Shelly 1 Gen3 vs Shelly Plus 2PM comparison

Updated June 2026

Data from Amazon and official Shelly site.

2026 verdict

Need one circuit or two? The Shelly Plus 2PM wins this smart relay comparison as a two-channel module with per-channel energy monitoring, a full safety suite (overheating, overvoltage, overcurrent and overpower protection) and a dedicated interlock/cover mode for roller shutters, curtains and garage doors, and it carries the higher owner rating. The single-channel Shelly 1 Gen3 still counters with genuine wins: it is the more affordable unit, it installs without a neutral wire (the Plus 2PM requires one), and it supports Matter and Apple HomeKit plus a broader integration set including Zigbee-free protocol via Wi-Fi and Bluetooth. Both share dry-contact and wet-contact wiring, hub-free local control and Home Assistant support. Go with the Shelly Plus 2PM for dual-circuit and shutter automation with metering; go with the Shelly 1 Gen3 for a cheaper, no-neutral single-circuit retrofit that keeps Matter and HomeKit.

Frequently Asked Questions

Which is better overall: Shelly 1 Gen3 or Shelly Plus 2PM?

The Shelly Plus 2PM is better overall, offering two channels, per-channel energy monitoring, a full protection suite and a cover mode for shutters, plus a higher owner rating. The Shelly 1 Gen3 wins when you only need one channel, lack a neutral wire, want Matter and HomeKit, or want to spend less.

What is the biggest difference between the Shelly 1 Gen3 and the Shelly Plus 2PM?

Channels and platform support. The Plus 2PM controls two circuits, meters each channel and drives roller shutters via cover mode, but works over Wi-Fi and Bluetooth only, with no Matter or HomeKit. The Gen3 is single-channel with no metering, yet installs without a neutral and adds Matter and Apple HomeKit.

Does the Shelly 1 Gen3 support platforms the Shelly Plus 2PM does not?

Yes. The Shelly 1 Gen3 supports Matter and Apple HomeKit, which the Shelly Plus 2PM lacks. The Plus 2PM works with Google Home, Alexa, SmartThings and Home Assistant over Wi-Fi and Bluetooth but has no Matter or HomeKit path.

Which relay is better for roller shutters?

The Shelly Plus 2PM. Its dedicated interlock/cover mode drives shutters, curtains, awnings and gates up and down from one unit. The single-channel Shelly 1 Gen3 has no cover mode, so it is not built for that job.

Who should buy the Shelly 1 Gen3?

Buy the Shelly 1 Gen3 if you need one channel, have no neutral wire, want Matter or Apple HomeKit, or want the cheaper module. Its dry and wet contacts suit garage doors, pumps and irrigation.

Who should buy the Shelly Plus 2PM?

Buy the Shelly Plus 2PM if you want to control two circuits or automate roller shutters and garage doors, value per-channel energy monitoring and full protection, and have a live and neutral wire at the install point.
