Shelly 2PM Gen4 vs Sonoff MINI Dry Wi-Fi Smart Switch comparison

Updated July 2026

Data from Amazon and official Shelly and Sonoff sites.

2026 verdict

The Shelly 2PM Gen4 wins this smart relay comparison as the far more capable module, with a longer 3-year warranty (versus 1 year), a complete four-way safety suite (overheating, overvoltage, overcurrent, overpower), built-in energy monitoring, two 16A channels and Bluetooth plus Zigbee radios with a Zigbee router role. The Sonoff MINI Dry Wi-Fi Smart Switch is the cheaper, higher-rated pick and adds IFTTT to its integrations along with confirmed dry-contact and wet-contact modes and a physical button, but it is a single-channel relay rated at just 2A. Both work with Matter, Alexa, Google Home, Apple HomeKit, SmartThings and Home Assistant. Choose the 2PM Gen4 for dual-circuit control, shutter automation, metering and heavier loads; pick the Sonoff MINI Dry for a cheap, simple single-load trigger.

Frequently Asked Questions

Which is the better relay, the Shelly 2PM Gen4 or the Sonoff MINI Dry Wi-Fi Smart Switch?

The Shelly 2PM Gen4 wins overall with two 16A channels, energy monitoring, cover mode, a four-way safety suite and a 3-year warranty. The Sonoff MINI Dry is the value pick, cheaper and higher-rated with IFTTT, but it is a single-channel 2A relay.

What is the biggest difference between them?

Scale and safety. The Shelly 2PM Gen4 is a dual-channel 16A relay with full safety protection, energy monitoring and Zigbee routing, while the Sonoff MINI Dry is a single-channel 2A trigger with only overcurrent protection. They suit very different loads.

Which one can control roller shutters or two circuits?

The Shelly 2PM Gen4. Its two channels and interlock/cover mode handle roller shutters, blinds and dual light circuits. The Sonoff MINI Dry Wi-Fi Smart Switch has a single channel and is built for triggering one circuit, such as a gate or garage door.

Who should buy the Shelly 2PM Gen4?

Buy the Shelly 2PM Gen4 if you need to control two circuits or roller shutters, want per-channel energy monitoring and a full four-way safety suite, and value Zigbee, Matter and a 16A rating with a longer warranty.

Who should buy the Sonoff MINI Dry Wi-Fi Smart Switch?

Buy the Sonoff MINI Dry if you want the cheapest, best-reviewed way to trigger a single gate or garage door, value IFTTT and a physical button, and your load stays within its 2A limit.
