I am migrating to HA as I am currently facing the problem that Hue can only sync 10 lights at once. So having a scene with 10+ lights is not working there without glitches. As my living, dining, and kitchen areas are interconnected sometimes I have around 30 lights in a single scene that should be fired by a press of a button.
The 10-light sync limit is quite well kept secret by Hue, so it was not easy to pinpoint the problems in my setup. But now that I am aware, I don’t want to have the same problem in HA.
So does anyone know / tested what is the limit of lights to synch in a scene?
I don’t know of a limit per-se on what HA can do… but that’s not your issue.
Determine where the limit comes from… If it’s a hue limit and ha controls hue then can HA overcome the limit? If you have a car that goes fast and you want to go faster you don’t control the same car with aremote you put in a faster engine…
If it’s only a hue issue maybe controlling the hue lights with zigbee works around it? But then you have to use zigbee not hue…
We don’t know until we know where that limit lies. So you really need to go find that out first.
Exactly what Petro said. Your limits are Zigbees limits. There’s nothing in here t in the spec that limits nodes.
I can imagine why Philips had those limits but they may not be relevant to your situation.
As an aside I rarely find need to have groups that exceed the number I have in a room and that is rarely over 6. I think the biggest I ever did at once had 8 unique groups but it was trying to do stuff all over true house at once. In my largest rooms I will end up banking lights and it’s two or three consecutive or successive calls.
Well, as long as they turn on and off I am fine. With the Hue some turned off some did not. Some remained on and I had to delete then repair the light to fix the issue.
I have around 80 lights all together for the whole apartment. Rail spots and recessed spots in the ceiling. 10W leds. As my living room, dining room and kitchen are interconnected, it can happen that 20+ lights are simultaneously operated in a scene. I set the mood for the whole space, not just for an area let’s say around the kitchen counter.
Whether under Hue’s hub, or another (Hubitat, HA) getting all my Hue bulb groups to act in unison was a desire I gave up on earlier this year. (6-10 in a group, among 80 bulbs installed)
I can’t speak to whether it relates to Hue in particular, or not. Here, nobody cares but me, anyways. [shrug] Still, I get the annoyance (I’m just choosing my battles more often as I age on).
Basically I have added only 3 lights into a scene, but already seeing performance problems with lagging, and sometimes lights remaining on or off, no matter if I turn lights on or off.
I have added them into HA as regular Zigbee, not through deCONZ. In deconz I was not even able to achieve a scene to work.
I am trying to eliminate scenes and just doing automations that manage the group of lights I want to use. This is a compromise as I can set only the brightness of the group, but it is an improvement over the scenes. It at least turns off and on most of the time all lights in an automation (not in synch though), but at least something.
Occasionally one or two lights remain on or off. Is it there a best practice that runs and checks if the lights all turned off and on and “repress” the turn off or turn on button again automatically? I see that as a somewhat solution for this. Basically doing a turn on or turn off trigger until all lights in a group turned on or off?
With the Hue some turned off some did not. Some remained on and I had to delete then repair the light to fix the issue.
