SEMP compatible

← Chargers

This page shows the nightly version. Switch to the release version.

SEMP (Smart Energy Management Protocol) compatible wallbox or device that can be controlled directly via HTTP/XML API. Configure the SEMP base URL (http://<charger-host>:8000/semp) and the device ID of the wallbox. IMPORTANT: The wallbox must NOT be registered directly as a consumer in the Sunny Home Manager / Sunny Portal at the same time!

Supported features

• mA regulation: Finer charging current regulation (mA instead of A) for better solar surplus use.
• 1P/3P: Automatic phase switching. Useful for solar surplus charging.
• Built-in meter: Support for an integrated meter.
• Dimmable: Power consumption can be reduced (e.g. § 14a EnWG). See External Limit.
