Location of city villa or single-family house on 500 m2 plot - rectangular

That would be way too easy and smart. Yes, I have to climb the scaffold with [Smartyfon] tonight.

North side? Outside temperature sensor?

(That was a cable for us back then that I couldn't assign)

Well, northwest. But the temperature sensor should actually be on the northeast, basically at the technical room. So he had to go across the whole house. But good tip, I'll check if it's missing on the outer wall there. Then it would be that one. I wouldn't really like that because it would then be on a potentially warmer side. It’s supposed to be on the coldest side, right?

So, here is the little picture. I think it is really the outside temperature sensor. There is no cable at the location designated according to the plan. For some reason, either the master planned again or the journeymen just executed it differently. In the end, it probably doesn't matter. How big is such a sensor actually?

I only know the sensors as a small gray box measuring approximately 7cm x 7cm

Our sensor is white and about the size of a cigarette box
