Zigbee Network Issues

Just to have a look I tried this and got a printout.
If you wouldn't mind, how do I interpret this for devices being repeated. TBH I don't think I have any but just wanted to know how things would show up if I did.

You don't have repeaters for all those Xiaomis?

16

It looks like you only have battery devices. I don't have many ZigBee devices but this is what I get. The Neighbor Table shows powered ZigBee devices. The route table shows how devices are routed to the hub. I would like to understand more. The alphabet soup and numbers do give clues to how things are doing but I haven't dug into that.

None. My hub is pretty central though.
I do get the odd drop off occasionally so perhaps I should invest in a couple.
Just for information if I get a zigbee outlet, when it is plugged in but turned off, I assume it keeps repeating as it is powered.

18

Correct!

Since you have plenty of Xiaomi devices, you may want to get zigbee routers (repeater) that is compatible with Xiaomi. Take a look at this thread for information what is work as Xiaomi repeaters.

20

Thanks for the information. Will have a look.

@bobbles

FWIW, the Ikea Tradfri plugs work as repeaters for Xiaomi sensors and are relatively inexpensive at $9.99 ea.

That's a couple bucks cheaper than the Tradfri Signal Repeater.

I'm not sure where you are getting that image (you don't cite your source), but it's not showing the whole picture. This site provides a better explanation than that image. With zigbee on 15, only wifi channel 11, and maybe 10 or 9, will avoid any interference with each other.

23

My image is based on 22MHz channel, I got it from Smartthings forum.

And this other image is from Apple not recommending 40MHz channels

Here another page, similar image with 22MHz channels

Either way channel 11 which is what I use is far enough away that there should be no interference with Zigbee channel 15.

Really?!?! What does this mean. I am quite sure I have > 32 zigbee devices.

26

On some hubs (ST for example) only 32 end nodes can be connected directly to the hub. To support more you would need some router devices.

Some hubs support more (Hue hub) some don't. Depends on design and what Zigbee class they support.

27

32 non routing zigbee devices. Routing devices do not count towards this limit.

With enough routing devices, basically anything powered by AC and not battery, there is virtually no limit to number of zigbee devices in a mesh.

28

Certainly no PRACTICAL limit...

Some say 64000, some say more... Some say when you get to the low thousands it becomes inherently unstable... Regardless - more than a home HA system needs.

I support some very large 802.15.4 networks in the industrial space - many hundreds of end nodes with no issues.

29

Just looking at my zigbee logs to see the strength of the signal from the various devices.
I assume the Rssi figure is the crutial value.
What is considered good/bad.
One sensor in the same room as my hub is -56.
The weakest and furthest away is -85.
I have just installed an ST zigbee outlet and I don't think its routing anything yet.
Just wondering what sort of figures I should be looking to achieve.
Thanks.

I would say -70 and below would be ideal, but even with devices in the -80's you should be fine. I believe once you get above -90 is where potential issue could arise.

31

Thanks for the info.
Ironically the ST outlet that I have just installed midway between my hub and the furthest zigbee device is showing the weakest signal. :slight_smile:
-93. Its not routing anything yet. Will be interesting to see if my mesh starts to throw a wobbly once anything routes through it.

32

Power? Smart EAS?

33

Is your hub on a UPS? With that collection of Xiaomi devices, I'd be afraid some would try to route through that outlet if they were to lose their connection to the hub. I believe the ST outlets aren't reliable repeaters for Xiaomi devices.
