      Create the perfect home atmosphere that suits your mood.

      Why Shelly 2.5?

      The Shelly 2.5 was designed to have a maximum load of 2x2300W or 2x10A. Independent dual power metering for each channel allowing you to monitor the status and history, as well as the current and past electrical power consumption. 

      Shelly 2.5 Double Relay Switch and Roller Shutter

      Control any 110-230v Roller Shutter, motorised curtains or awning. With Shelly 2.5 you can open and close your garage door with a single tap, or even with your voice. Controlling roller shutters, garage doors, barriers pr any bi-directional motors have never been easier.

      Use with any appliance

      Shelly 2.5 controls a wide range of AC and DC power supply and you can control a wide range of devices.

      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.

      Full compatibility

      Shelly devices are compatible with Alexa, Google Home, Android, IOS and Samsung Smart Things.  With the voice assistants, you can command Shelly devices without having your smartphone around. 

      Warranty and Returns

      Typically, when purchasing Shelly devices directly from Europe or from other retailers, warranty claims are lengthy and expensive as the device must be shipped back to Europe. 

      When purchasing from the Smart Guys, if you have a fault with your Shelly Relay within 12 months of installation, give us a call and we will ship you out a new relay within 5 business days of assessment.
