Shelly 1 Mini Gen3 vs Sonoff ZBMINIR2 Extreme Zigbee Smart Switch

The two trade blows here, but the Sonoff ZBMINIR2 Extreme Zigbee Smart Switch narrowly wins this smart relay pairing, backed by a higher maximum resistive load, a typically lower price, power-off memory, and its extra job as a Zigbee router. The Shelly 1 Mini Gen3 fires back hard: it wins on connectivity by adding Bluetooth alongside Wi-Fi, holds a 3-year warranty triple the Sonoff's coverage, includes dry-contact wiring for garage doors and sprinklers that the Sonoff lacks, and needs no Zigbee bridge to get started since it talks Wi-Fi directly. Neither model measures energy consumption, and both require a neutral wire. Buyers who want a plug-and-play Wi-Fi relay with a long warranty and dry-contact flexibility should lean toward the Shelly 1 Mini Gen3; those already running a Zigbee mesh who want more load headroom and a mesh-extending router node will get more from the Sonoff ZBMINIR2 Extreme Zigbee Smart Switch.
