Dimmer 2 is a compact dimmer relay designed to fit in most switch and socket back boxes. The Dimmer 2, which connects to a wireless network, makes it easy to turn traditional lighting into smart lighting. After installation, the lights can still be used traditionally via the wall switch.

Dimmer 2 can be set to follow sunrise and sunset so the lighting adjusts automatically. The dimmer gradually increases light in the morning and reduces it as evening falls. The lighting can also be easily adjusted for optimal conditions, e.g. for reading or watching TV.

Safety features include an internal temperature sensor. If the circuit board temperature rises too high, the device shuts off immediately. A separate power threshold can also be configured. If Dimmer 2 detects consumption above the configured setting, the device cuts power immediately.

Shelly smart home products support the Amazon Alexa and Google Assistant virtual assistants. In addition to the above, several other smart home systems/platforms are supported (verify compatibility per product). Shelly products connect to a wireless Wi-Fi network and do not require a separate home automation controller to operate.

Note! You will need an electrician's help for fixed electrical installations. If a single Dimmer 2 relay is used to control several different lights, the controlled light sources must be identical in terms of power and operating technology. When used without a neutral wire, Dimmer 2 requires a minimum current consumption of 10 W to operate. If the connected light’s power consumption is lower than this, a separate Shelly Bypass device must be installed in between.
