The App for the Bluetooth version I ordered is not supported on Android 13 and there is no mention of that anywhere. Also I was not yet able to find how to configure all the functionality just using the on screen interface. For example I haven't yet been able to change from °F to °C. And also the automatic/manual setup is not intuitive how to set up when to sue what.
Else the the heater has performed great and I have nothing but praise for the functionality for which it is intended. It heats up the space and that's what matters at the end. The additional functionality looks like a nice to have but is not required if you just need to turn this on and off manually.
