Finally got HA on a Raspberry Pi, still a few quirks I can't figure out with AVM Fritz!Box

Ok, so I found out that I had to modify my AVM router config a bit, and now it can connect to it.
When I look under configured devices, it is not shown like the Nest, or IKEA units, but the items are shown on the overview?
One thing that I’m missing in the overview is the temperature readings from my Fritz contacts. If I go and watch the units the temperature readings are in there. How do I get them to the ‘overview’
