FanControl.HomeAssistant

FanControl-Plugin for HomeAssistant sensors.

• Integrates HomeAssistant temperature sensors into FanControl
• HomeAssistant for example provides Philips Hue Ambient temperature sensors or HomeMatic thermostat data as temperature sensors
• Initial use case: Implemented to be used as an ambient temperature sensor for a custom loop.

Installation

Download the latest release and drop the .dll- files into FanControl's Plugins folder. Make sure to have the latest FanControl release installed.

Configuration

The Plugin Expects a file FanControl.HomeAssistant.json within FanControl's Configurations directory (next to your default userConfig.json). If this file is not found, a non-working default configuration file will be created. Check the error log (accessible from the FanControl menu). The default configuration file will look like this

{
    "HomeAssistantAuthToken": "your_long_lived_access_token_created_from_home_assistants_user_configuration",
    "HomeAssistantURL": "http://example.com:8123",
    "sensors": [
        {
            "EntityId": "sensors.your_temp_sensor_entity_id",
            "PollingInterval": 10,
            "InitialFallbackValue": 10.0
        }
    ]
}

After each configuration change, you have to restart FanControl for your changes to have any effect.
