I have a Hub v2, running firmware 20.17 in the UK.
I have 3 Hue bulbs (2 color, 1 white) which have worked great for several months, but they have been offline now for around 4 days, which I think is the time when my hub updated to firmware 20.17.
Bulb 1 and 2: Philips LCT010
Bulb 3: Philips LWB004
I have tried rebooting my Smartthings hub, leaving it unplugged for 15+ minutes, and Edit->Update on the device, but none of these have succeeded in restoring functionality. I don’t have the Hue bridge or a Lutron remote to be able to reset the bulbs.
Can anyone help?
