Shelly 1 Gen3 vs Shelly PM Mini Gen3 comparison

Updated July 2026

Data from Amazon and official Shelly site.

2026 verdict

The Shelly 1 Gen3 wins this smart relay comparison because it actually switches circuits and connects more widely, adding Matter, Apple HomeKit and a broader integration set (Alexa, Google Home, SmartThings, Home Assistant) alongside its dry and wet contacts. The Shelly PM Mini Gen3 is a different tool: it is a dedicated energy monitor rather than a switch, so it measures a circuit's power, voltage and consumption but cannot turn anything on or off, and it is the more affordable, higher-rated unit for that narrow job. Both are tiny Shelly modules that run locally over Wi-Fi and Bluetooth and plug straight into Home Assistant. Choose the Shelly 1 Gen3 if you need remote control, automations and no-neutral wiring; choose the Shelly PM Mini Gen3 only when you want to measure an appliance's energy use and never switch it.

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

The Shelly 1 Gen3 is better overall for most buyers because it is a true smart relay that switches circuits and supports Matter, HomeKit and more platforms. The Shelly PM Mini Gen3 is a measurement-only power meter, so it wins only if your sole goal is monitoring energy on a circuit you do not need to control.

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

Switching versus measuring. The Shelly 1 Gen3 controls a circuit and can automate it, while the Shelly PM Mini Gen3 only measures power, voltage, current and consumption and cannot turn a load on or off.

Can the Shelly PM Mini Gen3 turn devices on and off like the Shelly 1 Gen3?

No. The Shelly PM Mini Gen3 is a power meter, not a switch, so it cannot control a load. The Shelly 1 Gen3 is a relay with dry and wet contacts that switches and automates the circuits it is wired into.

Do both integrate with Home Assistant?

Yes. Both feed into Home Assistant, but the Shelly 1 Gen3 also supports Matter, Apple HomeKit, Alexa, Google Home and SmartThings for control, while the Shelly PM Mini Gen3 is used mainly to push energy data into dashboards rather than to control anything.

Who should buy the Shelly 1 Gen3?

Buy the Shelly 1 Gen3 if you want to remotely switch and automate a circuit, especially in a no-neutral box, with Matter, HomeKit and dry-contact flexibility for garage doors, pumps and irrigation.

Who should buy the Shelly PM Mini Gen3?
