Circadian Lighting

Circadian Lighting is a new driver suite by Janus Technology that allows you to easily program a circadian rhythm for any tuneable white dimmers in your project.

Each circadian lighting controller can configure a schedule entirely from composer for a subset of lights you choose from your project - this means you can have multiple entirely different schedules running in one project, with a different subset of lights being controller by each!

Common use cases of this would be to synchronise the colour temperature of your lamps to your location's daylight, or possibly even your sleep schedule to give warmer colours at bedtime and cooler ones during the day.


Webview Compatibility

The Circadian Webview driver that also comes in this suite provides a very intuitive way to configure all circadian lighting controller drivers in your project, by using Control4's WebView technology! You can access this enhanced interface through Control4's T3 table-top and in-wall touch-screens, making it quick and intuitive for your client to modify their circadian schedules whenever they choose.

If you don't have any T3 screens in your project, don't worry - this interface can still be accessed through any web browser, by entering the following address into your browser, substituting in the IP address of your Control4 processor.



Whats New?

How does the ‘Smart Light Level Monitoring’ work?

Smart Light-Level Monitoring allows you to adjust the brightness or warmth levels of a controlled light without interrupting the circadian rhythm.

Say you have a bulb included within a circadian schedule, and you want to manually change the brightness of that bulb as a one-off change. Circadian will notice that this bulb has had its brightness changed externally, and so will not set its brightness with any future commands, while keeping the warmth in line with the circadian rhythm.

A bulb will be automatically re-aligned with the circadian rhythm when it is switched on from 0.

Can I place Circadian Webview in the lights experience menu?

Unfortunately, the Control4 UI prohibits devices that are not specifically light drivers from appearing within the lights experience menu.

Circadian Webview can, be shown alongside Comfort, Listen, Security and Watch. This can be customised from the room navigator interface in composer.

For systems running OS3, you can also favourite Circadian Webview to the room by pressing and holding on the UI icon from a T3 touch panel.

Will you be supporting more tunable white drivers in the future?

If you want to use a driver with Circadian Lighting that isn’t currently supported, please contact us quoting the driver name and download link and we will be happy to add support quickly!
