Problem

I can confirm that the map gets extracted from my viomi.vacuum.v8 but the Python script fails to parse it due to failing the integrity check: ValueError: error parsing section unknown2 at offset 0xee644: magic check failed. Magic: 0x1933800, Map ID: 0x0

Duplicate of #153

Potentially it will disappear after a few full cleanings

othmanalikhan commented 1 year ago

I'm not sure whether it is because of the refactoring or whether because I re-generated the map couple of times. But the issue is now resolved and my map is rendering properly. Thought I would let you know.

There wasn't any change made in the Map Extractor, so this has been solved by the re-generation of the map
