Category: Relay Switches
The Shelly 1PM Gen3 x4 is a convenient 4-pack of Gen3 relay switches designed for smart home and automation projects.
The 4-pack makes wiring up my whole automation project a one-order job, and the form factor is compact enough to tuck behind a light switch. Gen3 feels snappier than my older units when toggling over Wi-Fi, and the option to add a couple more later is nice since they're sold individually.
The power monitoring on these Gen3 relays is spot-on—I can see exactly what each device is drawing right from the app, and having four units in one box saved me a second trip to the store. Setup was straightforward with the existing wiring, and they’ve been rock-solid for the past couple weeks.
Swapped out the old dumb switches in my hallway and ran four lights off these in one afternoon. The energy monitoring on each unit is spot on, and they pair with Home Assistant in under two minutes.
