Unable to find and pair Philips Hue lights (LCT001)

[madshell]

I'm very happy with my ConBee+Phoscon setup, I've meshed 35+ ZigBee devices together without much hassle so thank you for the great dev work.

My only problem is that I can't pair 3 Philips Hue E27 RGB bulbs. I don't have the dimmer switch so I have tested all the other methods that I've heard of:

• using the TouchLink feature of the old Phoscon interface at 10cm and even litteraly touching the Conbee II usb key -> I've never seen the lights showing
• using the Philips internal API of the bridge -> The lamp is doing its reset blinking but I can't find it in Phoscon app neither on the old TouchLink.
• deleting hub bulbs from the iOS v1 bridge app (official) while the lamp was turned on at 5cm or less -> the lamp doesn't seem to reset
• I even tried to switch Hue bridge on channel 15 to match the channel of my ConBee II stick -> no lights discovered

I'm litteraly stuck with no sign of life of Hue lights in the Deconz ecosystem whereas I can pair the bulbs very easily with the v1 bridge Hue app (iOS) even after a Hue bridge factory reset. What am I missing? Could this be a bug in latest firmware version with too old Hue bulbs?

My Pi setup:

• distrib: Raspbian GNU/Linux 9.9 (stretch)
• USB key: ConBee II usb stick
• version: 2.05.69
• firmware: 264A0700

The 3 hue bulbs:

• Philips Hue E27 RGB
• type: Extended color light
• modelid: LCT001
• swversion: 5.127.1.26581
• bridge: round (v1)

Connected devices:

• 24 various Ikea Tradfri bulbs
• 5 Ikea switches + 1 Philips Hue Tap
• 5 Xiaomi sensors + 1 Ikea motion detector

Solved by buying a dimmer switcher. Power on all lights, hold O/I buttons near each light until it stops blinking. Launch a light scan in the Phoscon web app and the 3 Hue bulbs were instantly discovered. So it's seems it's the only reliable method currently!

Had the same problem and tried @madshell workaround, but not get success with it.
But I remembered that I already bind this lamps to Hue-BT App, so what I did next:

• Select the Lamp
• Go to (...) -> Settings
• Press Reset

After those procedure each lamp discovered quickly by the deconz. Maybe this app was the cause the problem, maybe not, but this workaround worked for me.

I have the same problem with LCT001, SW: 5.130.1.30000.

1. I can connect the LCT001 to Hue Bridge v1.2 (7530) without any problems
2. Then I remove it from Hue Bridge (this should reset the bulb)
3. Search in Home Assistant Conbee II Home Integration. However the LCT001 is not found

Conbee is working fine as I was able to pair an Hue LLC020 and can control it without problems.
The Hue-BT App cannot be used anymore (says that you need to use the Hue App) and besides, I think the LCT001 does not have bluetooth.
