GE link bulbs stop responding

They all turn on after power is restored.

Check out this thread about a neat feature of these bulbs...

Hopefully Hubitat will add the configuration command to their built-in drivers. Pretty cool that the Sengled bulbs can announce their status when being powered off and on via a physical switch.

This would be useful if the power blips in the middle of the night as you could have a rule turn them all back off, assuming your hub is on UPS.
