Shelly 1 Mini Gen4 vs Shelly 1PM Gen4 comparison

Updated July 2026

Data from Amazon and official Shelly site.

2026 verdict

The Shelly 1 Mini Gen4 takes this smart relay matchup as the more affordable option with a fuller listed safety picture, thanks to its confirmed overheating protection. Both are multi-protocol Gen4 modules sharing Wi-Fi, Bluetooth, Zigbee and Matter, dry and wet contacts, a Zigbee router role and support for Alexa, Google Home, Apple HomeKit, SmartThings and Home Assistant, so they are closely matched siblings. The Shelly 1PM Gen4 carries the higher owner rating and adds two things the Mini cannot match: built-in energy monitoring with precise power metering and a beefier 16A rating (versus 8A). Choose the Mini Gen4 to save money in the tightest boxes for lighter loads; step up to the 1PM Gen4 when you want to measure consumption or switch heavier circuits.

Frequently Asked Questions

Which is better overall: Shelly 1 Mini Gen4 or Shelly 1PM Gen4?

The Shelly 1 Mini Gen4 edges it here as the cheaper unit with a confirmed overheating-protection safety listing. That said, the 1PM Gen4 is the better buy if you specifically need energy monitoring or its higher 16A rating, as the Mini offers neither.

What is the main difference between these two Gen4 relays?

Metering and amperage. The Shelly 1PM Gen4 adds precise power metering (instant power, voltage and total consumption) and rates 16A, while the Shelly 1 Mini Gen4 has no energy monitoring and rates 8A. Their radios and platform support are otherwise the same multi-protocol Gen4 package.

Do both work with the same smart home platforms?

Yes. Both the Shelly 1 Mini Gen4 and Shelly 1PM Gen4 run Wi-Fi, Bluetooth, Zigbee and Matter, act as a Zigbee router, and integrate with Alexa, Google Home, Apple HomeKit, SmartThings and Home Assistant, all with full local control. The difference is metering and load, not ecosystem.

Who should buy the Shelly 1 Mini Gen4?

Buy the Shelly 1 Mini Gen4 if you want the cheaper module and the smallest possible footprint for light loads (up to 8A) in a crowded box, and you do not need power metering. It delivers the full Gen4 protocol stack in a tinier body.

Who should buy the Shelly 1PM Gen4?

Buy the Shelly 1PM Gen4 if you want to track a circuit's energy use or switch heavier loads up to 16A, for example a water heater, boiler or furnace. Its power metering and higher rating are the reasons to pay a little more.
