service: fan.set_speed not working for sending 'low'

[quadhammer]

I was having trouble designing a card for various speeds, but I think it may be something a bit lower level. When I use the developer page to send a speed of low, it's showing up as medium. I can send medium and high to change things, but just not low.

Here's a picture of the issue, in case am doing something wrong: https://imgur.com/a/ZFvcPWH

set_speed is deprecated in Home Assistant.

Check for the percentage_step in the attributes to determine the speed steps and call set_percentage instead
