Shelly 1 Mini Gen3 vs Shelly Plus 1

The Shelly 1 Mini Gen3 wins overall on price and integrations, since it costs less and adds Matter support that the Shelly Plus 1 lacks. The Plus 1 is better rated by owners and handles heavier loads, up to 16A AC and 10A DC, so it wins when capacity matters more than size.

Load rating and size. The Shelly Plus 1 switches up to 16A AC and 10A DC, while the Shelly 1 Mini Gen3 is rated for 8A and 2000W AC and 5A DC. In exchange the Mini is significantly smaller, at 29 x 35 x 16 mm against 37 x 42 x 16 mm, which matters in a crowded back box.

Only the Shelly 1 Mini Gen3, which works with Matter alongside Alexa, Google Home, SmartThings and Home Assistant. The Shelly Plus 1 has no Matter or Apple HomeKit support, so it relies on Shelly's own integrations and local APIs to reach your platform.

Yes. Both the Shelly 1 Mini Gen3 and the Shelly Plus 1 require a neutral wire at the install point. If your switch box has no neutral, look at the Shelly 1 Gen3 or 1PM Gen4 instead, which are designed to run without one.

Buy the Shelly 1 Mini Gen3 if you need the smallest possible relay for a light, fireplace, sprinkler or garage door and the load is moderate. It supports dry and wet contacts, works with Matter, gives fast local control, doubles as a Bluetooth gateway and carries a 3-year warranty.

Buy the Shelly Plus 1 if the circuit needs the full 16A AC or 10A of low-voltage DC, or if you prefer the model with the longer track record and stronger owner reviews. It offers dry contact isolation, a UL-listed build, local operation with no cloud account and a 3-year warranty.
