# Refoss RPC (Official Maintenance)

> Refoss RPC (Official Maintenance) is a Marketplace integration for Home Assistant. It has 816 installs sharing analytics, works locally and was last updated October 21, 2026.

Refoss RPC (Official Maintenance) connects Refoss devices that use the RPC protocol to Home Assistant. It works locally, without a cloud connection, and the description lists the R11, R21, P11s, EM06p and EM16p as supported models. It adds binary sensors, buttons, covers, events, sensors, switches and update entities. Device triggers cover single, double, triple and long push as well as button down and button up, so devices can start automations directly. Home Assistant can discover a device on the network and offer to add it, or the host and an optional password can be entered in the UI. It requires Home Assistant 2025.2.5 or newer.
