It closes a potential-free contact or drives low-voltage DC loads up to 24V and 2A, has overcurrent protection and a physical button, and works with Alexa, Google Home, Apple Home, SmartThings and Home Assistant. The Shelly PM Mini Gen3 is a power meter: it reads power, voltage, current and energy on a 110 to 240V circuit of up to 16A, but it has no relay and cannot turn anything on or off. It carries a three-year warranty against one, adds Bluetooth and costs less, though it has no Apple Home or Matter support. Pick the Sonoff MINI Dry Wi-Fi Smart Switch to automate a gate, garage door or boiler contact, and the Shelly PM Mini Gen3 to measure an appliance circuit you already control another way.

What the differences mean

Switching or measuring

The Sonoff MINI Dry Wi-Fi Smart Switch is a relay with dry and wet contact modes. The Shelly PM Mini Gen3 has no relay: it only meters the circuit it sits on, so it cannot switch a light or appliance.

What it connects to

The Shelly PM Mini Gen3 sits on a 110 to 240V AC circuit up to 16A. The Sonoff MINI Dry Wi-Fi Smart Switch must never switch AC: its output handles DC loads up to 24V and 2A, or a potential-free contact.

Platforms

The Sonoff MINI Dry Wi-Fi Smart Switch works with Alexa, Google Home, Apple Home, SmartThings, Home Assistant and Matter. The Shelly PM Mini Gen3 covers Alexa, Google Home, SmartThings and Home Assistant, without Apple Home or Matter.

Warranty and size

The Shelly PM Mini Gen3 comes with three years of warranty and a 29 x 34 x 16 mm body; the Sonoff is covered for one year and measures 43 x 41 x 21.5 mm.

What owners say

The two groups bought these modules for different reasons, and it shows. Shelly PM Mini Gen3 owners praise its accuracy on power, voltage, current and total energy, its small size, an immediate Home Assistant integration and its use as a gateway for Shelly BLU sensors; they warn that it measures but never switches, a point several found confusing, that the terminal block is small for heavier cable and that Shelly's naming led some to order the wrong model. Sonoff MINI Dry Wi-Fi Smart Switch owners wire its dry contact into gates and garage motors and report reliable pulse triggering, voice control through Alexa and Apple Home, and a handy manual button, while their complaints are thin eWeLink instructions for pulse mode and a single report of disconnections.

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.
