Both are showing correct with one decimal, then again in Europe we use centigrades. Homey also internally uses centigrade for all calculations only converts the value to fahrenheit for presentation in the UI.
I am now testing also the flow cards to verify your situation:
but since those are the ones provided by Homey as standard for thermostats having measure_temperature capability, there is not much I can do to change that. However if we do find a bug, we can report it to Athom and hope for the best.
