Entity not found - local tuya

Hi
I am a newbie but hoping someone can help. I have been using a thermostat through local tuya integration. It all worked fine but suddenly HA says ’ Entity not available’. I tried to remove the integration and add again, but now I get this error. Anyone else had similar issue?
