I make an SetThermostatMode command but in my logic this is not possible, so I've created an error body response with the namespace: Alexa.ThermostatController.
I have this two examples for this command:
Alexa, set the thermostat to heat -> I'm not quite sure what went wrong - The wrong message.
Alexa, set the thermostat name to heat -> That command doesn't work on device - The correct message.
Why is my response body handled differently?
