GU10 spot blue at power on

remkog · May 15, 2023, 8:52am

Hi,

I have 2 Hue White and Color Ambiance Spot GU10

Since a few weeks they have weird behaviour. At power on (electricity) they give blue light in stead off white light.

I tried several things to solve the problem:

remove/add to Deconz
add to Hue Bridge to update the firmware
check the settings in Deconz VNC
install older version of Deconz

When I remove the spots from Deconz, they are working fine, meaning giving white light at power on
But when I add them to Deconz again, at power on I see a short delay before light is on and the light is… blue.

Is there a setting somewhere for power on behaviour?

Spot: Model LCT003
Firmware: 67.101.2

Deconz: 2.22.00 / 19-9-2022
Firmware Raspbee II: 26720700

Hi,

I think I have the same problem with my LCT015 version 1.101.2. When I add it to the deCONZ via Conbee II, it randomly turns blue when I turn on the bulb from the power switch. Have you managed to find any solution?

I can record video if more description is needed.

Hy guys,

I´ve tested the LCT003 (we don´t have the LCT015 here) with the Firmware 5.11.0.10732
No strange behavior, the bulb is safing the stats after you take it from the power. So, no problem here.
But I will test it with your firmware as well guys. You will here from us in the next days.

I have recorded video of the behavior: 20230612 164047 - Sendvid

I am using the power switch on the wall.

So it´s ok on the first click but blue on the second? Really weird.

deconzenjoyer · June 14, 2023, 9:25am

Yeah As soon as I disconnect it from my Home Assistant deCONZ addon, it starts working normally.

We cannot reproduce the issue with a LCT003 spot, the newest firmware 11.0.10732 of it and inside of Home Assistant. Do you switch of the light via power off or via a zigbee command (via app or zigbee switch)?

I have the same issue:

I’ve got a Pi4 with a ConBee II:

version: 2.22.02 / 19/09/2022
firmware: 26780700

Multiple LCT012 with firmware: 1.101.2.

They all show they same behavior as described earlier.

Is there any way I can help to debug this?

Thanks a lot!

I forgot, similar to the thread author - I use a real switch to power off/on the lights.

ich · July 24, 2023, 10:31am

Can you update the firmware of the light with a Hue bridge?

manamana · July 24, 2023, 3:45pm

@ich Thanks for your reply.

Probably I can do that.

Interestingly, this has been working correctly before and was only an issue with the last or second to last update of deconz - docker-based container.

Any ideas what could have caused this?

Can I downgrade to an older version of deconz to crosscheck?

manamana · July 26, 2023, 8:27pm

I had to replace one bulb.
Before adding it to deconz, the new bulb didn’t show the blue/white behaviour.

After adding it to deconz, it shows the blue/white behaviour.
Removing it from deconz, it doesn’t.

Any suggestions how to debug this?

I have the same issue. Yesterday I switched with two LTC007 from a HUE bridge setup to deconz. I bought both bulbs in one package (years ago), one is perfectly starting with the pre-power-off state, the second starts either with the described blue or with some white (but not the pre-power-off state). Are there any news regarding this behavior?

I also have this issue. After physical power up my lamps are blue. If I switch them off an on again, it’s normal light again.

Modell LCT003
Firmware 67.88.1

stale Bug report

### Does the issue really belong here? - [X] I definitively want to report a …bug within deCONZ or its REST-API ### Is there already an existing issue for this? - [X] I have searched the existing issues and there is none for the bug at hand ### Describe the bug Hi, I have two LCT007 Hue lights. I recently migrated them from the Hue Bridge to deconz , and now they’re exhibiting some strange behavior. Whenever the power is turned on (electricity), the bulbs default to blue light instead of white light. Here’s what I’ve tried so far to resolve the issue: Removed and re-added the lights to deCONZ. Added the lights back to the Hue Bridge to update their firmware. Checked all settings in deCONZ. Installed an older version of deCONZ. When I remove the bulbs from deCONZ, they work fine, displaying white light at power-on as expected. However, when I add them back to deCONZ, there’s a short delay before the bulbs turn on, and they emit blue light instead of white. Is there a specific setting in deCONZ to configure the power-on behavior of these bulbs? Details: Spot Model: LCT007 Firmware Version: 67.116.3 Stick: Conbee III Any insights would be greatly appreciated! ### Steps to reproduce the behavior When I remove the bulbs from deCONZ, they work fine, displaying white light at power-on as expected. However, when I add them back to deCONZ, there’s a short delay before the bulbs turn on, and they emit blue light instead of white. ### Expected behavior Not emitting blue ### Screenshots _No response_ ### Environment - Host system: - Running method: Raspbian - Firmware version: 26510900 - deCONZ version (not Home assistant Addon version!): 2.28.1 - Device: ConBee III - Do you use an USB extension cable: yes -- only relevant for ConBee I/II/III - Is there any other USB or serial devices connected to the host system? No ### deCONZ Logs _No response_ ### Additional context _No response_

This is not a bug in deCONZ; the power-on colour is a persisted setting in the light’s firmware. This setting can be accessed through the deCONZ GUI (Hue Startup Current X and Hue Startup Current Y in the Color Control cluster), and through the API (/lights/.../config/color/xy/startup). It’s probably set to [0, 0], causing the blue-ish colour. Personally I like set this to "previous", (or [65535, 65535] in the GUI) so the light powers up to its previous colour.
