Example Thermostat SDK

I discovered via the Example device - Thermostat SDK plugin example that to be able to define multiple sensors, you have to set the property: NumTemperatureInputs.
Likewise, for number of humidity sensors, you have to set the property: NumHumidityInputs.

These properties aren't documented in the ThermostatDevice documentation AFAICS.

A minor coding correction method _changeHumiditySensorValue, on line 83 of the plugin:

Code: Select all

      keyValueList.append({'key':stateKey, 'value':value, 'uiValue':"%d °F" % (value)})

should be

Code: Select all

      keyValueList.append({'key':stateKey, 'value':value, 'uiValue':"%d%" % (value)})

However, I am not sure the humidity gets displayed as when you define zero temperature sensors, a default initial temperature value of 66.5 °F is shown when I suspect the humidity value should be shown when (assuming there is at least one humidity sensor defined.

Thanks for the _changeHumiditySensorValue() buglet report. I fixed it but used "%d%%" instead of "%d%" to avoid an error.

You are correct that thermostats always show the temperature input/sensor values as the main state UI, unfortunately even if there are no temperature sensors. I believe the 66.5 you are seeing is a left over state or caching issue and for a newly created device that has NumTemperatureInputs set to 0 it will probably show "unknown."
