fonctionnal it can, hobby time is free.

Do you still use this setup?
I also have this 433mhz transmitter but have no idea how to set this up with nu Rpi and Domoticz.

If someone is interrested or want to give me a hand coding, pplease let me know. Written in python.

        curl  $AUTH "${BASEURL}&idx=${TEMPIDX}&svalue=${TEMP}"
        curl  $AUTH "${BASEURL}&idx=${DEPTHIDX}&svalue=${DEPTH}"
    done

Ideally though, I think Domoticz would spawn rtl_433 for itself and just read the JSON from its stdout. Or if that's too painful to do under Windows then perhaps we could teach rtl_433 to publish its findings via MQTT. Then we'd have to add support for that to Domoticz, a bit like the existing MySensors support.

Yes, but note the subsequent comment about tracker ticket #691(although the tracker seems to be down atm or just entirely absent). Make the 'AUTH=' line look like this (with your own username and password, of course, and your own choice of where to store the authenticate cookie):

Code: Select all

AUTH="-u oiltank:$PASSWORD -b .domocookie -c .domocookie"
