If I look at the HA log, the thermostat seems to disconnect and reconnect itself every few minutes. Does yours do that? After looking closer at it, I think this is an issue with the Rheem thermostat not staying connected to the home WiFi network.
Also, have you considered wiring in to the thermostat directly to avoid having to use a Rheem account?
Finally getting back to this. I only recently discovered I can use the diagnostics port to try and control it directly. I'm probably going to attempt that but need to get some hardware.
I still don't seem to have any issues with connecting or disconnecting.
I ordered the stuff and setup the ESPHome-Econet solution. It works really well! I actually deleted the Rheem integration just now because the ESPHome solution is so much better. It was cheap and easy to setup too. I spent about $25 US buying the parts from Mouser. (I used an old phone cable, so I didn't have to buy that)
