2026 verdict
Shelly 2PM Gen3 wins over the Shelly 1 Mini Gen3 as the better rated and more capable Gen3 relay, with two metered channels and full overload protection.
It switches 16A per channel against 8A, drives roller shutters, blinds and garage doors in interlock mode, and cuts power on overheating, overvoltage, overcurrent and overpower. The Shelly 1 Mini Gen3 is the lower priced single-channel relay and much smaller, 29 x 35 x 16 mm and 19 g against 37 x 42 x 16 mm and 30 g, with dry and wet contact modes documented for trigger jobs, but no metering. Both need a neutral, stay on Wi-Fi with no Zigbee and work with Alexa, Google Home, Apple Home through Matter, SmartThings and Home Assistant. Choose the Shelly 2PM Gen3 for shutters or two circuits, and the Shelly 1 Mini Gen3 for one light in a tight box.

What the differences mean
Channels and covers
The Shelly 2PM Gen3 has two channels and an interlock mode that drives a motor up and down, which is what shutters and garage doors need. The Shelly 1 Mini Gen3 switches one circuit.
Energy monitoring
The Shelly 2PM Gen3 measures consumption on each channel. The Shelly 1 Mini Gen3 has no metering.
Size
The Shelly 1 Mini Gen3 is 29 x 35 x 16 mm and 19 g, the Shelly 2PM Gen3 37 x 42 x 16 mm and 30 g. Behind a switch in a shallow or crowded box, the Mini is far easier to fit.
Load and protection
The Shelly 2PM Gen3 is rated 16A per channel with overheating, overvoltage, overcurrent and overpower protection. The Shelly 1 Mini Gen3 is rated 8A with overheating protection only, which is fine for lighting.
Which one to buy if
- you are motorizing shutters, blinds or a garage door
The Shelly 2PM Gen3's interlock mode is built for covers.
- one box controls two lights
Two metered channels mean one Shelly 2PM Gen3 replaces two single relays.
- you are adding one smart light in a tight box
The Shelly 1 Mini Gen3 is much smaller and costs less.
- you need a dry contact for a sprinkler or fireplace
The Shelly 1 Mini Gen3 documents dry contact mode, which the 2PM spec sheet does not.

What owners say
Owners of both Shelly Gen3 relays praise reliable local control and quick Home Assistant integration. Shelly 2PM Gen3 owners use it on roller shutters, blinds and garage doors, highlight a Wi-Fi link that holds deep inside the wall box and per-channel metering that replaced pricier actuators, and a minority mention a frustrating first pairing, trouble adding it to Alexa and a body slightly thicker than before. Shelly 1 Mini Gen3 owners dwell on value and size, installs that take minutes and a built-in web page that makes the app optional, using it for sprinklers, fireplaces and garage doors; their recurring complaint is a misleading wiring diagram that sends first-timers to YouTube.
