Hey!
Does any one know how to make SkyConnect ( I have the latest one ) work in EMBER mode for Zigbee2MQTT ?
There is information that eszp is depreciated
"zh:ezsp: 'ezsp' driver is deprecated and will only remain to provide support for older firmware (pre 7.4.x)"
and switching to EMBER I got an error:
"error: z2m: Error: Adapter EZSP protocol version (9) is not supported by Host [13-14]"
Thank you!

Update the firmware on the stick

lost mural Dec 9, 2024, 10:42 AM

#

Can I do it w/o loosing the warranty ?

glad forge Dec 9, 2024, 10:42 AM

#

Yes

#

You're expected to do that 😉

lost mural Dec 9, 2024, 10:43 AM

#

ok. Can you give me a link with info how to do it step by step, please ?

#

Nabu Casa claims that I do not need to make any firmware updates cause they will do them automatically...

glad forge Dec 9, 2024, 10:44 AM

#

I'm guessing you didn't check the Z2M docs 😉

As far as I know that automatic update is a future thing, at best

#

They were talking about it arriving in 2024.12, but now that's more likely to be 2025.01, depending on what it actually does

#

Automatically updating firmware though ... that's pretty damn brave

lost mural Dec 9, 2024, 10:49 AM

#

Is there any flashing software to do so? Their WebFlasher looks liek this: The firmware update is temporarily unavailable.

glad forge Dec 9, 2024, 10:49 AM

#

That web flasher was taken down, don't remember why, but HA's "native" one was supposed to replace it

#

However, did you look at the link I posted?

#

I can see multiple web flashers and multiple command line tools listed there

#

There's even an add-on if you run HAOS

lost mural Dec 9, 2024, 10:50 AM

#

ah... I will take a look into HAOS

#

Silicon Labs Flasher ?

#

I go an error:
Error: Failed to probe running application type

s6-rc: warning: unable to start service universal-silabs-flasher: command exited 1

#

FYI: I am using SkyConnect via Proxmox ( but it works with HA properly )

#

I got this result:

#

Does Code 0 mean SUCCESSFULY FLASHED ?

glad forge Dec 9, 2024, 10:59 AM

#

Is that from the add-on?

#

I'd guess that means it works, but the way to tell is to check what Z2M says the firmware version is

lost mural Dec 9, 2024, 11:01 AM

#

yes

#

I have checked ( doing seconf update ) that the version before flashing is now: 7.4.4.0.0

#

So it looks like flashed, right ?

glad forge Dec 9, 2024, 11:01 AM

#

Yes

lost mural Dec 9, 2024, 11:01 AM

#

ok. Thank you. I will try now the Z2M ember

#

Why they didn't do it when releasing from the factory ? hmmm.... :)_

glad forge Dec 9, 2024, 11:02 AM

#

It probably was, but that could have been months ago

#

Actually, if that's a SkyConnect then it was a long long time ago

lost mural Dec 9, 2024, 11:03 AM

#

This is the newest release after Voltage Controller ( or sth ) update

glad forge Dec 9, 2024, 11:03 AM

#

No idea then

#

You should feed that back to Nabu Casa 😉

lost mural Dec 9, 2024, 11:03 AM

#

ha ha... it is hard... they are directing you HERE , to Discord 🙂

#

looks like it work in EMBER.
Got just a single error when Z2M was starting:
error: zh:ember:uart:ash: Received ERROR from adapter while connecting, with code=RESET_WATCHDOG.

#

But I can see all "the typical movement" in logs

#

Thank you for your SUPPORT !

#

Just one question about MQTT QoS:
It is better to set it to 1 ?
I see that sometimes I got some problems whit Power Plugs enablig/disabling after using Zigbee switch.
There is no reacion or few seconds latency util the end device reacts.

#

anyways. Thank you once again !
