SonoffLAN
Control Sonoff Devices with eWeLink (original) firmware over LAN
...The integration avoids the need to flash devices with custom firmware, which makes it practical for users who want Home Assistant control without modifying hardware. It supports single-channel and multi-channel devices, TH and POW sensors, RF Bridge commands, local multicast updates, and cloud WebSocket updates. It can load device names and encryption keys from eWeLink servers and store them locally for future use. SonoffLAN is best suited for smart home users who want deeper Sonoff automation while keeping the official device firmware.
