How Alternatives Compare to Sonoff
THIRDREALITY Zigbee Smart Plug 4-Pack
This ThirdReality option shifts your control from in-wall switches to standard outlets. It uses Zigbee connectivity, just like the Sonoff, but replaces a wall fixture with a plug. You gain the ability to control lamps and small appliances directly. The unit measures 2.6 inches long, making it bulkier than the Sonoff relay. It does not offer the 16A load capacity needed for high-power circuits like ceiling fans. Instead, it focuses on expanding your Zigbee network range while managing multiple devices. This choice suits users who prefer not to install hardware behind their wall plates or who need to automate portable electronics rather than fixed lighting circuits.
SONOFF Compact Zigbee Smart Switch
The SONOFF Compact Zigbee Switch offers a similar in-wall installation but targets two-way lighting circuits. It fits inside standard electrical boxes, just like the MINI ONE. However, it lacks the 16A load capacity, making it better suited for standard lighting loads rather than heavy appliances. It supports both Alexa and Google Home, providing broader voice assistant compatibility than the original device. The unit is slightly larger at 1.68 inches square. You need a Zigbee hub to operate it. This alternative is ideal if you are automating multi-switch setups in your home and require support for Google Home alongside Alexa.
Shelly 1 Mini Gen4 Smart Relay Switch
The Shelly 1 Mini Gen4 offers a different approach by supporting Matter and hub-free operation. It is significantly smaller at 0.63 inches long, fitting into very tight spaces behind switches. However, it does not support the 16A load capacity of the Sonoff, limiting it to smaller loads. It connects via Zigbee but adds flexibility for users who want to avoid relying on a specific hub. The device is blue and weighs only 0.71 ounces. You should choose this if you need a compact relay for low-power devices and value the ability to connect via Matter without additional infrastructure.
THIRDREALITY Zigbee No-Wiring Smart Switch
This ThirdReality device automates existing toggle or rocker switches without any wiring. It attaches to the faceplate of your current switch, preserving your home decor completely. It uses Zigbee and works with SmartThings and Home Assistant. The unit is 4.72 inches tall, making it much larger than the Sonoff relay. It does not handle the 16A load capacity and is designed for lower-power lighting circuits. This option is best for renters or users who want to avoid electrical work entirely. It provides smart control through a physical rocker interface while maintaining the look of your original switch.
Shelly 2PM Gen4 2-Channel Relay
The Shelly 2PM Gen4 manages two separate circuits instead of one. It fits behind your wall switch and connects via Zigbee. It lacks the 16A capacity of the Sonoff MINI ONE, so it is not suitable for high-power devices like large fans. The unit measures 1.65 inches wide and 1.46 inches high. It is black and weighs 0.92 ounces. This device is designed for users who need to monitor energy usage across two different lines. It offers hub-free operation and detailed power tracking. You should pick this if you need dual-circuit control and energy monitoring rather than simple on-off switching for a single heavy load.
Shelly 1PM Gen4 Relay Switch with Power Metering
The Shelly 1PM Gen4 provides precise energy monitoring for a single circuit. It connects via Zigbee and fits behind standard switches. It does not support the 16A load capacity of the Sonoff, limiting it to lighter electrical loads. The unit is red, 1.65 inches wide, and weighs 0.92 ounces. It offers hub-free operation and multi-protocol connectivity for flexible integration. This alternative is ideal if you need to track power consumption of your lighting or small appliances. You should choose this device if energy data is more important to you than the high load capacity provided by the original Sonoff MINI ONE.
