I'm struggling to set the correct time on the Sensocomfort, no matter what I do - the time always seems to revert to Time + 1 hr 

I have set the time manually and kept the DST manual - after midnight, the time adjusts to the Time + 1hr 

When I have set the time manually and kept the DST Automatic - after midnight, the time adjusts to the Time +1 hr 

No matter what the DST is, if I adjust the time - after midnight, it automatically adds +1 hr

 

Any help would be appreciated.

Oh I remember this from when I set mine up 2 years ago, same problem, big mystery. 

Solved eventually by changing the time zone on the app to something other than London, saving, then reverting it back again, then repeat.


4kW peak of solar PV since 2011; EV and a 1930s house which has been partially renovated to improve its efficiency. 7kW Vaillant heat pump.

Thank youy for the pointer.  I think I have managed to find the problem.  

The time zone option shows - Europe London (which is incorrect), the correct one is GB!
