It's sort of irrelevant in that the ambient external temp is what you'd expect it to be. The temp on your weather app is going to be reasonably close to, in this case, my back yard porch while I enjoy my morning smoke and coffee at 630am.
The whole thing started with "why is my car telling me it's 22 when it feels like 5 and my Iphone says it's 5. What dark sorcery is this? Surely these Germans don't make inaccurate thermometers!"

 

The Toyota is actually dying a slow death in the driveway. I had to recharge the battery the other day. It hasn't been driven in months.

 

Maybe that's why Toyotas last so long
