SLZB-06 and Home Asist. wont talk to eachother... | Home Assistant | Page 1

Hey Guys,

im having issues to get Home Assistant and Zigbee-Devices Working on my Setup:
Raspberry Pi4 - Home Assist.
Mosquitto broker
Zigbee2MQTT
SLZB-06 as Dongle over Ethernet

I see the Test-Device (a simple door switch) in the "Zigbee2MQTT - Dashboard". Exposes are there and working.
So the pure Zigbee Connection to the SLZB-06 is working AND the Zigbee2MQTT - Plugin is talkig to that dongle.
But i dont see the Exposes or any other sign of that Doorswitch in Home Assist. Nothing in the MQTT Tab, no "New Device"-Message. Just nothing.

The Funny thing:
other MQTT-Devices, like my Solar-Inverter and some Tasmota-Plugs, are just working fine.
But they are talking over Wifi.

So, for my understanding:
Mosquitto broker -> Raspberry Pi4 - is working (see the Tasmotas and SolarInverter)
Zigbee2MQTT -> SLZB-06 -> Device - is working, cause i can see the Device, and can rename it, an things...

im guessing that the Zigbee2MQTT-Plugin is not talking to the Mosquitto broker.

in the Zigbee2MQTT-Logs i see
[2025-10-16 18:33:55] info: z2m: Connecting to MQTT server at mqtt://192.168.2.254:1883
[2025-10-16 18:33:56] info: z2m: Connected to MQTT server

in the MosquittoBroker-Logs i see
2025-10-16 18:33:56: New connection from 172.30.32.1:37542 on port 1883.
2025-10-16 18:33:56: New client connected from 172.30.32.1:37542 as mqttjs_43ce2ca2 (p2, c1, k60, u'mqttuser').

now im really an the End of my Knowledge.
They Should talk to eachother, but i dont see the Devices?
What should i do?

Check these settings in Z2M:

#

Note the the second checkbox is disabled by default

balmy zenith Oct 16, 2025, 4:49 PM

#

this is the settingspage

#

if i try to change a thing, i get the message:

#

z2m: Request 'zigbee2mqtt/bridge/request/options' failed with error: 'Extension with name HomeAssistant already present'

molten frost Oct 16, 2025, 4:50 PM

#

well, "ham" isn't right 🙂

#

that name matters

balmy zenith Oct 16, 2025, 4:50 PM

#

ohh ok

molten frost Oct 16, 2025, 4:51 PM

#

stick with the defaults

balmy zenith Oct 16, 2025, 4:51 PM

#

so, how to change that? if i type the defaults in there it throws:
z2m: Request 'zigbee2mqtt/bridge/request/options' failed with error: 'Extension with name HomeAssistant already present'

molten frost Oct 16, 2025, 4:52 PM

#

got this from a Google search: https://community.home-assistant.io/t/z2m-setting-home-assistant-legacy-action-sensors-failed-with-error/875150

#

I've never seen that error before, but you can change it in the configuration.yaml for Z2M (not the one for HA)

balmy zenith Oct 16, 2025, 4:53 PM

#

hmm strange:

#

molten frost Oct 16, 2025, 4:53 PM

#

see the last message here? https://www.reddit.com/r/homeassistant/comments/1k7kdpv/new_zigbee2mqtt_devices_not_discovered_in_ha/

#

that doesn't reflect what you posted in the UI

balmy zenith Oct 16, 2025, 4:55 PM

#

exact, strange

#

ahm

#

ill shut down the plugin, write the yaml and test again?

molten frost Oct 16, 2025, 4:55 PM

#

you should shut down the addon, edit the YAML, and start the addon

balmy zenith Oct 16, 2025, 4:56 PM

#

2 seconds, ill do so

#

ok, now it fits

#

but still cant find that zigbee device

molten frost Oct 16, 2025, 5:04 PM

#

does the device expose anything in Z2M? Do you see status there?

balmy zenith Oct 16, 2025, 5:04 PM

#

yes, under "exposes" i can see the switch switching if i switch the switch (!?!)

#

see

molten frost Oct 16, 2025, 5:27 PM

#

If you're not seeing the device under the MQTT integration, I suggest going into the MQTT integration page, hitting configuration , and listening to homeassistant/# to see if messages are coming in when you change the state of that sensor

balmy zenith Oct 16, 2025, 5:28 PM

#

ahm... wait i can follow

#

ohhh

#

ok

#

i hear the switch:

#

wait

#

no thats the bridge

#

ok, its talking:

molten frost Oct 16, 2025, 5:32 PM

#

then it's highly likely that you have a device coresponding to that in teh MQTT integration page

balmy zenith Oct 16, 2025, 5:33 PM

#

sadly no

#

well of course i can see the bridge, but not the doorswitch

molten frost Oct 16, 2025, 5:34 PM

#

you can try reloading the MQTT integration or restarting HA

balmy zenith Oct 16, 2025, 5:34 PM

#

okay, gimme a second

#

sooo, a reaload did nothing, ill try to reboot the raspi... this will take a while.....

molten frost Oct 16, 2025, 5:38 PM

#

You can also use MQTT Explorer to find the topic and see if the value looks sane. I don't know why it wouldn't be discovered

#

one of mine looks like this:

{"availability":[{"topic":"zigbee2mqttp/bridge/state","value_template":"{{ value_json.state }}"}],"command_topic":"zigbee2mqttp/FR Table Lamp/set","default_entity_id":"switch.fr_table_lamp","device":{"hw_version":1,"identifiers":["zigbee2mqtt_0x282c02bfffeb4567"],"manufacturer":"Third Reality","model":"Zigbee / BLE smart plug","model_id":"3RSP019BZ","name":"FR Table Lamp","sw_version":"v1.00.98","via_device":"zigbee2mqtt_bridge_0x00124b0024c3d377"},"name":null,"object_id":"fr_table_lamp","origin":{"name":"Zigbee2MQTT","sw":"2.6.2-dev","url":"https://www.zigbee2mqtt.io"},"payload_off":"OFF","payload_on":"ON","state_topic":"zigbee2mqttp/FR Table Lamp","unique_id":"0x282c02bfffeb4567_switch_zigbee2mqttp","value_template":"{{ value_json.state }}"}

balmy zenith Oct 16, 2025, 5:42 PM

#

well, raspi is back online, but nothing has changed. still no door sensor

#

ill give that MQTT Explorer a try

molten frost Oct 16, 2025, 5:45 PM

#

I suggest also reviewing the HA logs to see if it's complaining about it

balmy zenith Oct 16, 2025, 5:45 PM

#

ahm

#

bingo

#

📎 message.txt

#

what is "extra keys not allowed" ? what is an extra key?

molten frost Oct 16, 2025, 5:47 PM

#

seems like something about model_id, but mine has that too

#

could be a bug in Z2M for that device

balmy zenith Oct 16, 2025, 5:48 PM

#

or could be the "/" in 'model': 'Door/window sensor'

molten frost Oct 16, 2025, 5:48 PM

#

oh, could be

#

but I have one of those too

#

you can't control that

balmy zenith Oct 16, 2025, 5:49 PM

#

yes, and your stuff works, so i dont think its the issue

molten frost Oct 16, 2025, 5:49 PM

#

what version of HA and Z2M are you using?

balmy zenith Oct 16, 2025, 5:49 PM

#

ahm

molten frost Oct 16, 2025, 5:49 PM

#

old HA version?

balmy zenith Oct 16, 2025, 5:50 PM

#

Zigbee2MQTT
Aktuelle Version: 2.6.2-1

aaand the HA version is....

molten frost Oct 16, 2025, 5:50 PM

#

https://github.com/Koenkk/zigbee2mqtt/issues/26021

#

At least HA 2024.9 is required for Z2M 2.0.0 (see https://github.com/Koenkk/zigbee2mqtt/releases/tag/2.0.0)

balmy zenith Oct 16, 2025, 5:51 PM

#

where is the Version number stored??

molten frost Oct 16, 2025, 5:51 PM

#

configuration -> About

balmy zenith Oct 16, 2025, 5:51 PM

#

ohh

#

got it

#

ore 2024.7.1
Supervisor 2025.10.0
Operating System 16.2
Frontend 20240705.0

molten frost Oct 16, 2025, 5:51 PM

#

so, ancient

#

update your HA

balmy zenith Oct 16, 2025, 5:51 PM

#

ok

#

if i chek on updates, its not showing any updates, so i guess i have to ssh into the raspi and upgrade it there?

molten frost Oct 16, 2025, 5:54 PM

#

you can. https://www.home-assistant.io/common-tasks/os/#updating-home-assistant-core

if you have further issues, please post in #1284966540617449515 for help

balmy zenith Oct 16, 2025, 5:54 PM

#

👍 thanks

balmy zenith Oct 16, 2025, 6:29 PM

#

guess what:

it worked

#

i always thought, that updating via GUI was all i have to do.

if we ever meet in RealLive, all your Beer are paid by me. Thanks
