NS Panel, Thermostat temperature accuracy

I’m using the thermostat from NS Panel but unfortunately the temperature accuracy which can be set is +/- 1 degree which is creating a discomfort as practically will be a difference of 3 degrees between start and stop of the heating system . Can be updated to have a temperature accuracy of +/- 0.2 degrees?
Or there is any solution to reduce the difference between start and stop temperature?

Thank you in advance!

This has been raised many times and seems to be a hardware issue. Best to contact Sonoff, I have already :slight_smile:
