The Shelly Dimmer Gen4 smart dimming module allows you to turn existing lighting into smart lighting without having to change switches. Once installed behind your wall switch, you can conveniently adjust the brightness of your lighting, set minimum and maximum brightness levels, as well as the dimming speed and transition time, making it easy to adapt the light for work, relaxation, or the evening atmosphere. The Shelly Dimmer Gen4 supports dimmable LED sources up to 150W, conventional and halogen bulbs up to 200W, and selected transformers, with a maximum output power of 200W. Thanks to Wi-Fi, Bluetooth, Zigbee, and Matter support, you can easily integrate it into various smart home systems, and via Matter, it can be used with Apple Home, Google Home, Amazon Alexa, Samsung SmartThings, or Home Assistant, for example. Using the Shelly Smart Control app, you can create schedules, smart scenes, and automations, such as adjusting the brightness to the time of day or synchronising the lighting with sunrise and sunset. When combined with a Shelly BLU Motion sensor, the Shelly Dimmer Gen4 can automatically turn on the light when motion is detected, while the night mode allows you to use a preset, dimmer brightness during selected hours. The compact design, measuring 38.5 × 43.5 × 17mm, facilitates installation in tight spaces behind the switch and preserves classic physical light control. When connected without a neutral wire and with a load of less than 20W, it is necessary to use the Shelly Bypass for the dimmer.
With the Shelly Dimmer Gen4, you can easily set the light intensity to perfectly suit the current situation—from full brightness for work and concentration to a pleasantly dim light for evening relaxation. In addition to the minimum and maximum brightness levels, you can also adjust the dimming speed and transition time, ensuring smooth changes in lighting. This allows you to create the right lighting atmosphere for work, rest, and everyday activities.
Thanks to the Shelly Gen4, you can upgrade your existing lighting and gain smart features without having to change your wall switches. The compact module is installed directly behind the existing switch and can be connected both with and without a neutral wire, making it suitable for older electrical installations as well. This way, you preserve the original look of your interior while gaining smart dimming, schedules, scenes, and automations.
With the Shelly Dimmer Gen4, you can set your lighting to automatically adapt to the course of your day. Using schedules, you can, for example, set a higher light intensity in the morning and gradually reduce the brightness as evening approaches for a more pleasant atmosphere. You can also synchronise the lighting with sunrise and sunset, so the settings change automatically according to the current time of day.
With the Shelly Gen4, you can easily create a pleasant lighting atmosphere in restaurants, bars, hotels, or lounges and adapt it to different parts of the day. During the day, you can use brighter lighting, while in the evening, you can smoothly dim the lights to create a cosier and more relaxing environment for guests. Thanks to adjustable scenes and schedules, changes in lighting can also be automated.
You can easily integrate the Shelly Dimmer Gen4 into your smart home and connect it with platforms like Home Assistant, Google Home, Amazon Alexa, or Samsung SmartThings. This allows you to control your lights from a single environment, include them in scenes and automations, or link their behaviour with other smart devices in your home. You can then adjust the lighting as part of your created routines or conveniently change its intensity using a compatible voice assistant.
Thanks to the Shelly Dimmer Gen4, you can assign multiple functions to your existing physical button and control the lighting conveniently without opening the app. The module can recognise single, double, and long presses, and you can assign different brightness levels or the activation of selected scenes to each action. For example, a short press can turn on the light, and a long press can adjust its intensity.
When paired with a Shelly BLU Motion sensor, the Shelly Dimmer Gen4 can automatically turn on the light the moment it detects movement. This is particularly useful in hallways, on staircases, or at entrances, where it ensures the space is lit exactly when you need it. This means you don't have to search for a switch in the dark, and you can also set the appropriate light intensity for that space.
The Shelly dimmer is part of the new Shelly Gen4 generation of devices, which offers more flexible options for connecting and automating your smart home. Thanks to support for Wi-Fi, Bluetooth, Zigbee, and the Matter standard, you can choose the communication method according to your system and more easily integrate the sensor into your existing ecosystem. Multiple communication protocols also expand the possibilities for creating automations and linking with other compatible devices. This allows you to use the light dimmer as a universal smart home component without being limited to a single connection methour
