This repository contains a Home Assistant custom integration for the Brunata user portal.

• Copy the folder custom_components/brunata/ to:
  • /config/custom_components/brunata/
• Restart Home Assistant.
• Open Settings → Devices & Services → Add Integration → Brunata.

• Copy the folder custom_components/brunata/ into your HA config directory:
  • <config>/custom_components/brunata/
• Restart Home Assistant.

• Add the repository as a Custom repository in HACS (type: Integration):
  • https://github.com/fjfricke/brunata
• Then install Brunata and restart Home Assistant.

You need portal credentials that work with the Brunata portal. In the config flow you can set Base URL, SAP client, and language (defaults fit the Munich portal).

You can change the update interval via the options flow.

• For each CostType (e.g. HZ01, HZ02, WW01 …) separate sensors are created:
  • Monthly consumption (kWh) (sensor.*monthly_<cost_type>)
  • Meter reading (sensor.*meter_<cost_type>, unit e.g. Einh. or m³)
  • Cumulative consumption (kWh) (sensor.*kwh_total_<cost_type>, total_increasing)
• Dashboard periods (diagnostic)

• The cumulative kWh sensors are also written as long-term statistics into the recorder.
• The cumulative kWh history is built as a cumulative sum from the monthly values and imported.

• This integration uses your portal credentials to fetch data from the Brunata portal.
• Only share logs/dumps in anonymized form, as they may contain personal data.
