Shelly 1 Gen4 vs Shelly Plus 1

Full Smart Relays comparison in 2026

Updated September 2026
Data from Amazon and official Shelly site.
2026 verdict
On radios and platform support, the Shelly 1 Gen4 is the better relay of the two, the newer design of the same 16 A, single channel Shelly module.

It adds Matter, Apple Home and a Zigbee mode on top of Wi-Fi and Bluetooth, and it can act as a Zigbee router, none of which the Shelly Plus 1 offers. The Shelly Plus 1 keeps a longer track record, with a UL-listed build owners mention when they talk about electrical safety, and it is otherwise the same body: 37 x 42 x 16 mm, dry and wet contact modes, no energy monitoring and no overvoltage, overcurrent or overpower protection. Buy the Shelly 1 Gen4 for a new install, especially with Apple Home or Matter, and the Shelly Plus 1 only if a UL-listed unit for Alexa, Google Home or Home Assistant is what your inspector wants.

What the differences mean

Protocols

The Shelly 1 Gen4 offers 2.4 GHz Wi-Fi, Bluetooth and a Zigbee mode through a hub, and lists Matter. The Shelly Plus 1 is Wi-Fi only, with Bluetooth used just for pairing. If you run a Zigbee network, only the Gen4 can join it.

Apple Home and Matter

The Shelly 1 Gen4 lists Apple Home and Matter as supported. The Shelly Plus 1 lists both as not supported, so it stays out of the Apple Home app and away from Matter controllers.

Zigbee router

In Zigbee mode the Shelly 1 Gen4 repeats the signal for other devices, which helps a mesh reach a far corner. The Shelly Plus 1 has no Zigbee at all.

DC input

The Shelly 1 Gen4 takes 12 V or 24-48 V DC, while the Shelly Plus 1 is listed at 30 V and 10 A. For a low-voltage garden or pool light supply the Gen4 covers a wider range.

What has not changed

Both are 37 x 42 x 16 mm, both switch 16 A, both need a neutral wire and both have a 3 year warranty. Neither monitors energy or lists overvoltage, overcurrent or overpower protection, so this is not the reason to switch.

What owners say

Owners of both relays agree on the payoff: dry contact mode that triggers a garage door or gate without sending line voltage through the relay, and smooth Home Assistant integration. They also agree on the pain, a wiring diagram that is not obvious the first time and a snug fit in shallow boxes. Shelly 1 Gen4 owners single out local schedules that keep running through a power outage, setup over Wi-Fi that is easy, and a wider choice of protocols, while their extra complaint is Zigbee pairing that can be fiddly and thinly documented, Hubitat being the example they give. Shelly Plus 1 owners single out speed and reliability once configured, several comparing it favourably with Z-Wave switches, praise its UL-listed build and like configuring it locally over Bluetooth or its own access point without the cloud.

Upgrading from the Shelly Plus 1?

Moving from the Shelly Plus 1 to the Shelly 1 Gen4 changes the radios and the platforms, not the relay. You gain Zigbee, Matter and Apple Home support and a Zigbee router role, in the same 37 x 42 x 16 mm body with the same 16 A rating. If your Shelly Plus 1 already works with Alexa, Google Home or Home Assistant, there is nothing to fix, and it still has no energy monitoring or extra protections to gain on the newer model. Upgrade if you are moving to Apple Home, Matter or Zigbee.

Price history compared

Every price change of both, in the same store, so the gap between the two lines is what one costs more than the other.
