FR: override the "static" background image "under" the Vacuum route

[java-devil]

First of all: Amazing work!

Second of all: Amazing work! You Sir should take satisfaction in that you personally removed major pain-points for the adoption of HA. Make no mistake - seamless support of the biggest vacuum brand is on itself a major boon for the entire platform 🥳

I will follow these words up with several coffees on your behalf ;)

Context

My request is trivial in comparison with the work you already did. I happen to be autistic and the graphical glitches rendered by the Roborock map are insufferable to me.

To help convey the problem - I took the effort to "tidy up" my map.

The Need

Please consider the ability to override the static background image, while preserving the calibration points + the ability to overlay the vacuum route over the map + the vacuum position + the dock position.

If need be I am willing to submit a PR if you would be as kind as to point me to the broad area of the code that needs to be modified ;) I'm not even sure if this is the proper repository ;)

Consider that more and more people in the HA community are creating custom maps of their apartment (often styled in the likeness of 8-bit RPGs, often via the use of LLMs). So this isn't a one-person-only functionality ;)

First, Thank you very much for the coffees :)

This is something i have thought of - but not something i've had the time to get done! It wouldn't be too hard of a task just take some time. So up to you if you'd like to work on it or if you want to wait for me to get it done - I have a few key stability changes i am taking care of first but I could move it to the top of my list after that.

Basically, the options flow needs to have a new step 'async_step_colors' it would follow the same flow as the drawables section: https://github.com/home-assistant/core/blob/dev/homeassistant/components/roborock/config_flow.py#L218 . Except, for each Color in the default colors, we would want to have a color picker and then a number picker from 1-255 that would control transparency. Then the first step of the options flow would need to open a menu to select which step you want, drawables or colors.

You would then create a tuple for each color based on the color selected, and the transparency. i.e. (R, G, B, T)

Then, the information would be passed to the MapDataParser in the colors section here here: https://github.com/home-assistant/core/blob/38bf06e17924bddf8266ce341a645ae95cc174b0/homeassistant/components/roborock/coordinator.py#L149

I am happy to get this done, i unfortunately need to finish the current things i am working on first though.

If you wanted to work on it, you could just make the MVP and then I could make the tests, or I could make a skeleton for you. (just some print statements on where you need to do things). Or really whatever you'd like. If you don't want to work on it, then I just ask you give me a little bit of time to wrap up the current thing i'm working on!

Once this exists, then I think it would be the responsibility of a custom integration to make it easier to add a background image. This repository would be a good first or the lovelace card itself. But that will only be possible once it is possible to make things transparent.

Hey,

This is an amazing write-up. Truly.

I'm currently a rather overwhelmed Java-Dev-Before-Major-Release-Dad-of-Two by day, so it would take me considerable time to even get working on this, and then I would still have to get it working in an idiomatic python way.

TBH when I proposed a PR I was thinking that otherwise you won't ever find the capacity to entertain such a "1-st world problem" request ;) And that eventually I will be able to pick this up.

Proposal still stands ofc, but for the sake of the sanctity of your code-base I would prefer not to tarnish it with my "work" if this functionality is anywhere remotely on your radar.

Does that make sense? :)
