2026 verdict
For roller shutters or a switch box that feeds two circuits, the Shelly Plus 2PM is the stronger smart relay of this pair.
It switches two channels from one module, meters energy on each of them, adds a dedicated interlock mode for covers and carries the full set of overheating, overvoltage, overcurrent and overpower cutoffs, where the smaller module only has overheating protection. The Shelly 1 Mini Gen4 answers with a much wider reach: native Apple HomeKit and Matter support that the Plus 2PM lacks, a Zigbee radio that also works as a mesh router, and a dry contact mode for garage doors, gates and boilers, all in a 29 x 34 mm body. Both need a neutral wire and both carry a 3-year warranty. Choose the Shelly Plus 2PM for shutters, blinds and two metered circuits on Wi-Fi, and the Shelly 1 Mini Gen4 for a single light or a dry contact job in a cramped box, especially in an Apple Home or Zigbee home.

What the differences mean
Number of channels
The Shelly Plus 2PM controls two circuits, or one motorised cover in interlock mode, from a single module. The Shelly 1 Mini Gen4 switches one circuit, so two lights mean two modules and two spots behind the wall.
Energy monitoring
The Shelly Plus 2PM measures consumption on each channel, handy for seeing what a heater or a pump really draws. The Shelly 1 Mini Gen4 has no metering at all, it only switches.
Smart home platforms
The Shelly 1 Mini Gen4 works with Apple HomeKit and Matter natively, alongside Alexa, Google Home, SmartThings and Home Assistant. The Shelly Plus 2PM covers Alexa, Google Home, SmartThings and Home Assistant but not Apple Home or Matter, which rules it out for an Apple household without a bridge.
Radios
Both run on 2.4 GHz Wi-Fi with Bluetooth. The Shelly 1 Mini Gen4 can also join a Zigbee network through a Zigbee hub and then acts as a router that strengthens the mesh; the Shelly Plus 2PM has no Zigbee radio.
Protection
The Shelly Plus 2PM cuts out on overheating, overvoltage, overcurrent and overpower. The Shelly 1 Mini Gen4 only has overheating protection, so the wiring and the load have to stay inside its 8A rating on their own.
Size
At 29 x 34 x 16 mm and 19g, the Shelly 1 Mini Gen4 fits boxes that are already crowded with wires. The Shelly Plus 2PM measures 37 x 42 x 16 mm, still compact for two channels but harder to squeeze into a shallow fixture box.
Which one to buy if
- you are automating roller shutters, blinds or curtains
The Shelly Plus 2PM has a dedicated interlock mode for covers, which the Shelly 1 Mini Gen4 does not offer.
- your home runs on Apple Home or Matter
The Shelly 1 Mini Gen4 supports Apple HomeKit and Matter natively, and the Shelly Plus 2PM supports neither.
- you want to see how much power two circuits draw
Only the Shelly Plus 2PM meters energy, and it does it separately on each channel.
- you need a dry contact for a garage door opener or a boiler
The Shelly 1 Mini Gen4 offers a dry contact mode; the Shelly Plus 2PM switches powered loads only.
- you run a Zigbee network and want every mains device to extend it
Paired to a Zigbee hub, the Shelly 1 Mini Gen4 acts as a Zigbee router; the Shelly Plus 2PM is Wi-Fi only.

What owners say
Owners of both Shelly modules praise the same local control: each can be run straight from Home Assistant without leaning on the cloud, and both groups name the live plus neutral requirement as the thing to check before buying. Past that, they talk about different projects. Shelly Plus 2PM owners describe years of trouble-free use across many units and single out the cover mode that turns a plain wall switch into up, down and position control for shutters and curtains, while a few mention the module running warm and no built-in feedback on whether a shutter is fully closed. Shelly 1 Mini Gen4 owners lead with its size, fitting it behind switches and inside fixtures where nothing else fits, and with dry contact projects such as garage doors and pool lights, and they complain about tiny printed instructions and a few units that died or dropped off the network after months.
Frequently Asked Questions
Which is better overall: Shelly 1 Mini Gen4 or Shelly Plus 2PM?
The Shelly Plus 2PM, for most installs. It switches two circuits, meters energy on each, handles shutters in interlock mode and carries full overheating, overvoltage, overcurrent and overpower protection. The Shelly 1 Mini Gen4 is the better pick for Apple Home, Matter or Zigbee households and for dry contact jobs in a tight box.
What is the difference between the Shelly 1 and the Shelly 2 in this comparison?
The number is the channel count. The Shelly 1 Mini Gen4 switches one circuit, while the Shelly Plus 2PM switches two, or drives one shutter or blind motor in interlock mode. The PM in Shelly Plus 2PM stands for power metering, which the Shelly 1 Mini Gen4 does not have.
Does the Shelly Plus 2PM work with Apple Home?
No. The Shelly Plus 2PM supports Alexa, Google Home, SmartThings and Home Assistant but not Apple HomeKit or Matter. The Shelly 1 Mini Gen4 supports both Apple HomeKit and Matter, along with the same other platforms.
Do the Shelly 1 Mini Gen4 and the Shelly Plus 2PM need a neutral wire?
Yes, both do. The Shelly 1 Mini Gen4 and the Shelly Plus 2PM each need live and neutral at the install point, so check the switch box before buying either.
Who should buy the Shelly 1 Mini Gen4?
Anyone who needs to make one light or appliance smart in a crowded switch or fixture box, wants a dry contact for a garage door or boiler, or runs Apple Home, Matter or a Zigbee network, and does not need energy monitoring.
Who should buy the Shelly Plus 2PM?
Homes automating roller shutters, blinds, curtains or two lighting circuits from one switch position, especially Home Assistant users who want per-channel energy monitoring and full electrical protection on Wi-Fi.
