Wasn’t sure where best to post this, but wondering if anyone has any ideas. I purchased some Ecowitt 915mhz sensors to setup a weather station and temp sensors around a new property. I have an existing setup with HA at another location that’s working well but those are 433mhz and I didn’t want to bother with that installation.
In any case. I setup a test raspberrry Pi with a NooElec NESDR Nano 3 and a docker image of rtl_433 to test the sensor. I didn’t get anything out of rtl_433 so I fired up the gqrx sdr app, tuned to 915mhz and put the battery in the sensor and got a reading, and periodically I’m getting what appear to be readings from it so i can tell the SDR is working and the sensor does indeed seem to be transmitting where I think it should.
Below is what I have that I let run overnight. I’m confident it’s protocol 221, but I even let it run with “everything” and it never detected this sensor. It should be supported and should work on this version, but looking for advice to further troubleshoot it… If there’s a better place to post this let me know.
