Shelly 2PM Gen3 vs Sonoff MINI Dry Wi-Fi Smart Switch

The Sonoff MINI Dry Wi-Fi Smart Switch wins this pairing for a single circuit, with the widest integrations (adding IFTTT alongside Alexa, Google Home, HomeKit, SmartThings, Home Assistant and Matter), a lower price and confirmed dry and wet contacts. The Shelly 2PM Gen3 is the better choice when you need two channels, higher current or energy monitoring.

Channels and current. The Sonoff MINI Dry Wi-Fi Smart Switch is a single-channel relay rated 2A built for dry-contact triggering, while the Shelly 2PM Gen3 is a two-channel relay rated 16A with per-channel energy monitoring and an interlock/cover mode for shutters.

The Sonoff MINI Dry Wi-Fi Smart Switch is purpose-built for this, using dry contact mode to send a clean pulse into a garage door opener or gate motor. The Shelly 2PM Gen3 can switch circuits too, but it is geared toward two circuits and cover automation rather than a single pulse trigger.

The Shelly 2PM Gen3 includes built-in per-channel power metering. The Sonoff MINI Dry Wi-Fi Smart Switch does not offer energy monitoring, so pick the Shelly if tracking consumption matters.

Budget-conscious buyers who need to automate one pulse-triggered circuit, like a gate or garage door, with broad ecosystem support including IFTTT, Apple HomeKit and Matter, plus a physical on/off button for manual control.

Anyone who needs to control two circuits or a roller shutter, wants a higher 16A current rating, or wants per-channel energy monitoring over Wi-Fi and Matter. The Shelly 2PM Gen3 requires a neutral wire at the install point.
