Support for Hue Twilight

[boldiebold]

Please add support for the Hue Twilight.
Z2M can handle it, but Bifrost (Hue App) seems to struggle with it.

View in Z2M Group

Thanks

Interesting! Thank you for the bug report.

This is a rare occurrence of something that Z2m supports, but Bifrost has trouble with.

I'm going to need some more details:

1. When you say "seems to struggle with", what does that mean? How much is working? What happens? What goes wrong?

2. Please send me a complete Bifrost log file. If you're running from Home Assistant, there's a button to download the complete log.

Looking forward to hearing from you.

Here are a more details 1.) The twilight Light is appearing in the room/group. But nothing is working. With the hue bridge you are clicking on the twilight an it will open a front and back light which you can control independently. So z2m will handle it, too. A light device with two lights a front and back 2.) Here is the log [c9680598_bifrost-dev_2025-04-27T10-22-26.790Z.log](https://github.com/user-attachments/files/19929072/c9680598_bifrost-dev_2025-04-27T10-22-26.790Z.log) Thanks for take a look into it.

Thank you for the log.

I think I've found the problem!

...

The name contains a "/", which has special meaning in z2m topics.

This /front and /back, is that a name that z2m assigned, or did you name them like that?

I'm guessing z2m does this, right? Since it shows up as a single panel in your screenshot.

[boldiebold]

Yes you are right /front and /back are from z2m

[chrivers]

Alright, excellent. I think we found the root cause of the problems.

This is very unusual, and will require a few changes in Bifrost.

Are you available for helping test such changes in the dev branch?

[boldiebold]

Sure I will help

[chrivers]

I've read up on how z2m handles Hue Twilight, and it's difficult to figure out how to make support, when I don't have a Twilight myself. And they're a bit too expensive to buy on an impulse 😄

So the second best option - I need you to gather some data for me.

Specifically, a z2mdump, which is a condensed file containing all the details your z2m instance has on your devices.

To get it, you need to clone this repository, install the rust toolchain (goto https://rustup.rs and follow the instructions)

Then, run this command, from the bifrost directory you cloned:

cargo run --example=z2mdump -- "ws://10.0.0.100:8080/api?token=your-secret-token" > boldiebold-z2mdump.json

Replace the IP address and port number, with the ones from your config.yml, but keep the quotes, and the rest of the line.

If successful, you should now have a file called boldiebold-z2mdump.json, that contains the information I need.

It also contains pretty detailed information on all devices in your z2m instance, so you might want to send it directly to me, instead of attaching it here, that's up to you.

[boldiebold]

I will try ;-). Send it directly than to you

@chrivers Conceptually, the twilight consists of two named endpoints front and back (some fixes for devices with multiple endpoints were implemented in Koenkk/zigbee-herdsman-converters#8031). The introduction PR is here.
