Shelly 2PM Gen4 vs Shelly Plus 2PM comparison

Updated July 2026

Data from Amazon and official Shelly site.

2026 verdict

The Shelly Plus 2PM wins this smart relay comparison as the more affordable dual-channel unit, and it confirms both dry-contact and wet-contact modes for flexible wiring. These two are close cousins: both are two-channel relays with per-channel energy monitoring, a complete four-way safety suite (overheating, overvoltage, overcurrent, overpower), interlock/cover mode for roller shutters, and support for Alexa, Google Home, SmartThings and Home Assistant. The Shelly 2PM Gen4 is the newer, more connected model, adding Zigbee and Matter with a Zigbee router role and Apple HomeKit, plus a higher 16A rating (versus 10A). Choose the Plus 2PM to save money on Wi-Fi-based shutter and dual-circuit control; step up to the 2PM Gen4 if you want Matter, Zigbee routing or heavier loads.

Frequently Asked Questions

Which is better overall: Shelly 2PM Gen4 or Shelly Plus 2PM?

The Shelly Plus 2PM wins on value and confirmed dry and wet contact modes, making it a strong Wi-Fi pick for shutters and dual circuits. The Shelly 2PM Gen4 is the better choice if you want Zigbee, Matter, HomeKit or its higher 16A rating.

Connectivity and load. The 2PM Gen4 adds Zigbee, Matter, HomeKit and a Zigbee router role and rates 16A, while the Plus 2PM sticks to Wi-Fi and Bluetooth and rates 10A. Their two-channel design, energy monitoring, cover mode and safety suite are otherwise very similar.

Yes. Both the Shelly 2PM Gen4 and Shelly Plus 2PM offer interlock/cover mode for roller shutters and blinds, per-channel energy monitoring and a four-way safety suite. The Gen4 simply adds newer radios like Zigbee and Matter on top.

Who should buy the Shelly Plus 2PM?

Buy the Shelly Plus 2PM if you want proven dual-circuit and shutter automation over Wi-Fi at a lower price, with per-channel energy monitoring and full safety protection, and you do not need Matter, Zigbee or a 16A rating.
