Error "Invalid calibration" when using Map Extractor

[cranxi]

Hi there, first of all thanks for all your time in making this card.

I tried to set-up the card by using the map extractor. When following the instructions I'm getting the error in the card: "Invalid calibration, please check your configuration".

The code so far:

type: custom:xiaomi-vacuum-map-card
title: Xiaomi Vacuum Map Card
preset_name: Live map
entity: vacuum.hanna
vacuum_platform: KrzysztofHajdamowicz/miio2
map_source:
  camera: camera.xiaomi_cloud_map_extractor
calibration_source:
  camera: true

The map extractor is working, I got the Roborock map in Home Assistant:

Not sure what I'm doing wrong here.

Thanks!

Darryl

You probably have to add following section to config of Map Extractor camera:

attributes:
  - calibration_point

[PiotrMachowski]

As far as I remember it is mentioned in docs of Map Extractor

All the way on the buttom it says indeed calibration_points - Calculated calibration points for Lovelace Xiaomi Vacuum Map card.

Not so clear at the install instructions but it is working now, thanks!

I have to improve my docs, they are far from perfect

[cranxi]

For someone who relies on instructions, maybe haha

I am also struggling with this error "Invalid calibration, check your configuration".
I believe the correct syntax is:

attributes:
  - calibration_points

Note the extra s at the end.
