Shelly 2PM Gen4 vs Shelly Plus 1 comparison

Updated July 2026

Data from Amazon and official Shelly site.

2026 verdict

More channels, more protection, less money: the Shelly 2PM Gen4 beats the Shelly Plus 1 on price, safety, integrations, energy monitoring and Zigbee routing. It switches two independent 16A circuits instead of one, meters each of them, adds cover mode with obstacle detection for shutters and blinds, guards against overheating, overvoltage, overcurrent and overpower, and connects over Wi-Fi, Bluetooth or Zigbee with Matter, Apple HomeKit and SmartThings support. The Shelly Plus 1 keeps two advantages that decide certain installs: dry and wet contact modes, so it can isolate the relay for a gate controller or boiler input, and low-voltage DC switching up to 30V. Both need a neutral wire, both carry 3-year warranties, both are the same 37 x 42 x 16 mm size and both run locally with Home Assistant. Choose the Shelly 2PM Gen4 for almost every mains job, and the Shelly Plus 1 when the wiring calls for a dry contact or a DC circuit.

Frequently Asked Questions

Which is better overall: Shelly 2PM Gen4 or Shelly Plus 1?

The Shelly 2PM Gen4 wins overall. It costs less, controls two 16A channels rather than one, meters both, adds full overheating, overvoltage, overcurrent and overpower protection, and supports Zigbee, Matter, Apple HomeKit and SmartThings. The Shelly Plus 1 wins only on dry contact modes and DC switching.

What is the biggest difference between the Shelly 2PM Gen4 and the Shelly Plus 1?

Capability per module. The Shelly 2PM Gen4 is a dual-channel metering relay with cover mode, a protection suite and Zigbee plus Matter support. The Shelly Plus 1 is a single-channel relay with no metering and no Matter, but it can isolate its contacts and switch a 30V DC load.

Which one should I use for a garage door or gate controller?

The Shelly Plus 1, if the controller expects a volt-free input, because it offers a true dry contact mode. The Shelly 2PM Gen4 does not, so it is better suited to mains loads such as lights, sockets and shutter motors, where its interlock and metering features shine.

Do both work with Apple HomeKit?

No. Only the Shelly 2PM Gen4 supports Apple HomeKit and Matter, alongside Alexa, Google Home, SmartThings and Home Assistant. The Shelly Plus 1 has no HomeKit or Matter support and appears in the Apple Home app only through a bridge such as Home Assistant.

Who should buy the Shelly 2PM Gen4?

Buy the Shelly 2PM Gen4 if you want two independent 16A channels with per-channel consumption data, shutter control with obstacle detection, a complete protection set and the choice of Wi-Fi or Zigbee with Matter and HomeKit. It needs a neutral wire and carries a 3-year warranty.

Who should buy the Shelly Plus 1?

Buy the Shelly Plus 1 when the install needs isolated dry contacts, for a gate, boiler or doorbell circuit, or when you are switching a low-voltage DC load up to 30V. It is UL listed, lists overheating protection and comes with a 3-year warranty.
