Shelly 2PM Gen3 vs Sonoff ZBMINIR2 Extreme Zigbee Smart Switch comparison

Updated July 2026

Data from Amazon and official Shelly and Sonoff sites.

2026 verdict

The Sonoff ZBMINIR2 Extreme Zigbee Smart Switch pulls out the win in this smart relay comparison against the Shelly 2PM Gen3, mostly on value and its role as a mesh-extending Zigbee router, with power-off memory and wet-contact wiring also going its way. That said, the two are built for different jobs: the Shelly 2PM Gen3 is a dual-channel Wi-Fi and Matter relay designed for roller shutters, blinds and garage doors through its interlock mode, and it backs that up with per-channel energy monitoring that the single-channel Sonoff cannot match. If you need to drive two circuits or automate a motorized cover, the Shelly 2PM Gen3 is simply built for that job and the Sonoff is not a real substitute. But for switching one basic circuit inside an existing Zigbee network, extending mesh coverage, and keeping the last on or off state through outages, the Sonoff ZBMINIR2 Extreme Zigbee Smart Switch is the more sensible and cheaper pick.
