Alongside per-channel energy monitoring, it delivers a complete four-way safety suite (overheating, overvoltage, overcurrent, overpower), interlock/cover mode for roller shutters, curtains and garage doors, dry and wet contacts, and support for Alexa, Google Home, SmartThings and Home Assistant. The Shelly PM Mini Gen3 is the cheaper unit and a precise energy monitor, but it cannot switch a circuit on or off. Buy the Plus 2PM when you want to control (and meter) two circuits or automate shutters; reach for the PM Mini Gen3 only when standalone monitoring is all you need and price is the priority.

Frequently Asked Questions

Which is better overall: Shelly Plus 2PM or Shelly PM Mini Gen3?

The Shelly Plus 2PM, by a wide margin, because it controls two circuits, automates shutters and meters energy per channel. The Shelly PM Mini Gen3 only measures a circuit, so it makes sense only when you want monitoring without any switching.

What is the biggest difference between these two?

Control versus measurement. The Shelly Plus 2PM switches two circuits and adds cover mode and a four-way safety suite, while the Shelly PM Mini Gen3 is a monitoring-only device that tracks consumption but cannot turn a circuit on or off.

Which one can automate roller shutters?

The Shelly Plus 2PM. Its interlock/cover mode is built for roller shutters, curtains, awnings and garage doors, driving a motor up and down from one unit. The Shelly PM Mini Gen3 is an energy meter and cannot control any load.

Who should buy the Shelly Plus 2PM?

Buy the Shelly Plus 2PM if you want to control two circuits or roller shutters, monitor energy per channel and get a full four-way safety suite, all with proven, locally controllable Wi-Fi hardware.

Who should buy the Shelly PM Mini Gen3?

Buy the Shelly PM Mini Gen3 only if you want the cheapest way to monitor a single circuit's energy use and feed accurate readings into Home Assistant, with no need to switch that circuit.
