I think, if the sensor is on 915 MHz, you'll have to issue some parameters on the command line when you start RTL-433.  I think it can be done with one command line, to make it scan 433 and 915, switching periodically.  It's not difficult.
ESP32, ESP-NOW, InfluxDB, NodeRed, RFLink, RTL_433, Acurite Atlas, RaspPi.

Yes, as long as it can decode it in the first place, I'll get it to work. Will let everyone know how it goes. Sensor will arrive on Thursday, so don't expect any news until next weekend.

Thank you everyone!

You ordered the Ambient WH32B? Because that is only 915 MHz. Will your RTL-SDR work with both 433 and 915 MHz? From what I understand there are different antennas for the various frequencies. Therefore I think you should stick to 433 MHz like your other sensors.

I purposefully only mentioned the Ecowitt WH32B because it can be ordered with any frequency; 433, 868, or 915 MHz.

I contacted EcoWitt to see if I can get it. Will let you know.

Thank you!

EcoWitt will sell it separately for $12.99 incl. mail ship, but will take 4-5 weeks :-( So I'll wait and first check if the Ambient one works.
