### What issue do you have? Please be as thorough and explicit as possible.
The new fan speed configuration is not working properly for me. It shows as a 0-100% scale and I have to select by moving the slider a pixel up or down. My fan is broken in all automations, which wouldn't be a huge deal to fix except that the fan in all automations is still shown with the original 0%-33%-66%-99% setup, so I can only set it to off (0%) or full speed, since obviously 33% is above 3%. This persists even when I remove and re-add the accessory to the automations.
Attached is a photo of what my UI looks like.
