Having had some issues with my Hue Bridge and/or interface recently, I'm re-thinking the wisdom of having a large number of my devices connected to a separate hub so have just moved a few of them over to be connected direct to Hubitat. It went really smoothly if anyone wants to do the same - just delete them from the Hue Bridge in the Hue app and that leaves the bulb in pairing mode which Hubitat then found instantly as a Generic Zigbee Bulb and they work great. I have been careful not to move over any that are likely to be picked up as repeaters for other Zigbee devices as I know they can cause problems with that.
But the question is, when connected directly to Hubitat, can you chose the behaviour of the bulbs when they start up (eg after a power cut) as you could when they were connected to the Hue bridge? My bulbs have all had the firmware update to allow that feature in Hue and were set up to retain last settings there. But having just turned one off at the switch and back on again to test it, it came on even though it was previously off.
The bulbs I have moved are in bedrooms, so it would be a bit annoying to have them all come on if we had a power cut in the middle of the night which isn't unknown here. There is nothing in the Generic driver to set start up behaviour, and I couldn't see a specific Hue bulb driver other than the huebridge ones.
