Thank you Doug, this is more or less the roadblock(s) I've come against too, I've tried this fruitlessly since 2019 with no luck so I figured I would finally post about it to see if anyone has had any concrete luck. Thanks for the recommendation of the AS3925, I believe that is the same core-sensor on the 06045M with a different wrapper on the SDR, so that is probably challenging. I just liked it due to the audio/visual warnings it produces in use at home, as well as the added value of extra temperature/humidity readings, which albeit work fine.
Thanks again, Mike. On Monday, March 7, 2022 at 11:59:36 AM UTC-4 [email protected] wrote: > I have tried my hand in this device last year with SDR and MQTT.
