[RELEASE] Mode Based Thermostat - Control Multiple Thermostats Temperature / Remote Temperature Sensors when Changing Modes

[maddie (Head of Support (rboyapps.com))]

Hi there. That means either the smartapp and the devices aren’t installed in the same SmartThings location (check the IDE or mobile app) or the device is not using a compatible device handler that conforms to the SmartThings specifications.
If it’s the latter, you can change the device handler from the IDE to use the stock zwave device handler or use our Enhanced zwave thermostat device handler and SmartThings will automatically allow you to select it.
