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, energy and heat cost allocator meters
- 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 Brunata once an hour via
DataUpdateCoordinator, at xx:59:30 — how often a new reading appears depends on the meter's own reporting interval, not on this schedule
For installation instructions and general setup, see the README. This wiki covers usage details that go beyond what fits in the README.

| Debugging | Which of a diagnostics report and a debug log to attach to an issue, how to produce each, and what they contain |
