Z2M 2.0 won't start | Home Assistant | Page 1

I've updated Z2M to 2.O from 1.4. I've read the breaking changes before I performed the upgrade.
My Z2M configuration.yaml contains:

    "adapter": zstack
    "port": "/dev/serial/by-id/usb-Silicon_Labs_slae.sh_cc2652rb_stick_-_slaesh_s_iot_stuff_00_12_4B_00_21_CC_47_C6-if00-port0"
  },
  "advanced": {
    "homeassistant_legacy_entity_attributes": false,
    "homeassistant_legacy_triggers": false,
    "legacy_api": false,
    "legacy_availability_payload": false,
    "log_level": "info",
    "pan_id": 6754,
    "channel": 11,
    "network_key": [```
The GUI gives: '502: Bad Gateway'
The log anyway shows:
```error:     z2m: Error: USB adapter discovery error (No valid USB adapter found). Specify valid 'adapter' and 'port' in your configuration.

#

The "port" line already existed. I've only add "adapter": zstack and also already changed to "adapter": "zstack"

#

I've checked the github link. It explains the add of adapter and port in the configuration...

#

The syntax with all " " (for example "serial" instead of serial) already existed in Z2M 1.4

#

Did you generate that YAML yourself? The way it's written, you need a trailing comma "adapter": zstack,

crystal atlas Jan 14, 2025, 6:54 PM

#

No the yaml was created by the previous Z2M version

west orbit Jan 14, 2025, 7:00 PM

#

What added the line "adapter": zstack then?

#

Reread, you did

#

try with the comma

crystal atlas Jan 14, 2025, 7:08 PM

#

Tried with comma, restarted HA completely but same error

Strange because in the log I see data from devices:

But the GUI gives 502: Bad gateway

I was not able to solve the problem and downgraded to V1.4. Restarted HA and Z2M works without any issue.
Checked the configuration.yaml and it still has the revised configuration.yaml file with "adapter" and "port".
Why Z2M works on V1.4 and won't start on V2.0

earnest meteor Jan 15, 2025, 8:29 AM

#

Please share the new Z2M configuration YAML

#

Thanks @earnest meteor

earnest meteor Jan 15, 2025, 7:58 PM

#

What on earth is that?

crystal atlas Jan 15, 2025, 7:59 PM

#

Euh, what do you mean

#

The code or the link?

earnest meteor Jan 15, 2025, 8:00 PM

#

The Z2M config is YAML, not JSON

crystal atlas Jan 15, 2025, 8:01 PM

#

I use Z2M since few years. Never touched the configuration.yaml. I'm not a programmer, so I suppose, years ago it was generated automatically. It remained working till 2.0 came. The file works with Z2M 1.4

#

So for 2.0 I've added the content on top of this thread

#

Based on https://www.zigbee2mqtt.io/guide/configuration/ the file should be in the data folder. I took and revised the configuration.yaml from /config/zigbee2mqtt/configuration.yaml.

Changed configuration.yaml from Z2M to https://codeshare.io/R7qoz4
Restarted HA and Z2M worked on 1.4.
Upgraded to 2.0.0.2 and restarted. Z2M gives again bad gateway.

#

Anyone able to tell me how to find the correct serial adapter. Seems maybe something has been changed

crystal atlas Jan 15, 2025, 9:18 PM

#

Again downgraded to 1.42.0.2 with old configuration file and Z2M works again.

earnest meteor Jan 15, 2025, 10:02 PM

#

Yeah, that points to the config not being right - did you check the 2.0 release notes and the link in the error above?

crystal atlas Jan 16, 2025, 6:17 PM

#

Yes, I did, prior to the upgrade and once more after 2.0 won't start...

#

The USB dongle is no longer detected in 2.0 and it works in 1.4. The only thing for that I've added adapter: stack

crystal atlas Jan 17, 2025, 5:42 PM

#

Hi, any idea how to run Z2M 2.0 with my USB dongle?
