2026 verdict
It measures power, voltage and consumption, switches 16A across resistive, inductive and capacitive loads, lists overheating, overvoltage, overcurrent and overpower protection, and adds Zigbee through a hub with Zigbee routing. The
Sonoff MINI Dry Wi-Fi Smart Switch is the lower priced relay and brings a physical on/off button, overcurrent protection and a design built around the dry contact pulses gates and garage doors use, though it is rated 2A resistive. Both offer dry and wet contact modes, run on AC or DC, need a neutral when powered from AC and work with Alexa, Google Home, Apple Home, SmartThings, Home Assistant and Matter. Pick the
Shelly 1PM Gen4 to control and measure an appliance, and the
Sonoff MINI Dry Wi-Fi Smart Switch for a budget gate or garage trigger.
What owners say
Owners of both relays like how they fit into voice and home automation setups, and both mention instructions as the weak spot. Shelly 1PM Gen4 owners focus on metering, watching a water heater run, power-cycling a furnace or automating a dehumidifier, with praise for immediate Home Assistant integration and its Zigbee repeater role; they call the wiring diagram awful and find switching radios by button presses fiddly. Sonoff MINI Dry Wi-Fi Smart Switch owners focus on gates and garage doors triggered through the dry contact, with Alexa and Apple Home voice control and the manual button as a fallback, and their complaint is thin eWeLink guidance for pulse mode.
