Shelly 1 Mini Gen4 vs Sonoff ZBMINIR2 Extreme Zigbee Smart Switch

For most buyers, the Shelly 1 Mini Gen4 is the better smart relay, because it pairs a similarly tiny footprint with real protocol choice (Wi-Fi, Bluetooth, Zigbee and Matter) that the Sonoff ZBMINIR2 Extreme Zigbee Smart Switch cannot match, since the Sonoff speaks Zigbee only and needs a Zigbee bridge before it does anything. The Shelly 1 Mini Gen4 backs that up with a fuller integrations list (Apple HomeKit and Matter alongside Alexa, Google and SmartThings), confirmed overheating protection, dry-contact wiring for garage doors and pumps, and a 3-year warranty against the Sonoff's 1-year coverage. The Sonoff ZBMINIR2 Extreme Zigbee Smart Switch counters with a higher maximum resistive load and settings that survive a power cut thanks to power-off memory, and it stays the more sensible pick for anyone already committed to a Zigbee mesh with no interest in Wi-Fi. Both need a neutral wire and skip energy monitoring entirely, so pick the Shelly 1 Mini Gen4 for connectivity flexibility and platform breadth, and the Sonoff only if your home is Zigbee-first and you need the extra headroom on current.
