What it can become

What owners already do with it, easiest first.

Easy~10 minNo risk

Every Shelly answers on your network: turn the relay on, read the power draw, or have it publish to your MQTT broker. No account needed.

An evening~30 minNo risk

Gen2 and later devices run small JavaScript programs you write: timers, logic between devices, calls to any web service, all on the device.

An evening~30 minMay void the warranty

A community firmware, flashed over Wi-Fi, makes the relay show up in Apple Home without a bridge.

Hands-on~1 hCan brick it

Third-party firmware for the Gen4 line swaps Wi-Fi for Matter over Thread. Young project: read its device list first.
