I am sure this question may have been posted somewhere in the forum already.

If I select the option for the outside temperature to be taken account of in the Control Panel does it do no more than bring the heating on earlier if it thinks it is below a certain level? That then sounds like optimisation. Once the day has started and the heating has been fired up surely the rooms will be kept to their set level no matter what the outside temperature?

I have kept checking what the app thinks the outside temperature is and what it actually is and always about the same. Both show 2c as I type this.
