Termo Glass 230V Temperature?

I am trying to make sure my house and save as much energy as possible (energy cost in Sweden right now is crazy) …

I have an Termo Glass 230V that I could install easily into my “Smart Life” app, getting it available in HA thanks to Tuya.

The problem?
For whatever reason, it’s marked as “Unavailable” in HA.
Doesn’t matter if I turn it on / off with the Smart Life app, it still doesn’t change anything in HA.

My end-purpose would be to get the temperature from the room (as the heater seem to have this information in the end), and depending on the temperature, run different automations depending on weekdays etc.

I am quite new on this topic, so please bare with me on this :stuck_out_tongue:
