Good that you got it working! Also, nice surprise to see Swedish on your screenshots
I’m using it for the exact same purpose and would also like to do that.
So I have researched this before because I also have some Aqara temperature/humidity sensors that display humidity by default and I would instead want to show temperature on the app tile. I couldn’t find a way to do it in the new app and I am trying to stick to that as much as possible so it doesn’t hurt as much when Samsung cuts the Classic app, whenever that happens.
However, there seems to be a way to edit the default tile metric on the Classic app but I haven’t tried it myself. Maybe you are OK with using the Classic app so here’s the link to what I found, if you’re interested:
Hope it helps. Lycka till!
