Hello,
issue for unsupported attribute error

Deleted lines : 
await reporting.thermostatUnoccupiedHeatingSetpoint(endpoint);
await reporting.thermostatUnoccupiedCoolingSetpoint(endpoint);

Check issue : Koenkk/zigbee2mqtt#17211

This error stop the other reporting like occupancy and humidity.

Tested on my box.
