Matter over Thread Best Practices

[tacit temple]

Hi all, I am trying to migrate my old lights (hue v1, first generation tradfri etc) to thread lights (mostly ikea bulbs and battery powered end devices). I have two different zigbee mesh in my home (one of them is hue and other one is zigbee2mqtt via zzh).

Right now I have 3 apple homepod mini, 1 apple tv and one nest hub and they are in the same network in the home assistant. (see picture)

Unfortunately my end devices and also bulbs lost it's connection from time to time and sometimes lights turn on automaticly when bilresa remotes connect to network again. I assume that 5 border routers will create a basic mash network but I am not so sure that.

So Is there any missing point as in the terms of best practices or should I just add more bulbs / plugs to system to improve the mesh reliability?

Thanks,

Did you read about the IKEA issues on GitHub? They seem to be enddevice/firmware related.

2.4 GHz WiFi, Zigbee, Thread and Bluetooth all share/use the same 2.4GHz frequency band. Did you plan your channels for WiFi 2.4GHz, your two Zigbee and your Thread network? Which channels are in use?

Zigbee and Thread use the same channel scheme. Read this:

@nocturne meteor thanks for your answer I already try to update beta firmwares of ikea devices but I will be glad if you can share any updated github issues. I already suspect from a interference between channels but I can't figure how can I change the thread channel from Home Assistant

Apple HomePods use Thread channel 25. You can’t change that the easy way. Don’t use 2.4GHz WiFi channel 11. Its side lobes can interfere with Thread channel 25. You can change the Zigbee channel via settings of your HueBridge to channel 11, 15, 20 or 25. Hue devices change the channel too, when you change the Zigbee channel on your HueBridge. Don’t use Zigbee channel 25. It interferes with your Thread channel 25. You can also change your Zigbee channel of your Z2M. But be careful. Not every device accepts a channel change. You maybe have to re-pair some your devices. Don’t use the same Zigbee channels for your HueBridge and your Z2M.

Look here at the open and closed IKEA issues: You will find something relevant. I do not own IKEA Matter over Thread devices (EVE, Aqara, Philips Hue only).
