Thermostat in GoogleHome

Hi,
i have an Sensor in HA for my Pooltemperatur and this show me the correct Value.
Now i would like to expose this sensor to GoogleHome - so i can ask Google:

“Hey Google - what is my Pooltemperature?”

Google said: Pool is…:slight_smile:

All works fine.

But the i can’t see the Temp in Google Home.
The device is recognized as a standard and not as a temperature sensor.
How can I change this?

Thx.
Regards
Herbert
