DIMMER GEN3

DIMMER GEN3

Shelly Dimmer Gen3, is a single-channel smart dimmer controller that stands out with its support for use without a neutral wire. It allows you to remotely control dimmable lamps and drivers via a mobile app, tablet, computer, or automation systems. It can operate independently with a local Wi-Fi network or be used in integration with cloud-based services.

It supports many features such as advanced timers, automation scenarios, transition times, and minimum/maximum brightness settings. Power measurement is activated only in neutral-connected use. The device supports single/dual dim control modes with physical switches and detects the best dimming range thanks to its automatic calibration feature.

Equipped with advanced technologies such as Bluetooth connectivity, BLE Gateway, Wi-Fi extender, automation with ShellyScript, and KNXnet/IP compatibility, the Shelly Dimmer Gen3 can be easily mounted in tight spaces due to its compact design and does not require a central HUB.
