Shelly PM Mini Gen3 vs Sonoff MINI Dry Wi-Fi Smart Switch

For control, the Sonoff MINI Dry, because it switches a circuit on and off with dry and wet contacts and works across Alexa, Google Home, HomeKit, SmartThings, Home Assistant, IFTTT and Matter. The Shelly PM Mini Gen3 only measures energy, so pick it purely for monitoring.

One switches, one measures. The Sonoff MINI Dry Wi-Fi Smart Switch is a switching relay with a physical button and broad integrations, while the Shelly PM Mini Gen3 is a monitoring-only device that reports consumption but cannot control a circuit.

The Sonoff MINI Dry Wi-Fi Smart Switch, clearly. It supports Matter, Apple HomeKit and IFTTT plus Alexa, Google Home, SmartThings and Home Assistant. The Shelly PM Mini Gen3 is a simpler meter that does not support Matter and offers a narrower integration list.

Buy the Shelly PM Mini Gen3 only if you want the cheapest way to monitor a single circuit's energy use and feed accurate readings into Home Assistant, with no need to switch that circuit on or off.

Buy the Sonoff MINI Dry if you want to actually control a circuit, such as a gate or garage door, with dry and wet contacts, a physical button and wide ecosystem support including Matter, HomeKit and IFTTT.
