Adaptive lighting support

[banaslee]

(For those out of the loop: adaptive lighting is a new HomeKit feature pretty much similar to what Circadian Lighting offers, or so it sounds)
As far as I understood, the new Adaptive Lighting feature in HomeKit on iOS 14 is something that needs to be supported in the bridge.
Hue has announced support for it later this year, IKEA hasn’t officially pronounced themselves about it. Doing it from HAP-python would bring support for all the supported lights at the moment.

If I understand the stack correctly this should be possible. Also, for anyone who can offer me some pointers, I’d like to look into the pieces of code that would enable something like this.

Btw, I haven’t found any documentation about Adaptive Lighting so I’m only working from assumptions on how it all works.

I'm happy to help, looks like it's already implemented in HAP-NodeJS: https://github.com/homebridge/HAP-NodeJS/blob/experimental/src/lib/controller/AdaptiveLightingController.ts

Great. So this should work on any light, even if the manufacturer does not offer it? How do I activate it?

How to get this work started?
I think the first step is to update the characteristics.json to include the new characteristics from iOS14.
Is that file generated or manually edited?

Looks like Homebridge 1.3 is coming with Apple Adaptive Lighting support (homebridge/homebridge#2765). Any update on this?

Hello @ikalchev
Can you please elaborate how to update the characteristics.json to include the new ones from iOS14? Is this a manual task?

Wondering if people are still interested in getting this implemented. The HAP-NodeJS Adaptive Lighting Controller is now located at https://github.com/homebridge/HAP-NodeJS/blob/master/src/lib/controller/AdaptiveLightingController.ts

This is slowly becoming standard in homebridge plugins. I'd rather not run my lights through homebridge to get AL support though

[egorgam]

Are any news about this feature?

[bdraco]

There isn't anyone working on this. It's not likely to happen any time soon.

[maurice-schleussinger]

Maybe we could set a bounty for an implementation?

[crazyfx1]

To implement this, I would need help by the maintainers for some basic questions. See my posts above.
Since I never got an answer, I couldn't proceed further, regardless of a bounty.

@ikalchev mind chiming in?

Jumping in as I'm migrating my Hue lights over to Zigbee2MQTT and hitting this limitation.

It looks like the last modifications to characteristics.json were done by @maximkulkin & @adrum for TV support. Any chance you guys could help point us in the right direction?

[bdraco]

There is nothing preventing manual edits to this file. Homebridge has already figured this out. I'm sure the community would be happy to share.

@crazyfx1, what's missing from characteristics.json? Found this doc -- https://developers.homebridge.io/HAP-NodeJS/classes/adaptivelightingcontroller.html

Seems to suggest that the characteristics needed are ColorTemperature, and Brightness. Optionally Hue and Saturation. All of these seem to already exist.
