A custom Home Assistant integration for Brunata Online accounts — track water, energy, and heat cost allocator meters directly in your dashboard, fully automatically.
Installation & setup · Using the sensors · Sensor availability · Debugging · Report an issue
- Automatically discovers all meters on your Brunata Online account
- Supports water, gas, energy and heat cost allocator meters, and reads every other meter type Brunata reports — see the README for the full list of units
- Names devices after the placement you set in Brunata Online, so a meter appears as
Water - Bathroom (Cold)rather than a serial number - Groups sensors under devices for a clean dashboard
- Uses standard Home Assistant device classes and state classes, with full Long Term Statistics support
- Polls hourly via
DataUpdateCoordinator, scheduled every hour at xx:59:30
