# Silla Prism

> Silla Prism is a built-in integration for Home Assistant. It has 24 installs sharing analytics and works locally.

Silla Prism is a built-in integration that connects a Silla Prism charger to Home Assistant locally. It reads the charger through the MQTT topic prefix that Prism publishes to, which is entered during setup in the UI. Home Assistant can also spot the device on the network and offer to add it. Sensors report status, errors, grid power, pilot current, session start, session energy and total energy. A number entity sets the maximum charging current, and a select entity switches the charging mode.
