Nabu Casa ZBT-2

[Oldefa1985]

Hi,

I think i need some help, i used to have the Skyconnect adapter, which worked fine, but i decided to try to upgrade to the ZBT2.
I managed to get pretty much everything back after a long and hard struggle.

However it seems to keep crashing my Z2M

z2m: Failed to ping 'Udenfor-Væglampe-Garage-Højre' (attempt 1/1, ZCL command 0x00178801067f1499/11 genBasic.read(["zclVersion"], {"timeout":10000,"disableResponse":false,"disableRecovery":true,"disableDefaultResponse":true,"direction":0,"reservedBits":0,"writeUndiv":false}) failed (sendZclFrameToEndpointInternal error))

zh:ezsp:uart: --> Error: Error: {"sequence":-1} after 10000ms

zh:ezsp:uart: Failed to reset on Error Frame: Error: Reset error: Error: {"sequence":-1} after 10000ms

zh:ezsp:uart: --> Error: Error: {"sequence":1} after 4000ms

zh:ezsp:uart: -!- break waiting (1)

It seems to keep flipping my Z2M with restarts.

I have tried several firmware 7.4.4.3, 7.4.4.5 and 7.4.4.6 (current)
My Z2M version is 2.6.3

Im using EZSP v13
adapter: ezsp
baudrate: 460800
disabled_led: true
port: my device ;)
rtscts: true

When i look into Nabu Casa's documentation i seem stumble upon that they're recommending the ember adapter, but i simply cant make it work properly since it spams this in the logs

I have probed with the universal-silabs-flasher both outside my LXC in Proxmox and inside my LXC and it works fine.

What am i doing wrong?

It also seems to have a distaste for the Hue Appear outdoor lamps.

No real answer here but I have the same problem. Can't find any answers on the web

[Oldefa1985]

same here .. im just told to read the migration guides (which i have) - it seems VERY unstable

I actually just put back in my ZBT-1 and everything worked like a charm with better coverage, performance and stability

[Andrew6003]

Oh really, I may have to do this, it's annoying I'm not home and wife is and things just keep dropping off left right and center for no reason.

Did you try and copy the ieee address over to see if that had any effect.

[Oldefa1985]

Well no i havent actually - however i dont see it being the reason behind the instability.. i readopted several of my devices, and they were just as unstable both before and after - either the stick itself is very bad, or the firmware is.

I know the feeling about the "wife thing" :D

You are using the old ezsp driver, it's recommended to use the new ember drivers (info)

[Andrew6003]

The the original op may be, but I'm using the ember driver and still having these issues.

[Oldefa1985]

I have been using the ember driver as well, which gives me all the route errors - and not only one - like ALOT! - furthermore its VERY unstable.. i can make a light work, after reboot and waiting its permanently offline until i reset it again.
