Using a Insteon 2441TH thermostat
Thermostat set to Celcius
Echo app set to metric

If I tell Alexa to set the temperature to X degrees, it usually works fine and she responds with the correct number.
If I tell Alexa to increase or decrease the temperature, it also works but she responds with a value exactly double of the set point. (eg. 18 becomes 36 but still correctly shows 18 in ISY)
