Document new vacuum features (goto, zoned cleaning)

[SebRut]

Recently the Mi Home App added support for region cleaning and navigation to target like the V2 for V1. Is support planned for these features and is there any way to help develop these?

At the moment there is no easy way to get a map / coordinates from a non-rooted device, and the map itself is generated on the fly for new runs, meaning that the coordinates may change between runs. What we could do is to add those commands (move to X, start cleaning region X,Y) if someone figures out how they work, but the problem with the coordinates is harder to solve, so I don't see this happening very soon.

home-assistant/core#13879 The commands are app_goto_target and app_zoned_clean apparently, as mentioned in additional information of that issue.

When the map is created first, the starting location of the coordinates (where the robot sits at this moment) are always [25000,25000] (or really close to that) and the rest of the map is then build around those coordinates.
On the app you can then share/save the map (once it's complete). Use the "app_goto_target" command to figure out how much your robot moves with each coordinate change. Then create a grit with those coordinates on your image of the map and you can start creating areas/rooms. Here is an example of what I mean: map
In theory - since the robot always starts from the same point and the map should not change as long as you don't move the station, this should work. It's a little bit of work, but other users from OpenHab/iobroker have reported that it works great. They had issues with the map randomly rotating 90 degrees, but that seemed to only affect a few people.

Ah, got it. The rotation may have been a bug that has been fixed in newer FW releases (or could be fixed in upcoming ones). I'm open for PRs to add the necessary support, of course.

Im a complete newbie, I have only used guthub passively so far and never programmed in python. I gave it a shot anyway. So don't be too hard on me :) #310

[rytilahti]

Thanks for the PR, it's now merged! I think it would be nice to have your description on how to get & calculate the coordinates in our docs, so if you want to do some writing, it would be really helpful to have a link to point users asking how to use those :-)

[ciB89]

Sure, I'll see to it :) Might take some time though, I'm really busy the next couple of days.

[rytilahti]

Any update on this? Any ideas on #355?

I'm really sorry, I've recently accepted a new job offer which is currently eating all of my time.. it's on my list, but I honestly can't tell when I have time to write something up. I think I can help with the referenced issue though.
