Shelly Plus 1 vs Shelly PM Mini Gen3 comparison

Updated July 2026

Data from Amazon and official Shelly site.

2026 verdict

Only one of these can turn something on, and that gives the Shelly Plus 1 the win on safety, integrations and both contact modes over the Shelly PM Mini Gen3. The Plus 1 is a 16A relay with dry and wet contact modes, DC switching up to 30V, documented overheating protection, a UL-listed build, SmartThings support and a 3-year warranty. The Shelly PM Mini Gen3 is cheaper and does the one thing the Plus 1 cannot: it meters a circuit precisely, reporting power, voltage, current and total consumption from a 13g body, and it works as a gateway for Shelly BLU Bluetooth devices. It has no relay, so it cannot switch the circuit it measures. Both need a neutral wire, both run on 2.4GHz Wi-Fi with Bluetooth, both work with Alexa, Google Home and Home Assistant, and neither supports Matter, HomeKit, Zigbee, Z-Wave or Thread. Choose the Shelly Plus 1 to control a load, the Shelly PM Mini Gen3 to measure one, or a Shelly Plus 1PM to do both.

Frequently Asked Questions

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

The Shelly Plus 1 wins overall because it can switch a circuit, with a 16A relay, dry and wet contact modes, DC support, overheating protection and SmartThings integration. The Shelly PM Mini Gen3 is cheaper and adds precise energy monitoring, but it has no relay of any kind.

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

Control versus measurement. The Shelly Plus 1 switches a load but reports nothing about it. The Shelly PM Mini Gen3 measures power, voltage, current and consumption but cannot switch the circuit at all. If you want both in one module, the Shelly Plus 1PM combines them.

Can the Shelly PM Mini Gen3 turn a circuit off?

No. It is a measurement-only module, designed to sit on a circuit and report exactly what it draws, which is useful on appliances that are not otherwise smart. Any switching has to come from a relay module such as the Shelly Plus 1 or a PM model.

Do both require a neutral wire?

Yes. The Shelly Plus 1 and the Shelly PM Mini Gen3 both need a neutral at the install point. Both are also 2.4GHz Wi-Fi only with Bluetooth, work with Alexa, Google Home and Home Assistant, and carry 3-year warranties.

Who should buy the Shelly Plus 1?

Buy the Shelly Plus 1 if you need to make an existing circuit smart, especially where a dry contact is required, such as a gate, boiler or garage controller. It handles 16A AC or 10A DC, is UL listed with overheating protection, and runs locally with no cloud account.

Who should buy the Shelly PM Mini Gen3?

Buy the Shelly PM Mini Gen3 if you want to find out what a circuit or appliance actually consumes without changing how it is switched. It is tiny, precise, quick to integrate with Home Assistant, doubles as a Shelly BLU gateway and comes with a 3-year warranty.
