Homebridge ETA REST Homebridge plugin for ETA pellet boilers using the official ETA REST API.

This plugin exposes key boiler temperatures to Apple Home via Homebridge.

FEATURES

The plugin currently exposes the following sensors:

• Boiler flow temperature
• Domestic hot water (DHW) tank temperature
• Outdoor temperature Each value is exposed in HomeKit as a temperature sensor.

REQUIREMENTS

• Homebridge >= 1.8
• Node.js >= 18
• ETA boiler with REST API enabled
• Network access to the ETA controller The ETA REST interface usually runs on: http://ETA-IP:8080

INSTALLATION

Install the plugin globally: npm install -g homebridge-eta-rest or install it directly from the Homebridge UI -> Plugins tab.

CONFIGURATION

Example configuration in config.json:

{ "platform":
    "EtaRestV3", "name": 
    "ETA REST", "baseUrl": "http://ETA-IP:8080/user/var", 
    "pollInterval": 60, 
    "paths": {
    "boilerFlowTemp": "/120/10101/0/0/12241", 
    "dhwTemp": "/120/10111/0/0/12271", 
    "outdoorTemp": "/40/10241/0/0/12197"
    } 
}

Configuration options: baseUrl Base URL of the ETA REST API. pollInterval Polling interval in seconds. paths ETA variable paths for each sensor.

HOW IT WORKS

The plugin polls the ETA REST API periodically and reads the configured variable endpoints. Example REST call: http://ETA-IP:8080/user/var/120/10101/0/0/12241 The returned XML value is converted and exposed to HomeKit.

Note: This is my very first Homebridge plugin. After several months of private use, I decided to release it as open source. Feedback and suggestions are very welcome!
