Flows acting up containing groups

A while ago I migrated pretty much all my default automations in Home Assistant over to Node Red. Recently some of the automations I had setup seemed to not always run properly. This mainly involved any flows where I had used light groups as the entity.

So as a test I took a couple of flows and edited them using the actual light entities instead of light groups. Things have been much more stable so I did this with all my flows.

Just wondering why using light groups would cause flows not to run properly.

Stay safe and well.

I have observed the same for my lights that are further away from the Hue Bridge.
When using the light group, sometimes an individual light from the group did not turn on/off but the state in Homeassistant actually still showed it as on/off. Therefore, it seems to not be a NodeRed Problem.
Maybe you can check if the same is true for you?

Yes I had a similar experience,

In my basement office I have 3 ceiling lights and 2 lamps. Between sunrise & sunset if motion is detected all 5 lights turn on full at 6,500 Kelvin. Sometimes various lights would not turn on or off when no motion is detected. The state would show correctly in HA so if a light didn’t turn on from the Node Red flow it would show as being off in HA. I had the ceiling lights as one group and the lamps as a different group.

It is a pretty straight forward flow

Since I stopped using the group entities everything has worked perfectly, now in the node options I just select t multiple lights I want to turn on/off

I did not realize you could list multiple entities in one node. The other thing I found really useful is to use a simple timer to stagger some of the events especially in more complicated flows where lots of different lights are turning on or off. It just makes things far more reliable
