accessory	Must be Thermostat
name	Name to appear in the Home app
apiroute	Root URL of your Thermostat device (excluding the rest of the requests)
temperatureDisplayUnits (optional)	Whether you want °C (0) or °F (1) as your units (0 is default)
currentHumidity (optional)	(true or false) Whether to include currentRelativeHumidity as a field in /status (false is default)

API Interfacing

Your API should be able to:

1. Return thermostat info when it recieves /status in the JSON format like below:

{
    "targetHeatingCoolingState": INT_VALUE_0_TO_3,
    "targetTemperature": FLOAT_VALUE,
    "currentHeatingCoolingState": INT_VALUE_0_TO_2,
    "currentTemperature": FLOAT_VALUE
}

Note: You can also add the currentRelativeHumidity and targetRelativeHumidity fields individually or together above if enabled in the config.json (read Structure)

2. Set targetHeatingCoolingState when it recieves:

/targetHeatingCoolingState/{INT_VALUE_0_TO_3}

3. Set targetTemperature when it recieves:

/targetTemperature/{INT_VALUE}

4. If enabled in config.json (read Structure), set targetRelativeHumidity when it recieves:

/targetRelativeHumidity/{FLOAT_VALUE}

HeatingCoolingState Key

Number	Name
0	Off
1	Heat
2	Cool
3	Auto

Heatmiser Support

Folder 'heatmiser' contains a contributed example of the API. It supports Heatmiser wireless thermostats, as long as https://github.com/thoukydides/heatmiser-wifi is installed and working.
