Double check your vacuum model. I transformed my vacuum into a neat (well, not really) pile of parts in about an hour only to find mine isn't supported. Apparently S7 MaxV Ultra is a completely different PCB and SoC than the supported S7 variants (S7/S7 Pro Ultra). At least I cleaned it while disassembling, so it wasn't a total loss :)

I briefly considered connecting an ESPHome module to the 'start' button so that I could at least start cleaning from Home Assistant, but since it still won't give me errors if there are any, that seems like a half assed thing to do..
