Just a PSA for Home Connect users - if you need to use their support page, don’t mention that you’re a Home Assisant user, or you’ll just get “We do not support Home Assistant … contact them”.
Sure I was trying to diagnose why HA won’t work for me, but I’m getting errors with their online API portal, so it has nothing to do with HA. A GET on “/homeappliances” works but one to “/homeappliances/{haId}/status” produces “HomeAppliance is offline”. This is despite it showing up fine in the Home Connect app at the same time.
