Hi,
I’m not sure if the pollin frequence is the problem. The thermostat should poll the esp32 each 10 seconds more or less. If the thermostat is polling faster, then something is wrong with the app.
In the future I can add a settings to configure the polling frequence.
I don’t have very much time in the next few days, but I will have a look at the sketch and the app asap.
Thank you for your efforts.
