SONOFF vs Shelly Switch Specs
Connectivity protocols
SONOFF uses only Zigbee 3.0, which requires a dedicated hub to function. This keeps the device simple but dependent on extra hardware. Shelly 1 Mini Gen4 supports Wi-Fi, Zigbee, and Matter. You can connect it directly to your Wi-Fi without a hub. This multi-protocol approach offers more flexibility for different network setups. If you prefer a direct connection without additional equipment, Shelly provides that option. SONOFF is strictly for Zigbee networks.
Smart home compatibility
SONOFF lists compatibility with Amazon Alexa and Google Home. It relies on these platforms for voice control through a Zigbee hub. Shelly 1 Mini Gen4 highlights Matter support. Matter is a newer standard designed for broad interoperability between devices. While SONOFF works with major voice assistants, Shelly’s Matter certification suggests easier integration with various ecosystems. Both allow remote control via their respective apps. Shelly offers a more future-proof path with Matter.
Wiring requirement
SONOFF ZBMINIR2 requires a neutral line for installation. This is a standard requirement for many smart switches but can be difficult in older homes without neutral wires in the box. The data notes it works with external switches for no-neutral scenarios, but the core unit needs neutral. Shelly 1 Mini Gen4 supports dry contacts and can be installed in tight spaces or inside appliances. It does not explicitly list a neutral requirement in the same way, offering more flexibility for retrofitting into existing wiring without neutral.
Physical dimensions
SONOFF measures 1.68 inches in width and length, with a height of 0.79 inches. It is described as super tiny for EU or 86-type boxes. Shelly 1 Mini Gen4 is 1.34 inches wide, 1.14 inches high, and 0.63 inches long. Shelly is slightly narrower but taller. SONOFF is flatter. Both are designed for small spaces. SONOFF fits standard 86-type boxes easily. Shelly’s compact form factor allows it to hide inside appliances or garage door openers. Both are small, but SONOFF is flatter.
Power capacity
SONOFF does not list a specific amperage rating in the provided data. It mentions working with lights as low as 3W. Shelly 1 Mini Gen4 supports a maximum load of 8A. This capacity allows it to handle small to medium-sized appliances like coffee makers or lamps. The 8A rating provides a clear limit for what you can connect. SONOFF’s lack of a stated amperage makes it harder to compare directly for heavy loads. Shelly gives you a defined power ceiling.
Choose the right switch for your setup
You want direct Wi-Fi and Matter control
The Shelly 1 Mini Gen4 connects via Wi-Fi and Matter, so you do not need a separate hub. This direct connection simplifies your smart home network. Its compact size fits tight spaces, and the 8A load capacity handles various appliances. You get reliable control without extra hardware dependencies.
You prefer dedicated Zigbee hardware with a hub
The SONOFF ZBMINIR2 relies on Zigbee 3.0, which requires a hub but creates a stable local network. It supports two-way control and works with Alexa and Google Home. This model is ideal if you already have a Zigbee hub and want a dedicated device for your lighting automation needs.
You need flexible installation in tight spaces
Shelly offers a very small form factor with dimensions of 1.34 by 0.63 inches. This allows it to fit inside appliance casings or small switch boxes. The 8A capacity lets you control lamps and garage doors easily. Its multi-protocol support ensures it works with your existing smart home ecosystem.
