Connection problems with ZHA

@TheSmurf

Im a bit confused now.
If I open the github respository (silabs-firmware/EmberZNet at main · NabuCasa/silabs-firmware · GitHub) there is version 7.1.0.0.
As you said Í should downgrade to the latest 7.1.x.x. version I looked inside the archive and found 7.1.3.0 in the archive.
Putting something inside the archive looks like sayin “its there, but better dont use”.
Which version you recommend?
Edit: as the flashing website tells me, that there is nothing wrong with the firmware the stick was shipped with - Im going for 7.1.0.0.
This should be better than what I have, and flashing to another version (if you recommend anything else) isnt that hard.

That is how intepret it too, if it is in archive then it is not recommended, (so my guess is that they have first had that under the beta directory but then it was proven not to be as stable as older version so they moved it to archive instead).

I also suggest that you go with the 7.1.0.0 version for now, (though you can keep an eye on the beta directory too as expect that will probably see that a newer 7.3.x.x will become new stable sooner rather than later)

But if you do want to experiment with later version today then check out thee unofficial (NCP) community builds by darkxst that are very popular among testers and early adopters → silabs-firmware-builder/firmware_builds/skyconnect at main · darkxst/silabs-firmware-builder · GitHub

Have you tried changing to a different Zigbee channel after checking WiFi channels neighbors uses?

@TheSmurf

I know my zigbee is running on channel 11. Thats all I know.
If the firmware downgrade doesnt change anything, ill take a look at the channels (and try to understand whats happening there)

So you are saying that you did not read the guide and are not followng the best practice tips there

At the very least read this → ZigBee and Wi-Fi Coexistence | MetaGeek

Can you at least check your own WiFi-router or WiFi access-point(s) what WiFi channel(s) are using? While logged into it you should make sure it is set to a static channel and not to auto so it won’t change.

Preferably also install a free WiFi-survey/scanner app (like WiFiman by Ubiquiti) on an Android-based phone or tablet and have it quickly analyze what WiFi channel(s) your neighbors are using and what strength they are so you with that knowledge can make a choice to avoid those too if their signals are strong.

Zigbee and Wi-Fi channel numbers may seem similar but they are not. So if you are for example are using Zigbee channel 11 as you said then you and your neighbors should preferably not be using the overlapping WiFi channel 1 (which is the most commonly used WiFi channel and hence it is generally a bad idea to use Zigbee channel 11 to 14.

The general best practice is to use Zigbee channel 15, 20, or 25 (if you only have newer Zigbee 3.0 devices then Zigbee channel 26 is an option but should be avoided if have any older Zigbee devices).

If you are using Zigbee channel 15, 20, or 25 then you want to lock down your WiFi to it is set to static channel (not auto) and only using WiFi channels 1, 6, or 11 as you get the least overlap with Zigbee.

If possible talk to your neibors to lock down their WiFi to static as well (also using WiFi channels 1, 6, or 11 but not the same WiFi channel as you are using).

Personally I will not be help you anymore here until you actually done your best to follow my guide:

• Zigbee networks: how to guide for avoiding interference + optimize using Zigbee Router devces (repeaters/extenders) to get a stable Zigbee network mesh with best possible range and coverage by fully utilizing Zigbee mesh networking

I mean, why should we spoonfeed you here a trickle at a time when you can not be bothered to read and try your best to take action in following those best practice tips to help yourself. Help us help you!
