A local-push integration for Fronius Wattpilot wallbox chargers. It talks to the charger over its WebSocket API on your own network: no cloud account, no polling. When the charger pushes a property, exactly the entities that use it update.
It replaces the two earlier community integrations under the same
wattpilot domain and keeps their entity IDs: the unique IDs of
ruaan-deysel/ha-wattpilot stay as they are, those of
mk-maddin/wattpilot-HA are rewritten once. History, dashboards and
automations survive the switch (see Migration).
- Fronius Wattpilot chargers on the local network, 11 kW and 22 kW variants.
- Developed and verified against a Wattpilot Home 11 J 2.0 on firmware 42.5.
- Wattpilot Flex: supported from diagnostics a Flex owner shared (firmware 43.4 and 43.5), not tested here.
- Go models speak the same API but have not been tested.
- Cloud connections are not supported. Use the charger's local address.
Requires Home Assistant 2026.9.0 or newer.
- Installation and Setup: install, connect, options, remove
- Entities: every entity with its charger key, unit, category and range
- Actions: the four actions and their fields
- How Data Updates: push, update interval, reconnects
- Troubleshooting and Diagnostics: error messages, diagnostics, logs
- Migration: coming from an earlier Wattpilot integration
