Thermostat - Smartthings state not consistent with Homekit
The state of the thermostat as reported through Smartthings is not being reflected in Homekit enabled App.

Within Smartthings, the thermostat has the following state:
- Current Temp: 23.2
- Setpoint: 18.0
- Fan Mode: Auto
- Mode: Heat

Within Homekit enabled App, the same thermostat has the state:
- Temperature: 0.0C
- Heating Threshold: 0.0C
- Cooling Threshold: 10.0C
- Mode: Off

Manually invoking the API returns (abbreviated body):
