I've created a plugin for my EvoHome system.
One of the devices is of type "thermostat" and represents the controller in the EvoHome system.
It doesn't have a temperature setting, but it does have a heat demand.
It is that property that I fill in the plugin and the Indigo Client happily shows it.
Indigo Touch however shows a temperature and also show the temperatures in Fahrenheit.
Is this a bug in Indigo Touch?
