Home Assistant: home battery guide

See where your electricity goes

The Energy dashboard can combine grid imports, solar production and battery flows from compatible integrations. Correct energy sensors are the starting point for understanding how much energy is stored, used and exported.

Monitoring and control are separate checks

An integration that shows state of charge may not expose charging controls. Before building automation, check the documented features for your inverter, including whether the integration is local or cloud-based and whether it can write the settings you need.

Add rules or a planning engine

Home Assistant supports user-defined automations. A planning tool such as PredBat can be added for forecast-led battery scheduling. A dashboard alone does not establish an optimal charging strategy; the rules and input data determine the behaviour.

A practical setup sequence

Begin by observing data and comparing it with the manufacturer app. Introduce control changes gradually, with a clear way to return to a known schedule. Document your tariff windows and reserve requirements, and check operation after updates or tariff changes.

• Confirm reliable measurements
• Verify supported control commands
• Define reserve and fallback behaviour
• Monitor the first charging cycles
