Set Shelly BLU Door/Window to turn on the lights as soon as you enter the room - no need to fumble for the switch. Once inside, Shelly BLU Motion takes over, ensuring that the room will be bright until you leave. If you have Shelly Dimmer2 connected to your lights, this dynamic duo also adjusts their brightness according to natural light levels. And as you exit the room, there's no need to worry about leaving lights on – they'll soon switch off, making your home not only smarter but also more energy-efficient.
