I have 6 white Hue Bulbs. When I pair them to the Hue Bridge and a Hue Dimmer and turn them on they seem to go on all at the same time. But when I connect them to ST directly and write a simple Smart App to turn them all on there is a noticeable delay between the activation of the bulbs. I really can see how one after the other is turned on. The Device Handler I use is the “Zigbee Hue Bulb”. The command I use is simply “lights.on()” (were lights is the collection of all the lights - simple from the preferences of my app).
Has anybody else seen that and maybe know what to do to get all lights turned on at the same time?
