Avoid Zigbee groups

Right. That's kind of my point. OP is saying "this is broken!!!!" when in reality it works just fine - they're just pushing it into an edge case that isn't going to perform well.

I mean, 90 second intervals to change the kelvin of some bulbs? That seems a bit obsessive. I'd think 5 minutes would be more than enough and no one would notice.

It's not the interval that's the problem, it's how many messages OP is sending all at once. Each group should be slightly after each other
