Shelly 1 Gen3 vs Sonoff MINI Dry Wi-Fi Smart Switch

The Sonoff MINI Dry Wi-Fi Smart Switch takes the overall edge as the cheaper, higher-rated relay with a wider integration list (including IFTTT), a physical button and overcurrent protection. The Shelly 1 Gen3 is the better switch for heavier loads, DC power or no-neutral installs thanks to its 16A rating.

Load capacity. The Shelly 1 Gen3 is rated 16A and installs without a neutral, while the Sonoff MINI Dry is rated 2A and needs a neutral in AC input mode. The Sonoff adds a physical on/off button and IFTTT support the Shelly lacks.

The Shelly 1 Gen3, by a wide margin. It is rated 16A and switches resistive and DC loads, whereas the Sonoff MINI Dry Wi-Fi Smart Switch is rated 2A and is aimed at light dry-contact triggers like garage doors and gates rather than high-current circuits.

The Sonoff MINI Dry does. It includes a physical on/off button for manual, app-free control and supports IFTTT along with Matter and the major voice platforms. The Shelly 1 Gen3 has no built-in on/off button and does not list IFTTT.

Buy the Shelly 1 Gen3 if you need to switch heavier loads up to 16A, want AC or DC power flexibility, need a no-neutral install, or want on-device scripting. Its higher rating makes it the more capable switch of the two.

Buy the Sonoff MINI Dry Wi-Fi Smart Switch if you want a cheap, well-rated dry-contact relay for a garage door or gate, value a physical on/off button and IFTTT, and your load stays within its 2A rating.
