Shelly Smart Dimming Controller Gen4

The Shelly Dimmer Gen4 is the direct successor of the Shelly Dimmer Gen3, and retains many of the features that made its predecessor so popular; like the Dimmer Gen3, the Dimmer Gen4 doesn't require a neutral wire (although a bypass is required when the load is under 20W), and can be retrofitted into existing lights by using pre-existing wiring. The Dimmer Gen4 supports a wide range of lights - halogen and incandescent bulbs, dimmable LEDs and transformers, and more - and can act as a standalone flicker-free dimming controller, or be integrated into a wider Shelly Smart scene involving many Shelly devices such as motion detectors.

The Dimmer Gen4 features significantly improved connectivity options over its predecessor - natively supporting Bluetooth, WiFi, Matter and Zigbee with easy adoption - and an upgraded chipset for better responsiveness and processing power. It's also capable of measuring the power draw of any connected lights or lighting systems, reporting on energy usage every 60 seconds to an accuracy of within 1%; these measurements are then securely stored in the cloud for later analysis.
