About

Growatt THOR EV Charger connects a Growatt THOR EV charger to Home Assistant locally over OCPP 1.6. It works without the Growatt cloud and is set up in the UI, asking for a port and an installation location. It adds buttons to start and stop charging, numbers for maximum current and load balancing limit, selects for charging strategy and authorization mode, switches, time entries for scheduled charging, and many sensors. Sensors cover charger status, power, current and voltage per phase, session energy and temperature, and are compatible with the Energy Dashboard. Options include a local RFID allowlist and a choice to allow starts from Home Assistant. It is an unofficial community project, tested on the THOR 22AS, and the README warns of firmware reboots on the charger.
