Hello everyone!
I use the Aqara W100 all year round. During the winter months, it helps me to monitor the indoor and outdoor temperature and manage my heating more efficiently. In summer, however, I don’t need it for temperature control as my thermostats are turned off, so the W100 takes on a different role entirely.
It becomes my central controller for all the lighting in my living space. I’ve set up dedicated modes for different occasions: a cosy Cinema Mode for watching movies and a colourful Party Mode for more vibrant moments.
In the video below, I demonstrate how each of these modes works and how the W100 triggers the different scenes and automations.
Sequences in the video
1. Controlling the lights:
- Short press on the middle button: the LED strip turns on
- Long press on the middle button: the small lamp turns on
- Short press on the plus button: the light becomes brighter
- Short press on the minus button: the light becomes dimmer
2. Cinema mode triggered by long-pressing the plus button on the W100:
- The electric roller shutter lowers
- Apple TV turns on
- The LED strip turns on with dimmed light
- The small lamp turns on with dimmed light
3. Cinema mode reactions when Play/Pause/Stop is pressed on Apple TV:
- When the video is paused, the LED strip and the small lamp become brighter
- When playback continues, the LED strip and the small lamp dim again
- When the video ends, the LED strip and the small lamp brighten up
- When the Apple TV shuts down, the LED strip and the small lamp increase brightness all the way to 100%
4. Party mode triggered by long-pressing the minus button on the W100:
- The LED strip flashes in different colors
- The small lamp flashes in different colors
- A fireworks video plays on the Apple TV
Here is the setup, with all scripts and automations in Home Assistant.
1. Controlling lights
Below is a brief overview of the automations in Home Assistant.
You will find the full setup below, complete with images and YAML.
It is, of course, imperative that you adapt entity and device IDs.
1.1. Increase brightness
Whenever I press the W100 plus button (single or double press), this automation increases the brightness of my LED strip and small lamp. If both are off, the LED strip brightens first. If one or both lights are on, each light increases its brightness independently, giving smooth and responsive control.

1.2. Decrease brightness
Whenever I press the W100 minus button (single or double press), this automation decreases the brightness of my LED strip and small lamp.
Only lights that are currently on will dim, so each active light decreases its brightness independently.

1.4. LED strip on/off
Whenever I press the middle button on the W100 (single press), this automation toggles my LED strip on or off. If the LED strip turns on, the small lamp is automatically turned off. This lets me easily switch the main lighting on while keeping the small lamp off.

1.5. LED bulb on/off
Whenever I press the middle button on the W100 (long or double press), this automation toggles my LED bulb on or off. If the lamp is off, it turns on with a warm light at 2800 K and 30% brightness. If the lamp is already on, pressing the button turns it off.

2. Cinema mode
When I long-press the plus button on the W100, this automation activates my Cinema Mode. If the Apple TV is off, the electric roller shutter lowers to 80%, the Apple TV turns on, and both the LED strip and small lamp turn on with a warm, dimmed light (2700 K, 10% brightness) over a smooth 3-second transition. If the Apple TV is already on, pressing the button again will turn it off and gradually switch off the lights after a short delay. This creates a cozy, cinema-like atmosphere with minimal effort.

3. Syncing with Apple TV
Below is a brief overview of the automations in Home Assistant.
You will find the full setup below, complete with images and YAML.
3.1. Light when pause TV
Whenever I pause a video on the Apple TV, this automation adjusts the lights to create a more comfortable viewing experience. If the LED strip is already on at a moderate brightness, it temporarily brightens the strip to 80% and the small lamp to 30% with smooth transitions, creating a subtle ambient light for the paused scene. If the lights were off or dim, the strip turns on to 65% and the small lamp to 10%, so the room isn’t completely dark while watching or pausing late at night. This way, the lighting responds naturally to pausing the TV, enhancing comfort without being too bright.

3.2. Light when play TV
Whenever I resume playback on the Apple TV, this automation restores the lights to their previous state. If the LED strip was very bright before pausing, both the strip and the small lamp are turned off. If a snapshot of the previous lighting exists, the lights gradually return to that saved state over a smooth 3-second transition. This ensures that when the video continues, the lighting seamlessly adapts, maintaining the perfect cinema-like atmosphere.

3.3. Light when switching off TV
Whenever I turn off the Apple TV, this automation gradually brightens the lights to a comfortable level. The LED strip ramps up to 100% and the small lamp to 50% over smooth 5-second transitions, creating a gentle, well-lit environment after watching. This ensures the room is comfortably illuminated, perfect for putting away snacks or finding lost popcorn.

4. Party mode
When I long-press the minus button on the W100, this automation toggles Party Mode on or off.
When Party Mode is activated:
- The Apple TV turns on, selects YouTube, and starts playing a fireworks video.
- Both the LED strip and small lamp flash in random colors repeatedly, creating a dynamic party atmosphere.
When Party Mode is deactivated:
- The Party Mode script stops, the Apple TV turns off, and after a short delay, both lights are switched off.
This setup enables me to start or stop fun, colourful lighting effects instantly. It’s perfect for entertaining or celebrating!
