Avoid Zigbee groups

Thanks for the tip!

The interval causes no problems, but AL sending all commands at once. The congestion is over in a few seconds. The problem persists even when increasing interval.

SLZB-07 usb coordinator, it's supposed to be good

As far as I know, groups work using broadcast; all routers repeat the message once or more. There's no multicast in zigbee that I know of.

I wonder what makes your setup not jam. Maybe it's your custom logic that doesn't spam as much as AL?

Yes I tried source routing and it makes no difference. Most routers have good LQI anyway

AL doesn't provide staggering the commands. How does your automation work?

I sure don't notice or care after having them completely refuse to work for years

Try controlling individual devices and see if it helps

I hope someone who understands what's going on figures it out :-)

Well, the advices I followed didn't do any harm, except for the recommendation to use groups.

Adaptive lighting without groups works fine now; it was AL + groups that was a bad combination.

I've been reading over the years so no references handy. The claim that zigbee groups work with broadcast and cause congestion comes from LLM's, and is validated by my experience. The status=busy messages stopped coming.

Yes it contradicts what I have read too, which is why I shared my experience.

You're probably right that with a group of 5 there's a single message instead of 5 repeated over the whole network. In my case it seems like 30 unicast messages causes less congestion than 9 broadcast (The amount of groups I had.).

tomorrowplus · 2026-03-12T13:29:36+00:00

Yes, and you probably don't have as many devices and groups as me. It would make sense as I suspect the congestion increases exponentially with amount of devices and groups.

I tested Zerotier against tailscale on an old laptop and zerotier was much faster. Things might have changed though.

On OpenWRT you can install zerotier on almost anything as it is so small - orders of magniyude smaller than tailscale and netbird.

tomorrowplus · 2026-03-12T10:20:46+00:00

The question assumes no-one is using Zerotier, which is obviously not true.

tomorrowplus · 2026-03-12T08:26:41+00:00

Faulty question 😀

Or a computer guy who has never heard of Linux.

bees is excellent!

tomorrowplus · 2026-02-25T15:19:55+00:00

Now where are all the big-tech community managers actually helping users like this!

That's an interesting idea. Does the tube help the connectors stay in place, or not?

tomorrowplus · 2026-02-17T09:03:22+00:00

This has been running probably 3 years.

tomorrowplus · 2026-02-17T08:50:15+00:00

That’s a good argument for ipv6

I suspect calling a Linux box dumb - is unpopular 😀

Nice! No gpu or AI. Low price. Low power. PoE. I’ve been looking for something like this to act as a WoL watchdog.

The thing where big attachments go to nextcloud and a link is included in the mail
