    Configuration Sample

    "platforms": [
                "platform": "tcc",
                "name" : "Thermostat",
                "username" : ".....",
                "password" : ".....",
    • platform: tcc
    • name: can be anything you want, this is only used in the homebridge logs and is not the thermostat name
    • username: your Honeywell e-mail
    • password: your Honeywell password

    Optional settings

    • refresh - Data polling interval in seconds, defaults to 10 minutes. Setting lower than 10 minutes may trigger request rate limiter on Honeywell backend.
    • storage - Storage of chart graphing data for history graphing, either fs or googleDrive, defaults to fs
    • usePermanentHolds - If set to true, temperature changes will be set as permanent holds, rather than temporary holds. This will allow you to use HomeKit automations to completely replace your thermostat's schedule. If set to false, the temperature changes will expire after a certain period of time and resume your normal schedule. By default, this is off.
    • sensors - Enables temperature/humidity HomeKit sensors (useful for automations), options include:
      • none - No sensors will be shown (this is default setting)
      • all - Enables all available temperature/humidity sensors
      • inside - Enables temperature and humidity sensors for each thermostat
      • outside - Enables a single set of outdoor temperature and humidity sensors
    • debug - Enables debug level logging from the plugin, defaults to false, to enable set to true
