Hi Íñigo,
If you modify my custom Handler, you can have different reports on the mobile App : the lines to modify are lines 119-182 of the latest v0.9.7.2 Handler.
The developers Tiles documentation is there.
If you are not familiar with programming, I would however suggest that you abstain since the SmartThings environment is way too much quirky and you may end spending way too much time for a little enhancement.
YMMV…
Note also that since you do not use the temperature sensor, you could as well modify the Tiles section of the SmartThings FGK-10x standard Handler (the one used by default when you first pair a new FGK-10x to your Hub).
Have fun (?)
