| Silla Prism EV wallbox | Partly works Local | Local MQTT; only first port on Prism DUO, no load-balancing controlsSaved copyLimitations: Only the first charging port is supported. On a Prism DUO, the second cable is not exposed. The current limit used for custom load balancing, the night schedule, and charge authorization are not exposed yet. Solar and home power flows are only meaningful when a Powerwall or compatible meter is configured on the Prism; otherwise they report 0. Excerpt saved from home-assistant.io on 2026-10-23. | Docs |
