2026 verdict
Shelly 1 Mini Gen3 is the better pick of these two Shelly minis for anyone who wants to control a circuit, because it is a relay and the other is not.
It switches 8A with dry and wet contact modes, lists overheating protection, and supports Matter and Apple Home alongside Alexa, Google Home, SmartThings and Home Assistant. The Shelly PM Mini Gen3 is the lower priced and better rated of the pair, but it only measures: power, voltage, current and consumption on one circuit rated up to 16A, with full Bluetooth that doubles as a gateway for Shelly BLU sensors, and no Matter or Apple Home. They share almost the same 29 mm footprint, a neutral wire requirement and a 3-year warranty. Choose the Shelly 1 Mini Gen3 to make a light or appliance smart, and the Shelly PM Mini Gen3 to watch what a circuit uses while its own switch stays in charge.

What the differences mean
Relay or meter
The Shelly 1 Mini Gen3 turns its circuit on and off. The Shelly PM Mini Gen3 has no relay: it only reports what the circuit draws, so pairing it with an existing switch is the point, not a limitation you can work around.
Matter and Apple Home
The Shelly 1 Mini Gen3 supports Matter and appears in Apple Home. The Shelly PM Mini Gen3 supports neither, though it reaches Alexa, Google Home, SmartThings and Home Assistant.
Bluetooth
The Shelly PM Mini Gen3 keeps full Bluetooth and works as a gateway for Shelly BLU sensors. The Shelly 1 Mini Gen3 uses Bluetooth only for pairing.
Size
At 29 x 35 x 16 mm and 29 x 34 x 16 mm, the two are practically the same size, so whichever you choose fits the same boxes.

What owners say
Owners of both minis praise how small they are and how easily they disappear into a box, and both groups mention the paperwork: Shelly 1 Mini Gen3 owners about a misleading wiring diagram, Shelly PM Mini Gen3 owners about naming that led them to order the wrong model. Shelly 1 Mini Gen3 owners focus on control, garage doors, sprinklers, fireplaces and shutters switched locally with no lag through a built-in web page. Shelly PM Mini Gen3 owners focus on measurement, precise readings on washing machines, dryers and caravan hookups flowing straight into Home Assistant, and their warning is that it does not switch anything and its terminals suit lighter cables.
