Shelly 1 Gen4 vs Sonoff MINI Dry Wi-Fi Smart Switch

Full Smart Relays comparison in 2026

Updated October 2026
Data from the official Shelly and Sonoff sites.
2026 verdict
Shelly or Sonoff? Between these two, the Shelly 1 Gen4 is the more capable smart relay, with Zigbee, Bluetooth, a 16A rating and a three-year warranty against one.
It adds Wi-Fi 6, Bluetooth 5.0 and Zigbee through a hub with router mode, switches inductive and capacitive loads and has overheating protection, while both relays offer dry and wet contacts, Matter and support for Alexa, Google Home, Apple Home, SmartThings and Home Assistant. The Sonoff MINI Dry Wi-Fi Smart Switch is the lower priced and better reviewed of the pair, with a physical on/off button the Shelly lacks, and owners like it for triggering gates and garage doors. Its limits are a 2A resistive rating, no inductive or capacitive loads and Wi-Fi only. Pick the Shelly 1 Gen4 for general-purpose switching, and the Sonoff MINI Dry Wi-Fi Smart Switch for a cheap, clean dry-contact trigger.

What the differences mean

Load rating

The Shelly 1 Gen4 switches up to 16A and handles resistive, inductive and capacitive loads. The Sonoff MINI Dry Wi-Fi Smart Switch is rated for 2A resistive only, with no inductive or capacitive loads, so it is a trigger for a motor controller or a small light rather than a switch for an appliance.

Radios

The Shelly 1 Gen4 offers Wi-Fi 6, Bluetooth 5.0 and Zigbee through a hub, where it also works as a Zigbee router. The Sonoff MINI Dry Wi-Fi Smart Switch is 2.4 GHz Wi-Fi only. Both support Matter.

Protection

The Shelly 1 Gen4 has overheating protection, the Sonoff MINI Dry Wi-Fi Smart Switch overcurrent protection. Neither lists overvoltage or overpower protection.

Physical button

The Sonoff MINI Dry Wi-Fi Smart Switch has an on/off button on the unit for manual control without the app. The Shelly 1 Gen4 has none, so it relies on the wall switch or the app.

Warranty

Shelly covers the 1 Gen4 for three years, against one year for the Sonoff MINI Dry Wi-Fi Smart Switch.

What owners say

Owners of both relays reach for them for the same job more often than any other: wiring the dry contact into a garage door opener or a gate so it can be triggered from the phone or by voice. Shelly 1 Gen4 owners single out local schedules that survive power cuts, reliable Home Assistant integration and uses beyond doors, such as pool heaters, pumps and low-voltage lights, while complaining that Zigbee pairing, with Hubitat especially, is fiddly and poorly documented and that it can be a tight fit in a switch box. Sonoff MINI Dry Wi-Fi Smart Switch owners like voice control through Alexa and Apple Home and the manual button, and their complaint is that the eWeLink app explains pulse mode poorly, with one reporting occasional disconnections.
