MQTT not working in HomeAssistant

[R0SSI89]

I can't get the MQTT working with Home Assistant. I get the following error in the HomeAssistant logs. This happens when I add new alias in the milight interface.

Home Assistant log output:

Additional context

First time using this and it would be great if I get it working (if I find some time I will provide some updates to the wiki)

[bluebier]

i get the same error

[sidoh]

Hey @R0SSI89 and @bluebier, which version of HomeAssistant are you guys using? I'm guessing this field was added in recently. I had hoped it'd add a link to the config page in the HA UI but it didn't, so probably safe to remove it.

[KRiZ-R]

Hi @sidoh, first time user here, and I have the same issue. I am using the latest version of Home Assistant:

Home Assistant 2023.9.3 Supervisor 2023.09.2 Operating System 10.5 Frontend-versie: 20230911.0 - latest

[R0SSI89]

@sidoh I added the HA version information in the issue, but it's the latest. I saw a lot of changes in the MQTT in HA, not sure if this could be the issue (I'm not a programmer, but a system engineer).

[sidoh]

Thanks, guys. Will take a look. I'm also on 2023.9, so a little strange that I'm not seeing it.

[sidoh]

Oh wait, this is showing up for me too, but it's a warning. Is it not a warning for you guys?

[R0SSI89]

Yeah you're correct, so I guess not a bug.. Maybe a misconfiguration, but where :(

[sidoh]

Do you see an entry in Settings > Devices for espMH? It should be named the same thing as what you have the hostname configured to.

If you do, can you show me a screenshot of what yo usee there?

[KRiZ-R]

Yes it is a warning in the logs. It does not add the device under Settings > Devices

[sidoh]

Gotcha. That's likely the cause. Will try to reproduce and get back to you guys.

[R0SSI89]

For me it isn't either not showing under Settings > Devices.

[R0SSI89]

Not suer if it helps, but these log lines appear in the Mosquito Broker logs when I remove a paired bulb and add it again (using the same device ID and group as the remote).

[R0SSI89]

Ow and changed the MQTT state topic pattern to (compared to the settings provided when I created the issue):

milight/states/:hex_device_id/:device_type/:group_id

[R0SSI89]

I got a notification about a new update: 2023.10.0. Should I try this update?

[garmck]

Do you see an entry in Settings > Devices for espMH? It should be named the same thing as what you have the hostname configured to.

If you do, can you show me a screenshot of what yo usee there?

This happened to me last weekend after I decided to start fresh, but hadnt got round to troubleshooting. (also shows IP adddress for URL) @sidoh I suspect this is broken for new/fresh installs - I also suspect it wont add new aliases showing up for existing working installs.

[garmck]

I got a notification about a new update: 2023.10.0. Should I try this update?

I suspect it wont take @sidoh long to resolve this. But if you urgently need it working, you can manually add your lights using the MQQT Light component https://www.home-assistant.io/integrations/light.mqtt/#json-schema---examples

[R0SSI89]

I'm not in a rush, I've got it "working" via the official Wifi box, but I want to make it a little smarter ;)

Thanks for the quick responses!

[sidoh]

Taking a peek now. Thanks all for the extra info.

Don't expect a new version of HomeAssistant will help anything. I think I just mangled the discovery json a bit. (in my defense, the docs are kind of hard to parse).

[garmck]

Here's how another integration shows in MQTT

This is the current MiLight MQTT

[sidoh]

Yeah, o is supposed to be a supported abbreviation of origin according to the docs. Maybe all of these fields need to be filled out? In any case, I couldn't really figure out what the function of this data was, so I just removed it.

I'd hoped it would add a link in the device dashboard to the config page, but it didn't have that effect.

[sidoh]

I believe this guy will fix the problem: https://github.com/sidoh/esp8266_milight_hub/pull/805

I tagged a beta release. Will publish that when the build finishes for you guys to try out.

[sidoh]

https://github.com/sidoh/esp8266_milight_hub/releases/tag/1.11.1-beta1 give this guy a try

[garmck]

Just loaded this version and can confirm the MQTT discovery is now adding devices as expected for myself.

[R0SSI89]

Will try the beta tonight (I'm from the Netherlands). Thanks @sidon 😄

[KRiZ-R]

Just did a quick test before getting ready to work, and it works! It shows new devices immediately. Thank you!

[sidoh]

Nice, thanks for confirming, guys! I'll merge this and cut a release. LMK know if there are any issues :)

[sidoh]

Fixed in 1.11.1! Thanks everyone for the thorough reports.

(no difference in 1.11.1-beta1 and 1.11.1 except the version tag/metadata.)

[R0SSI89]

Thank you, it works now!
