WebCore lights require SetLevel on hub reboot

I have a System Start piston that used to work about 20 beta's ago, so 3 months?
Part of the start is to reset all ZB bulbs to off as sometimes they are on from a power restoral or a hub restart. We have many on beta. :slight_smile:

I have been chasing the failure of the lights to reset with delays and such but to no avail.
I was worried I might be overwhelming the ZB radio.
What I am finding is that after a reboot a lot of my ZB bulbs refuse to work from the Devices page or WebCore pistons; the System Start piston fails to turn the bulb on and off most of the time now. I have tried many drivers (Adv ZigBee, Sengled Classic and Legacy) no change.
I found that if I send the Devices a Set Level first then all the bulbs/groups respond right away.
Any ZB insight here? I have a gut feeling it's an HE change for the radio software; initialization for the ZB devices on reboot perhaps?
