Nanoleaf Matter thread lightstrip sluggish color translation

nchieffo commented 2 weeks ago

The problem

When I invoke the light.turn on on my Nanoleaf Lightstrip Matter, the light changes color in a super sluggish way, by performing non-smooth steps. This happens both if I use and don't use a transition in seconds. This does not happen when I use the Nanoleaf APP (but I guess it uses bluetooth to connect)

What version of Home Assistant Core has the issue?

core-2024.6.3

This is a device issue, not a HA issue. Please report the issue to Nanoleaf.

I don't think it's a device issue.

The reason why I say that is because if I control the light with my nanoleaf APP having Bluetooth disabled on my phone, color transitions are smooth.

It seems home assistant may use a different way to change the color than the Nanoleaf app.

Do you still believe I should open an issue with nanoleaf itself?

Thanks for your support

Home Assistant is the only controller actually implementing transitions and we figured out that some devices really have difficulties with that, while for others it works great. So far we found out that its troublesome on ESP32 based devices, running the 1.0 version of the SDK.

As this is not an ESP32 based device but Thread it should work fine, at least it works for the other Nanoleaf lights we have tested, such as the E27 and GU10 bulbs.

Can you provide a bit more detail on what is sluggish exactly ? Only a color to color transition or also a turn on/off ? What about brightness changes ?

I think I can take a video of the color transition which will clarify what happens: basically instead of changing from color A to B in a straight line in the color 'globe', it starts to move around with a curved line following a strange trajectory, causing weired color changes to the light. https://github.com/home-assistant/core/assets/632266/3a476a16-0b78-4976-8032-a316a5e8f1ce

See what happens when changing via nanoleaf app, HASSIO is able to track color change even if it's done via nanoleaf https://github.com/home-assistant/core/assets/632266/ab3b7584-cf00-4b22-b4d2-bae79f0abb32

Similar thing when changing TEMPERATURE. In the following video there's a comparison between nanoleaf APP and hassio https://github.com/home-assistant/core/assets/632266/f6c5be67-a7fd-418b-98a4-c4d1bab84e7e

Turn on from off is smooth only if the color is the same. If I'm in red, switch off, and turn on with blue, I still get the strange color route

Brightness change seems OK
