It is nice that the ST app lets you add lights to a group, but it seems you can’t make a group of lights an automation target - e.g. “turn off the indoor lights group at 1am”. Instead you seem to have to manually add all the lights to the rule.
This is my second most wanted feature. I have two sengled bulbs linked to a smartthings multipurpose sensor. When I open a door, the two lights will turn on one at a time. I want to automate the lights as a group so that they turn on simultaneously. Is there a way to achieve this?
