How to connect


Roller shutter/blinds/tents/awnings/garage doors/barriers

Often you are in a rush when heading to work, and you want to get there as quickly as possible, or maybe you forgot to close the garage? With Shelly 2.5, you can avoid this, and when going out from home, open and close your garage door with a single tap, or even with your voice. Controlling roller shutters, garage doors, barriers, or any bi-directional motor has never been easier.

Control two independent circuits with 1 device

You are ready for bed, but start thinking if you have switched off the lights downstairs? Avoid this and control two independent circuits with one device. Simply install Shelly 2.5 at home and control the lighting of two separate lamps. They may be in the same or different rooms.
