Shelly 2PM Gen4 vs Sonoff ZBMINIR2 Extreme Zigbee Smart Switch

Even judged purely on Zigbee among smart relays, the Shelly 2PM Gen4 has an edge over the Sonoff ZBMINIR2 Extreme Zigbee Smart Switch: it includes the radio directly with no bridge required, and stacks Wi-Fi, Bluetooth and Matter on top of it, while the Sonoff needs a separate Zigbee hub before it does anything and offers no other protocol. The Shelly 2PM Gen4 pulls further ahead with a complete set of overheating, overvoltage, overcurrent and overpower protections, two channels of built-in energy monitoring, cover mode with obstacle detection for shutters and blinds, a broader integrations list, and a 3-year warranty versus the Sonoff's one year. The Sonoff ZBMINIR2 Extreme Zigbee Smart Switch holds onto a lower price, settings that persist through a power cut via power-off memory, and confirmed wet-contact wiring that the Shelly 2PM Gen4 does not list. For anyone automating two circuits, a roller shutter, or wanting layered safety protection and energy data, the Shelly 2PM Gen4 is the clear pick; the Sonoff remains a cheaper, simpler option for a single Zigbee-only circuit.
