Yes, I select more than one light for a toggle. I was testing with 2, but actually want to toggle 8 lights. I think the label "toggle these switches" is a bit misleading, as I would expect Hubitat to toggle them independently.
I'm struggling to figure out how to flash some lights twice, for notification, and have them end at the same state as before the notification.
I've ended up with 4 triggers, to toggle the lights after 0 seconds, 1 second, 2 seconds, and 3 seconds. And was expecting that at the end each light state would be as before the notification.
If I have to do it separately for each light, I'd need 32 triggers.
Note I ended up with 4 triggers, because I tried a trigger with a repeated action, and then another trigger which runs "stop actions", but that doesnt work consistently for some reason. Sometimes it failed to stop the action, even though in the log it says the trigger has run and it is stopping the action. And the continuous flashing lights didn't please the missus and kids too much!
