Hi, just to let you know.
I have changed my setup from RaspBeeII to ConBeeIII at the beginning of this year. After that, the 1st Gen Hue lights worked again with the latest firmware.
LCT001 - Bulb, FW: 67.101.2
LLC010 - Iris, FW: 67.93.11
LLC011 - Bloom, FW: 67.93.11
LST001 - Lightstrip, FW: 67.93.11
For me, the problem is solved.
(deCONZ: 2.24.3, ConBee III FW: 264F0900)
