A small diamond bringing together the best experience and engineering

Smaller than two cookies stacked together, Shelly 2.5 can fit comfortably anywhere even if there are lots of cables. It’s 30% smaller than Shelly 1PM and only 5% bigger than Shelly 1, but can control two separate lighting circuits.

Follow the sun

Automatically follow the sunrise and sunset, and control your lighting accordingly. Shelly Dimmer 2 will gradually amplify lights in the morning and decrease them as night time gets closer. No more blinding lights during dark hours.

Overheating and overconsumption protection

Shelly 2.5 has an internal sensor for overheating protection. If the PCB temperature reaches dangerous levels, the device will turn off. It will also turn off the whole circuit immediately if it detects power consumption greater than the defined setting.
