2026 verdict
The Shelly Plus 2PM takes this two-channel relay matchup as the lower priced of the pair, with its dry and wet contact modes and a 3-year warranty on record.
It shares almost everything with its successor, the Shelly 2PM Gen3: two channels, interlock mode for shutters and garage doors, per-channel energy monitoring, the full set of overheating, overvoltage, overcurrent and overpower protections, and the same 37 x 42 x 16 mm body. What the Shelly 2PM Gen3 adds is Matter, which brings Apple Home into the list, a 16A rating per channel against 10A, and full Bluetooth rather than Bluetooth for pairing. Choose the Shelly Plus 2PM for shutters, blinds and dual light circuits on Alexa, Google Home or Home Assistant, and the Shelly 2PM Gen3 if your home runs on Apple Home or Matter, or the loads are heavier.

What the differences mean
Matter and Apple Home
The Shelly 2PM Gen3 supports Matter and, through it, Apple Home. The Shelly Plus 2PM has neither, so on an iPhone-centred home only the Gen3 shows up in the Home app; on Alexa, Google Home, SmartThings and Home Assistant both work.
Load rating
The Shelly 2PM Gen3 is rated 16A per channel, the Shelly Plus 2PM 10A. For shutter motors and lighting circuits either is plenty; the gap only matters on heavier loads like heaters or pumps.
Contact modes
The Shelly Plus 2PM documents both dry and wet contact modes. The Shelly 2PM Gen3 does not document either, so if a dry contact is the reason you are buying, the Plus is the one with it on paper.
Bluetooth
The Shelly 2PM Gen3 keeps full Bluetooth, while the Shelly Plus 2PM uses it for pairing only. For most installs this changes setup, not daily use.
Which one to buy if
- your home runs on Apple Home
The Shelly 2PM Gen3 joins Apple Home through Matter, and the Shelly Plus 2PM supports neither.
- you are automating roller shutters on Home Assistant
The Shelly Plus 2PM has the same interlock mode and metering as the newer model at the lower price, and owners report years of reliable local use.
- each channel drives a heavy load
At 16A per channel against 10A, the Shelly 2PM Gen3 leaves more headroom.
- you need a dry contact for a garage door or gate
The Shelly Plus 2PM documents dry contact mode, which the Shelly 2PM Gen3 spec sheet does not.

What owners say
Owners of both Shelly relays buy them for the same jobs, roller shutters, blinds and garage doors driven from an existing switch, and both groups praise how dependable they are once running. Shelly Plus 2PM owners talk about trust built over years and several units, a cover mode that turns a plain switch into precise position control, and running everything locally through Home Assistant with no cloud account; their complaints are the neutral wire older UK boxes lack, units that run warm and no position feedback without an extra sensor. Shelly 2PM Gen3 owners single out a Wi-Fi link that holds deep inside the wall box and per-channel metering that replaced pricier shutter actuators, while a minority describe a frustrating first pairing, trouble adding it to Alexa and a body slightly thicker than the previous generation.
Upgrading from the Shelly Plus 2PM?
Moving up from the Shelly Plus 2PM to the Shelly 2PM Gen3 buys Matter support, Apple Home, full Bluetooth and a 16A rating per channel instead of 10A. The two channels, interlock mode, energy monitoring, protections and body size stay the same. If your Shelly Plus 2PM already runs your shutters on Alexa, Google Home or Home Assistant, there is little to gain; the Shelly 2PM Gen3 is worth it when you want the relay in Apple Home or need the extra current.
