There's a conflict due to the last commit to mqtt.homeassistant.

[t2000]

@fwolter I have rebased my changes and resolved the conflict.

[fwolter]

Constants should be all upper case.

[fwolter]

Normal members should be camelCase.

[t2000]

Thanks for the review, I have fixed the format error as well and rebased against the latest main branch too.

Does this work?
Don't we need a @SerializedName("state_topic") vor the deserialization to work?

[t2000]

Oh, yes!

Thank you very much. I have overlooked this and just blindly integrated the review comments as I knew they made sense in a way that there are styles on how to name variables.

I have created a small PR to fix this: #11550

Hi,
thank you for your contribution!

Could you please show where you found specification of status attributes, like time or usage counters?
I'm not 100% sure, but looks like these attributes were removed in latest Valetudo versions and they still exists only for Homie. Unfortunately, I'm far away from home and can't check this.
There is also lack of full support of Home Assistant mqtt.vacuum specification in your implementation.

I have a branch with mqtt.vacuum specification fully implemented: https://github.com/antroids/openhab-addons/tree/mqtt_vacuum
We could merge status attributes into the branch, if there is specification on them somewhere.

I have used https://www.home-assistant.io/integrations/vacuum.mqtt/ and he output of my valetudo running vacuum cleaners :)

You are right! Just when I had finished my implementation and when I was searching for possibilities to overcome the map rotation issues in the robots, I also saw that valetudo has changed the mqtt schema to homie. But that shouldn't be an issue, since we could also implement this too.

my implementation was never meant to cover 100% of any spec. I built it to support the robots out of the box with all the features I need. Feel free to add more, it is OSS.

I didn't know that. How can one know this if you do not leave a comment on the issue that I have closed? and why did you not create a PR yourself earlier or have commented on mine?

Anyway, feel free to add your stuff from your branch, which is missing in my implementation. I mean, in the end this is how OSS works, right? :)

Maybe you have a mqtt messages from new Valetudo version?
I would like to figure out how to handle these schema extensions, because they are specific for particular firmware version.
Maybe enable them based on manufacturer and topic prefix.
