2026 verdict
For metering, safety and radios, the Shelly 1PM Gen4 outclasses the Sonoff MINI Dry Wi-Fi Smart Switch in this Shelly vs Sonoff relay pairing.
It measures power, voltage and consumption, switches 16A across resistive, inductive and capacitive loads, lists overheating, overvoltage, overcurrent and overpower protection, adds Zigbee through a hub with Zigbee routing, and installs without a neutral. 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 and needs a neutral in AC input mode. Both offer dry and wet contact modes, run on AC or DC 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 the differences mean
Energy monitoring
The Shelly 1PM Gen4 reports power, voltage and total consumption on its circuit. The Sonoff MINI Dry Wi-Fi Smart Switch has no metering.
Load rating
The Shelly 1PM Gen4 switches 16A including inductive and capacitive loads. The Sonoff is rated 2A resistive, which is fine for a trigger signal but not for a water heater, pump or lighting circuit.
Neutral wire
The Shelly 1PM Gen4 is listed as installing without a neutral. The Sonoff needs one in AC input mode, or a 12-48V DC supply instead.
Radios and protection
The Shelly 1PM Gen4 adds Bluetooth and Zigbee to Wi-Fi and lists four electrical protections. The Sonoff is Wi-Fi only with overcurrent protection, but it has a physical on/off button the Shelly lacks.
Which one to buy if
- you want to meter and control a water heater or boiler
The Shelly 1PM Gen4 switches 16A and measures the circuit.
- you are triggering a gate or garage door opener on a budget
The Sonoff MINI Dry Wi-Fi Smart Switch is built for dry contact pulses and costs less.
- your box has no neutral
The Shelly 1PM Gen4 is listed as not needing one.
- you want a manual button on the relay
Only the Sonoff has a physical on/off button.

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.
