The problem

Followed the docs to workout zone coordinates but seem to get bad data (number much lower than examples).

Additionally when using these numbers the zone does not show up in any way.

{
  "domain": "xiaomi_miio",
  "service": "vacuum_clean_zone",
  "serviceData": {
    "zone": [
      [
        2,
        -1,
        4,
        1
      ]
    ],
    "repeats": 1,
    "entity_id": "vacuum.waffle"
  }
}

I'm currently using this integration for the vacuum and your other one for the camera

I believe the vacuum is a STYJ02YM aka viomi.vacuum.v8.

Followed the docs to workout zone coordinates but seem to get bad data (number much lower than examples).

there are two coordinate systems: Xiaomi and Roborock vacuums use millimeter-based (~25500), Viomi use meter-based one. You have to change platform (e.g. to viomise) in card's config to change coordinate system

[dogmatic69]

Ok I'm struggling to follow what you saying. I've tried changing platform on the card but viomise was not valid. I tried some others listed in the read me and then the data changed to x.xxxxxxxxx, I guess meters but with decimals.

I got it showing the defined zones now but seems it's not possible to select individual zones. will have to keep digging.

Anyway if you look at the screen shot out the box with no platform set even if it was meters the measurement always shows as 0.0m x 0.0m

That's also because of platform and coordinate systems.

It seems that integration you use doesn't support zone or segment cleaning, is it true? https://github.com/nergal/homeassistant-vacuum-viomi/issues/30 https://github.com/nergal/homeassistant-vacuum-viomi/issues/34
