FIBARO Walli Dimmer is a smart dimmer switch with integrated light switch. It works with commercially available lighting sources such as: LEDs, compact lamps, traditional bulbs and halogen lamps. The device is equipped with functions of automatic calibration and measurement of active power and energy. Select the color of the LED ring to suit your personal interior preferences. Use two backlight colors wherever you want - a different color at the bottom and another at the top to know the exact status of the device. Monitor the amount of energy consumed by your home equipment. Walli Smart Switches and Sockets are fully compatible with popular Google Assistant and Amazon Alexa voice assistants. Easy and comfortable voice management of the whole house. The FIBARO Home Center mobile app lets you manage smart switches and sockets with your smartphone, tablet or smartwatch.

I received the switch as a gift from the developer when I bought the apartment but decided not to go for the full smart home application.
