Shelly Dimmer Gen3 WiFi Light Controller
Piegāde
LatvijaThe Shelly Dimmer Gen3 is a compact, single-circuit light dimmer that allows precise control of lighting brightness from a smartphone, tablet, computer or home automation system. It works over a Wi-Fi local network without the need for an additional hub, and also supports remote control via the cloud. It can work with or without a neutral wire. The device also offers Wi-Fi signal amplification, interoperability with Bluetooth and BLE Gateway, and a range of automation options, including schedules, scripts and integration with systems like Home Assistant, Google Home, Alexa or SmartThings.
The Shelly Dimmer Gen3 allows installation in both systems with and without a neutral wire, which is key when retrofitting existing installations. For operation without a neutral wire, a Bypass module is required if the load is less than 20 watts - such a solution prevents the lamp from accidentally glowing after it is turned off.
When the neutral wire is connected, the device allows the measurement of voltage (180-240 V), current (0-3 A) and energy consumption. These measurements are made with an accuracy of ±5%. In addition, the device is equipped with an internal temperature sensor and short-circuit and overload protection. Note: these functions work properly only when connected with a neutral conductor.
The product supports trailing edge mode, which provides smooth dimming of a wide range of light sources - from LEDs (up to 150 W) to halogen bulbs (up to 200 W) and electronic transformers. Automatic dimmer calibration guarantees a uniform dimming effect regardless of the type of light source. Built-in functions such as minimum and maximum brightness setting, transition time adjustment and night mode allow full control over lighting - both manually and through schedules.
Shelly Dimmer Gen3 supports up to 20 schedules and 20 webhooks (with 5 URLs for each). It allows you to create advanced scenarios using scripts and local actions. You can schedule brightness changes, transition times and set automatic light on/off. With support for MQTT, KVS and virtual components, deep integration with advanced building automation systems is possible.
