2026 verdict
If the job is switching a light or a shutter, the Shelly Plus 2PM is the one to buy, since the Shelly PM Mini Gen3 only meters its circuit.
The Shelly Plus 2PM has two relay channels with metering on each, a cover mode for roller shutters, blinds and gates, and full overheating, overvoltage, overcurrent and overpower protection. The Shelly PM Mini Gen3 is the cheaper and smaller module, 29 x 34 x 16 mm against 37 x 42 x 16 mm, and reads power, voltage, current and energy on a 16A circuit, but it has no relay and no electrical protection. They share a lot: Wi-Fi and Bluetooth, a three-year warranty, Alexa, Google Home, SmartThings and Home Assistant, and neither supports Apple Home or Matter. Choose the Shelly Plus 2PM to control and meter two circuits or a shutter, and the Shelly PM Mini Gen3 to measure a circuit you do not need to switch.

What the differences mean
Switching
The Shelly Plus 2PM switches two separate circuits or drives one shutter motor. The Shelly PM Mini Gen3 has no relay, so it can report what a circuit uses but never turn it on or off.
Protection
The Shelly Plus 2PM cuts out on overheating, overvoltage, overcurrent and overpower. The Shelly PM Mini Gen3 has none of those protections, which matters less for a device that switches nothing.
Metering
Both measure energy. The Shelly Plus 2PM meters each of its two channels; the Shelly PM Mini Gen3 meters one circuit of up to 16A and 3840W.
Size
At 29 x 34 x 16 mm and 13 g, the Shelly PM Mini Gen3 hides in almost any box. The Shelly Plus 2PM is 37 x 42 x 16 mm, still compact for a dual relay.
Which one to buy if
- you are automating roller shutters or blinds
The Shelly Plus 2PM has a dedicated cover mode with interlocked outputs.
- you only want to measure a circuit
The Shelly PM Mini Gen3 is a smaller, cheaper meter that does exactly that.
- you want to control two lights from one box
The Shelly Plus 2PM has two relay channels; the PM Mini Gen3 has none.
- the back box is very shallow or crowded
The Shelly PM Mini Gen3 is the smaller module, though it only measures.

What owners say
Owners of both Shelly modules praise the same local Home Assistant integration, quick and reliable without a cloud account. Shelly Plus 2PM owners, many with several Shelly devices already, describe years of use without failure and single out the cover mode that turns an ordinary switch into up, down and position control for shutters, plus metering on each channel; they note it needs live and neutral, can run warm and gives no position feedback without another sensor. Shelly PM Mini Gen3 owners focus on the accuracy of its power, voltage and energy readings, its small size and its role as a gateway for Shelly BLU sensors, and they warn that it does not switch anything, that the terminal block is small for heavier cable and that Shelly's naming led some to order the wrong model.
