Circadian Mode for Philips Hue

Restful is a company focused on making lighting healthier. We have had success with our Bedtime Bulb product, with over 40,000 customers.

We believe that circadian lighting, or light that shifts throughout the day to maximize daytime bright light and minimize nighttime blue light, should be a standard feature in all lighting in the future.

We are not affiliated with Philips, Signify, or Hue. We simply want to make lighting healthier, and we have been disappointed in the circadian options introduced into the Hue app over the years.

The Atmos Bedside Lamp is a fully automated circadian lamp. Circadian Mode replicates Atmos' automated shift throughout the day and night. However, the quality of light is lower on Hue bulbs and lamps: lower color rendering index, higher blue spike, and more flicker compared to Atmos.

Bedtime Bulb v2 is a purpose-built bulb for the nighttime. While Bedtime Bulb v2 does not automatically shift throughout the day and night, it offers much higher quality of light than Hue during the nighttime mode, including less flicker, higher color rendering index, and infrared.

Compared to both products, Circadian Mode will require the Hue bulbs to be brighter at night for the same visual fidelity, which means more unwanted circadian input. Circadian Mode will also need the Hue bulbs to be brighter than the Atmos lamp during the day for the same circadian input, which is more uncomfortable.

Right now, we are offering Circadian Mode in public beta, and the first few users will be entitled to a free year of service. In exchange, we want to hear your feedback about how we can make this product great.

We do plan to eventually shift to a monthly subscription, likely in the range of $5-$10 USD per month, depending on the number of lights connected.

The Natural light scene only allows a small number of sub-scenes, with limited customization. It can only adapt to the sunset time, and not the sunrise time. The transitions are harsher.

Circadian Mode gives you much more control over the color temperature and dimming shift throughout the day. We are also working on additional innovations, such as a machine learning feature that learns your brightness preferences and automatically applies them, without requiring manual adjustments to the schedule.

We are also listening very closely to user feedback and rapidly implementing features, so you can have the most control over your circadian scene.

Home Assistant is a great solution for users who want lots of control over their smart homes. However, it requires significant effort to set up and maintain.

Circadian Mode is designed to be much simpler. All you need is a Hue system connected to the internet. Circadian Mode is a web service, so you don't need to set up additional hardware.

Additionally, Circadian Mode limits its scope to the scene it creates, so if won't override your settings if you are in another scene. We believe this is a more reliable and less frustrating approach.

HomeKit Adaptive Lighting is a simple solution for Apple Users. It requires an Apple Device, such as an iPad or Apple TV, to be present in the home at all times. It offers little-to-no customization over the circadian schedule.

Yes! There is an option to adapt to local sunrise and sunset times based on your precise location. Alternatively, you can apply a fixed schedule that does not shift day-to-day.

Right now, the schedule bottoms out at 2000 Kelvin and a low brightness at night. However, it would be trivial for us to add red and amber nighttime modes: please just let us know if you'd like this!

No! Circadian Mode is a standalone software product. All you need is a Hue system connected to the internet.

At the moment, Circadian Mode is a web app that works on your computer, tablet, or phone in the browser. You can create a shortcut on your mobile app.

We are listening closely to customer requests, and if there is enough demand, we will definitely consider a mobile app.
