What is shelly-1-gen4-matter-thread?

This C++ firmware turns the Shelly 1 Gen4 relay into a native Matter-over-Thread device, unlocking its unused Thread radio for direct control from Apple Home, Google Home, Alexa, or Home Assistant—no WiFi, cloud, bridges, or apps needed. It implements an On/Off Light device type with latching relay behavior, perfect for lights, fans, or outlets that hold state. Users get multi-fabric support, physical button toggles, external switch input, and Thread routing to extend meshes.

Why is it gaining traction?

It's the first GitHub repository ever delivering open-source Matter over Thread for Shelly hardware—like the first Matterhorn summit for smart relays—bypassing Shelly's WiFi-only stock firmware. Developers dig the no-middleware setup, state sync across ecosystems, and detailed flashing with ESPConnect or esptool, including backups to avoid bricking. Low-power Thread shines for reliable, off-grid control without WiFi congestion.

Who should use this?

Shelly 1 Gen4 owners tired of cloud dependencies or HA bridges. Smart home hackers building Thread meshes with HomePod minis or SkyConnect. Off-grid RVers or vanlifers needing battery-friendly relays for lights and heaters.

Verdict

At 45 stars and 1.0% credibility, it's an early v1.0.0 project with solid README docs but open roadmap items like power-on configs and switch variants—flash at your own risk, voiding warranty. Worth it for Thread pioneers evaluating shelly-1-mini-gen4-matter-over-thread today.
