About

Silla Prism EVSE is a custom integration that connects a Silla Prism EV charger to Home Assistant. It communicates locally through an MQTT server that the charger and Home Assistant both use. It adds binary sensors for touch events, connection status and error status, plus buttons to authorize or revoke a charge. Number and select entities set the current limit and the port output mode, and sensors report values such as output current, grid voltage, power to the car, session energy, total energy and CPU temperature. Optional virtual sensors derive extra values, such as total energy drawn from the grid, and Powerwall sensors can be enabled. Setup is done in the UI, where the MQTT base topic, number of ports, a unique device code and a maximum current are entered.
