I just purchased the 202U v6 Kit-1 from Amazon. When I got the kit, I tested the remotes on my SDR and didn’t see them transmitting anywhere near 433.92mhz. The light on the remote was coming on solid (mode 1) so I was confused why I couldn’t see it. I paired the remote with 202U and it functioned as expected, but I still was not seeing the transmission at 433.92mhz.
I found that remote was transmitting on 372.500mhz. By looking at the report that was submitted (2017) to the FCC for the ID printed on the remote, the OOK mode should be transmitting on 433.92mhz and the FSK on 433.22, 433.92, and 433.62.
I switched modes on the remote and it is working as expected on the latter 3 channels.
Can you please explain why the remote/receiver pair is transmitting in a licensed band (372.5mhz) and not 433.92mhz, which is advertised in the Amazon description?
My reason for looking at this so close is I already have a 433.92mhz receiver listening and recording ALL traffic. I do this logging for various reasons. And, I send certain traffic to an MQTT server, such as weather station data, wireless alarm sensors, and tire pressure sensors. My plan was to create an MQTT topic and push notifications that identify which remotes opened a gate or garage door. I can’t really do that now without setting up a new receiver to listen on 372.500mhz <–not my preferred solution.
