Error -3 while decompressing data: incorrect header check while trying Viomi S9

[fokcuk]

Hello
I am trying to get maps for Viomi S9 urn:miot-spec-v2:device:vacuum:0000A006:viomi-v18:1
When I configure the parameters and restart HA I get this error:

This vacuum uses roidmi map format, related issue: #127

[PiotrMachowski]

You can now check out version from this branch

[fokcuk]

not sure where I went wrong:

What is your config?

[fokcuk]

redownloaded but still get the same issue.
This is what I have in the config:

  - platform: xiaomi_cloud_map_extractor
    host: !secret xiaomi_vacuum_host
    token: !secret xiaomi_vacuum_token
    username: !secret xiaomi_cloud_username
    password: !secret xiaomi_cloud_password
    country: sg
    force_api: viomi

It also did not like(said it did not suport) store_map: true that I had there before, so had to comment that out

[PiotrMachowski]

You have to remove "force_api" section, as your vacuum doesn't use viomi map format. Everything should be auto-discovered now.
store_map has been changed to store_map_raw

  - platform: xiaomi_cloud_map_extractor
    host: !secret xiaomi_vacuum_host
    token: !secret xiaomi_vacuum_token
    username: !secret xiaomi_cloud_username
    password: !secret xiaomi_cloud_password
    country: sg

[fokcuk]

great! Can see map now, just need to add more options

[PiotrMachowski]

Oh, use this config:

  - platform: xiaomi_cloud_map_extractor
    host: !secret xiaomi_vacuum_host
    token: !secret xiaomi_vacuum_token
    username: !secret xiaomi_cloud_username
    password: !secret xiaomi_cloud_password
    country: sg
    draw: ["all"]

[fokcuk]

yep, that is what I needed =)

[fokcuk]

can you please also tell me how to do this?
xiaomi_cloud_map_extractor.reload

[PiotrMachowski]

You should have a button for it in "Server controls" page
