FAQ - Dynamic Lighting Settings
This option aims to make continual adjustments in your lighting setup by modulating brightness according to floating lux values or adapting colour temperature and brightness based on the sunâs changing elevation. Choose from six preset options available in the drop-down menu.
- Lux Controlled Brightness
- Lux Controlled Brightness - Inverted
- Sun Elevation Lighting - Colour Temp
- Sun Elevation Lighting - Brightness
- Sun Elevation Lighting - Colour Temp + Brightness
- Sun Elevation Lighting - Colour Temp + Lux Controlled Brightness
Please note:
- Dynamic lighting options are designed specifically for light entities within the light domain. Switches, scenes, and scripts are not compatible with the dynamic lighting options.
- When using dynamic lighting, your standard âLight Control Optionsâ are available according to your selections in the âLight Control Optionsâ input. For instance, choosing âUse Brightnessâ enables brightness control while keeping âColour Temperatureâ and âTransitionâ active if also selected. Keep in mind that âTransitionâ is always operational if selected, but âBrightnessâ or âColour Temperatureâ (or both) may be inactive depending on your dynamic lighting choices.
Below are two expandable sections depending on what information you are looking for.
Settings For Options 1, 2 & 6 - Lux Controlled Brightness Settings (Click Here to expand)
Option 1 & 6 âLux Controlled Brightnessâ
This will constantly adjust your lighting brightness % to a floating lux value. Example - When it gets darker your brightness will increase and as it gets lighter your brightness will decrease as shown in Figures 1-1 & 1-2
Option 2 âLux Controlled Brightness - Invertedâ
This will constantly adjust your lighting brightness % to a floating lux value. Example - When it gets darker your brightness will decrease and as it gets lighter your brightness will increase. It works the opposite way to option 1 & 6. On the graphs shown below, rather than going from high to low it will go from low to high as shown in Figure 1-3.
HOW IT WORKS
Figure 1-1
The below graph (Figure 1-1) shows the default settings. It shows as the lux value decreases, the brightness increases and vice versa.
With this setup when motion is detected and the lux value is equal or above 400 lux, then the lights will turn OFF (if they were ON) or when the automation gets triggered the lights will stay OFF because the brightness is set to 0%. If the lux value decreases then it will increase its brightness. The light will start to come on at around 399 lux. I say around 399 lux as some lights may need 1% to 10% brightness setting to turn ON. It all depends on your lights and your controller. At equal or below 40 lux, the lights will be set to 100% brightness.
The blue dotted line represents how to read the graph, at 200 lux it will be around 55% brightness.
- Max lux = 400 lux
- Min Lux = 40 lux
- Max Brightness = 100%
- Min Brightness = 0%
Figure 1-2
The below graph (Figure 1-2) shows a different setup. In this setup we have,
- Max lux = 500 lux
- Min Lux = 200 lux
- Max Brightness = 100%
- Min Brightness = 60%
With this setup when motion is detected and the lux value is equal or above 500 lux, then the lights will turn ON at 60% brightness. If the lux value decreases then it will increase its brightness. At equal or below 200 lux, the lights will be set to 100% brightness.
The blue dotted line represents how to read the graph, at 350 lux it will be around 80% brightness.
Figure 1-3
The below graph (Figure 1-3) shows a different setup. This is when you are using option 2 âLux Controlled Brightness - Invertedâ. In this setup we have,
- Max lux = 60 lux
- Min Lux = 20 lux
- Max Brightness = 100%
- Min Brightness = 20%
With this setup when motion is detected and the lux value is equal or above 60 lux, then the lights will turn ON at 100% brightness. If the lux value decreases then it will decrease its brightness. At equal or below 20 lux, the lights will be set to 20% brightness.
The blue dotted line represents how to read the graph, at 40 lux it will be around 60% brightness.
THE SETTINGS
The default settings are just random numbers I used. You will have to adjust them to suit your site conditions and to your liking. Play around with it and try different settings to make it work for you. Donât forget you still can also use the âtransitionâ and âcolour temperatureâ in âLight Control Optionsâ. Only âbrightnessâ in the âLight Control Optionsâ will be disabled if your use brightness in âDynamic Lightingâ. Transition is a nice way to smooth out your lights.

Dynamic Lighting - Ambient Light Sensor
This is the ambient light sensor that will be use. You can have a local light sensor in the same room as your lights or you can use and outside sensor.
-
Dynamic Lighting - Max Lux Value
You can see in the above graph (Point B) the maximum lux value is set to 400 lux.
-
Dynamic Lighting - Min Lux Value
You can see in the above graph (Point A) the minimum lux value is set to 40 lux.
-
Dynamic Lighting - Max Brightness Value
You can see in the above graph (Point A) the maximum brightness value is set to 100%.
-
Dynamic Lighting - Min Brightness Value
You can see in the above graph (Point B) the minimum brightness value is set to 0 % If setting the brightness to 0% then the light will turn OFF.
-
Dynamic Lighting - Heartbeat
This is the speed it will run at. At each heartbeat it will check your lux value and change the brightness if necessary. Every Lux sensor report differently so you will need to adjust this to suit your lux sensor. There is no point checking every minute if your lux sensor reports every two minutes.
-
Dynamic Lighting - Step Value
With every heartbeat, the system evaluates the lux value, light brightness, and the targeted brightness. If the targeted brightness surpasses the predefined step value, the system applies the set step value to gracefully moderate the rate of changes, facilitating a smoother transition in light brightness. You can also set the transition time in the âLight Control Options.â This further helps slow down the rate of changes per step to help smooth out the transition.
To understand its function, consider this scenario: imagine dynamic lighting aims to set your lights at 44%. With a Step Value set at 4%, if your actual light brightness is at 96%, instead of applying the full 44%, it adjusts to 92%. This adjustment pauses, allowing the LUX sensor time to adapt before proceeding to the next step, synchronized to your heartbeat setting. As your actual light brightness reaches 92%, the target value may be adjusted to 50%. This process repeats with each heartbeat until the target value aligns with your actual light brightness. The introduction of the Dead Zone comes into play when the target value approaches the brightness of your lights.
-
Dynamic Lighting - Dead Zone (±)
With every heartbeat, the system evaluates the current light brightness and the targeted brightness. If the targeted brightness falls within the defined dead zone, the system maintains the current light brightness. This prevents minor fluctuations in light intensity that could be bothersome to the eye.
To understand its function, consider this scenario: suppose dynamic lighting intends to set your lights at 88%. With a Dead Zone set value of 7%, if your actual light brightness falls between 81% and 95%, there will be no alteration to the brightness value. While a 7% Dead Zone might appear substantial initially, when testing it has demonstrated that it is actually considerably less than 7% of the intended value.
Trouble Shooting & Testing
In order for dynamic lighting to work well, it needs data from your lux sensor. Having a lux sensor that reports every 5 - 10 min + or on 5% change will not work well. The more data we can have the sensor provide the better it will work. Dynamic lighting only works with light (domain) entities. It will not work with switches and scenes.
A good way to test it is to add your motion sensor, light and lux sensor into a dashboard. This way you can see what is happening. Reduce your heartbeat to the minimum 0.25. If possible make your lux sensor report every 20 seconds. Now you will have a fast reacting dynamic lighting. From there you will then need to expand out your settings until you find what works for you. Below shows the dashboard.
Settings For Options 3, 4, 5 & 6 - Sun Elevation Settings (Click Here to expand)
Below, youâll find graphs illustrating the Sun Elevation feature within Dynamic Lighting. These visuals aim to provide a clearer grasp of the settings. As the saying goes, âa picture is worth a thousand words.â
By manipulating the proximity between the start and end points, youâre essentially altering the progression of colour temperature or brightness percentage along a linear path from their minimum to maximum values on sun rise or from their maximum to minimum on the suns descent until they reach the rising endpoint or descending endpoint. Changing the closeness or distance between these points adjusts the slope of the linear progression concerning sun elevation. In simpler terms, it influences how quickly or gradually the colour temperature or brightness changes as the sun rises or descends.
"The settings showcased in these graphs were as follows:
- Max Brightness Value = 100%
- Min Brightness Value = 30%
- Max Colour Temperature = 6500 K
- Min Colour Temperature = 2000 K
- Sun Elevation Rising - Start Point = - 1.5 degrees
- Sun Elevation Rising - End Point = 35 degrees
- Sun Elevation Descending - Start Point = 35 degrees
- Sun Elevation Descending - End Point = - 4.0 degrees
These settings were crafted as an example, demonstrating a transition from a warm, dimly lit ambiance to a brighter, cooler ambiance during the sunâs ascent. Conversely, during the descent, the settings showcase a shift from the brighter, cooler ambiance back to the initial warm, dimly lit ambiance. Itâs crucial to note that these values are provided as an illustration, encouraging users to customize settings according to their preferences and unique requirements
The lowest possible start point for the Sun Elevation rising phase and the lowest end point for the Sun Elevation descending phase is set at -10 degrees. Below these specified points, the settings utilize their minimum configured values.
