I am having problems with Room Lighting after I upgraded hub today. C-7 hub running version 2.3.6.136
When the Room Lighting task activates, it will set the levels on the bulbs, but the bulbs never turn on. And it reports "X" for device state, shown in the image below.
It was working yesterday, but stopped working after I did the Hub software update
See if you can control those bulbs directly from their device page... This happens when they don't report, so it could be that something is messed up with the bulbs.
I was updating I think at the same time as your response.
I can control the bulbs via the device list with no issues. But cannot seem to control through automations anymore.
I tried creating a Rule Machine task to turn on the bulbs but it does not work. I only used the Set Color Temp option, but that should have turned on the bulbs.
