Shelly 1PM Gen4 vs Sonoff ZBMINIR2 Extreme Zigbee Smart Switch comparison

Updated July 2026

Data from Amazon and official Shelly and Sonoff sites.

2026 verdict

Add power metering to the mix and the Shelly 1PM Gen4 comes out on top of this smart relay comparison, thanks to broader connectivity (Wi-Fi, Bluetooth, Zigbee and Matter versus the Sonoff ZBMINIR2 Extreme Zigbee Smart Switch's Zigbee-only radio), a fuller integrations list that adds Apple HomeKit and Matter, dry-contact wiring for garage doors and pumps, and instant power, voltage and consumption readings the Sonoff simply does not offer. The Sonoff ZBMINIR2 Extreme Zigbee Smart Switch answers with a more affordable price tag and settings that survive a power outage thanks to power-off memory, plus it slots straight into an existing Zigbee mesh without touching Wi-Fi. Both are single-channel relays that need a neutral wire. For anyone who wants to measure what a circuit draws while controlling it, or who wants the option to run over Wi-Fi, Bluetooth, Zigbee or Matter, the Shelly 1PM Gen4 is the stronger buy; pick the Sonoff only if you are building a pure Zigbee setup and do not need metering.

Frequently Asked Questions

Which is better overall: the Shelly 1PM Gen4 or the Sonoff ZBMINIR2 Extreme Zigbee Smart Switch?

The Shelly 1PM Gen4 wins this comparison, leading on connectivity, integrations and energy monitoring, while the Sonoff ZBMINIR2 Extreme Zigbee Smart Switch stays cheaper and keeps its state through power outages.

What is the biggest difference between the Shelly 1PM Gen4 and the Sonoff ZBMINIR2 Extreme Zigbee Smart Switch?
