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.
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.
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.
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.
The Shelly Plus 2PM has a dedicated cover mode with interlocked outputs.
The Shelly PM Mini Gen3 is a smaller, cheaper meter that does exactly that.
The Shelly Plus 2PM has two relay channels; the PM Mini Gen3 has none.
The Shelly PM Mini Gen3 is the smaller module, though it only measures.
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.
The Shelly Plus 2PM, because it switches two circuits, meters each one and protects against overload. The Shelly PM Mini Gen3 is a power meter only and suits jobs where nothing needs switching.
The Shelly Plus 2PM is a two-channel relay with metering, while the Shelly PM Mini Gen3 is a meter with no relay at all.
No. The Shelly PM Mini Gen3 cannot switch anything. For shutters, blinds or gates, the Shelly Plus 2PM has a cover mode with interlocked outputs.
No. Neither the Shelly Plus 2PM nor the Shelly PM Mini Gen3 supports Apple Home or Matter; both work with Alexa, Google Home, SmartThings and Home Assistant.
Anyone automating shutters or two lighting circuits who wants per-channel metering and full electrical protection in one module.
Home Assistant users who want to meter an appliance or a separate power line accurately in a tiny module, without switching it.
