I have the same issue:

No matter what I do the slider stops at 66%

What settings does the fan have?

[EAuckland]

I have several. Some have three speeds that show on the slider as 33.33333333 and 66.66666666 and won't do high. I also have a could that have six speeds and the slider will only go to 83.33333. when you click on them home assistant will show all speeds and let select all, even high. Seems to only be an issue with the slider.

My fan is an Ikea air purifier with 3 steps and and off state:

Just wanted to touch base on this issue.

Touching base on this as well. I've had this issue for a while and it's always been an annoyance but would love to see it fixed.

There appears to be a rounding error somewhere. I suspect it may affect any fans where the percentage_step has a recurring decimal.

I’ve worked around this by setting max: 100.001. Any values slightly higher than 100 seems to work with no obvious side-effects. I’ve also tried step: 33 and step: 16.5 for my 3 and 6 speed fans respectively. This seems to work fine too.
