NRG.Watch Itho (API)
The temperature changes
NRG.Watch Itho add-on
Control and monitor your Itho ventilation system via MQTT or API in Homey (requires the NRG.Watch Itho add-on).
Warning! This app might not work properly.
This app version is currently being tested, and has not yet been reviewed. It might not work as expected.
Be extra careful when installing this app.
Integrate your Itho ventilation system with Homey using the NRG.Watch Itho add-on hardware module. This integration enables automated climate control based on humidity, temperature, or time schedules, creating a healthier and more comfortable indoor environment.
Connect via MQTT for real-time updates or HTTP API for polling-based control. Monitor indoor climate with temperature and humidity sensors, control fan speeds and presets, and track system health with error monitoring and diagnostic data. The app supports both standard Itho units and systems with CC1101 RF modules for extended functionality.
Set up is straightforward: add the device in Homey, choose your connection method (MQTT or API), select your Itho device type, and configure the connection settings. The app handles all communication with your ventilation system automatically.
