Restict Thermostat to temperature only

Hi,

I need some assitant to see if I can restrict the use of my thermostat to temperature only.

I have a BHT-6000 that I flashed using TuyaConvert.
So that one only handles temperature and is setup as climate in Home Assistant so it can be fully controlled.

I’ve created a small humidity sensor using ESPHome & I exposed that sensor as device-class: humidity so I can ask google assistant to provide me the value.

Both the thermostat and the sensor are in my living room. So here comes the problem:
When I ask google to provide my the humidity in my living room, it both requests it from the sensor and from the climate device. However because the thermostat does not have any humitity reading, Google tells me it cannot access my thermostat.

Is there a way to tell google that my thermostat is only doing temperature, so I won’t get the error message ?
