VIOMI Alpha 2 Pro

[viotemp1]

Hello,

Do you think is possible to add support for VIOMI Alpha 2 Pro (viomi.vacuum.v22)?
The card with camera does not display any map and the message is Invalid Calibration, please check your configuration.

The config is:

  - platform: xiaomi_cloud_map_extractor
    name: viomi_alpha2pro_vacuum_map
    country: de
    host: !secret viomi_alpha2pro_vacuum_host
    token: !secret viomi_alpha2pro_vacuum_token
    username: !secret xiaomi_cloud_username
    password: !secret xiaomi_cloud_password
    force_api: viomi
    scan_interval: 60
    draw: ['all']
    attributes:
      - calibration_points
      - rooms
      - room_numbers
      - vacuum_room
      - vacuum_room_name
      - cleaned_rooms
      - zones

I see these messages in the home assistant log:

Have you tried using other APIs? Some Viomi vacuums work with roidmi API instead

Hello,

Thanks for your answer, indeed it works with roidmi.
