I´m still using SmartThings for all my light automations due to the simple fact that it does synced lights by default, and I would really like to see the same for HA. If we create a group of lights and then change the state of that group, they should be synced in my humble opinion.
I see there are a few workarounds that has been posted but it’s simple not feasible when you reach a certain number of lights and groups to maintain and keep track of.
With HA Yellow around the corner I was hoping to make the final switch and move all the lights over using ZHA in HA, but there are still a few things that bugs me, this is one and the other one is having a way to group automations, Wich has been pinned already and hopefully sees the light of day (pun intended) soon enough.
Ps, I tried making a general script that triggers on state change of Any group and auto generate a sync for its entities but failed to make it work, so if anyone by chance is in possession of anything like that I´m all ears.
