The problem

I can’t get to display either rooms names or even texts with my Dreame D9. Rooms names are correctly retrieved (I’ve checked attributes and all ik OK), but there’s nothing on the map.

According to Pillow docs, using load_default() of ImageFont should use a default font is nothing is specified. This is what is doing the component: font = ImageFont.load_default()

But maybe no font can be used on Raspberry HASS (HomeAssistant OS 8)?

About the “texts” function, I’ve also tried using a font like that but it’s not working:

texts:
  - text: "My Room"
    x: 50
    y: 50
    font: "/local/fonts/Arial.ttf"
    font_size: 25

Room names are rendered when each label has a retrieved position, as far as I remember it works only for some Viomi models.

Your type of installation unfortunately doesn’t seem to have any built-in fonts and I haven’t had much success with loading ones from files as well.

This is what I thought, but that doesn’t work either. I’m using a custom card derived from Vacuum-Card, but I have to say that you did a wonderful job with the Map Card!
