What is a smart dimmer?

A smart dimmer is an intelligent switch that allows you to remotely control the brightness of connected lights via an app, voice assistant, or a connected smart home system. Unlike traditional dimmers, a smart dimmer offers additional functionalities, such as automations, schedules, and integration with other smart devices. Smart dimmers often work with smart lights, but can also control traditional dimmable lights, such as halogen or dimmable LED lamps.
Benefits of a smart dimmer

A smart dimmer offers several advantages over a traditional dimmer:
- Remote control: With an app on your smartphone or tablet, you can dim the lighting or turn it on and off, even when you are not at home.
- Voice control: Smart dimmers can often be integrated with voice assistants such as Google Assistant & Amazon Alexa. This allows you to control the lighting with your voice.
- Automation: You can set schedules, for example to gradually dim the lighting in the evening or to dim and activate it at specific times of the day.
- Energy efficiency: By smartly dimming lighting and automatically switching it on or off, you can save energy and extend the lifespan of your bulbs.
- Customizable light scenes: You can create specific brightness levels or light scenes for different situations, such as "Movie Night" or "Working".
Types of smart dimmers
There are various types of smart dimmers, depending on the type of bulbs and the smart home system you use. Here are some popular variants:
- Standalone smart dimmers
These are smart dimmers that integrate directly into your existing switching system, without the strict necessity of smart bulbs. Some examples include:
- Philips Hue Dimmer Switch: This is a popular dimmer that works with Philips Hue bulbs, but can also control other Zigbee-compatible lights. It can be mounted directly on the wall and operated via the Philips Hue app.
- Lutron Caséta: This system offers a robust dimmer solution that works with various smart bulbs and voice assistants such as Alexa and Google Assistant.
- Built-in smart dimmers
You replace these dimmers just like a traditional switch in your existing wall box. They are connected directly to the electrical grid and can work with both smart and non-smart lights:
- Fibaro Dimmer 2: This built-in dimmer operates via Z-Wave and, in combination with a Z-Wave controller (such as SmartThings), can wirelessly dim and switch your lighting.
- Aqara Smart Dimmer: This Zigbee dimmer works with a Zigbee hub and can be integrated into systems such as Apple HomeKit and Google Home.
- System-dependent dimmers
These dimmers work specifically within a certain product line or smart home ecosystem, such as the dimmers for Philips Hue, IKEA TRÅDFRI, or SmartThings. They are designed to work seamlessly with the smart lighting and other devices within that ecosystem.
How does a smart dimmer work?

The operation of a smart dimmer depends on the specific model and system, but the basic principle is the same: the dimmer modulates the amount of current sent to the lamp, allowing the brightness of the light to vary. Via a wireless connection (Wi-Fi, Zigbee, or Z-Wave), you can control the dimmer using an app, voice assistant, or via automated routines.
Here are the key steps in how a smart dimmer works:
- Installation: The smart dimmer is installed in the switch box (for built-in models) or directly into an electrical outlet (for plug-in models). Some dimmers can be wall-mounted without wiring.
- Connection to your network: After installation, the dimmer is connected to your Wi-Fi network, Zigbee hub, or Z-Wave controller. This allows you to integrate the dimmer into your smart home system.
- Control via app or voice: Once the dimmer is connected, you can use an app such as Philips Hue, Google Home, or another specific app to dim the lights, turn them on or off, or set scenes. If the dimmer is integrated with a voice assistant, you can also control the lights using voice commands.
- Automation and routines: You can program the smart dimmer to turn on or off at specific times, or integrate it with other smart devices such as motion sensors. For example, the lighting can automatically dim as evening approaches, or turn on when you walk into a room.
How to choose the right smart dimmer?
When choosing a smart dimmer, there are a few factors you need to consider:
- Compatibility with bulbs: Not all dimmers work with all types of bulbs. If you have LED lights, make sure the dimmer is compatible with dimmable LED lighting. Some dimmers are specifically designed for use with halogen or incandescent bulbs.
- Smart home ecosystem: Choose a smart dimmer that works within your existing smart home ecosystem.If you already have Philips Hue, Zigbee, or Z-Wave devices, make sure the dimmer is compatible with these systems.
- Installation type: Determine whether you want a built-in dimmer that is installed directly into the switch box, or a plug-in version that is easier to install. Built-in dimmers often require more technical knowledge to install.
- Dimming functionality: Not all smart dimmers support every bulb; especially with LED bulbs, flickering light can occur if the dimmer is not properly configured. Therefore, choose a dimmer with good compatibility and options to adjust the brightness accurately.
