Circadian lighting with Home Assistant: Like f.lux, but for your house
I started a company to pursue circadian lighting (called Twist) and sadly pivoted away from it as a core value proposition because of weak reception from the market.<p>I feel we were 20 years too early (we shut down about 5 years ago).<p>Our tech enabled smart circadian lighting (we called it adaptive lighting) without configuration, an app, or wifi. The lightbulbs worked without any smart gadgetry necessary.<p>Every time the switch turned on the light made a 20 ms computation based on the time it stored (via a low power clock and a super cap) and turned to the right brightness and color temperature automatically. This was protected by a patent but also could not find a buyer for the tech despite how differentiated it was<p>Now I have an entire home with hue downlights + bulbs that does circadian lighting (with HASS as well) and while its not nearly as elegant of a solution as Twist (aforementioned startup), it is pretty great and a huge life changer to me and my fiancè.<p>Edit: for context we use Philips Hue downlight retrofits + bulbs in other fixtures, all white ambiance, and Lutron Aurora  dimmers, connected to HASS on a RBPI, running adaptive lighting from HACS
