Feature request: setpercentage (+optional timer) after HA update

[golles]

In the latest release of HA (Home Assistant) they moved fan speeds out in favor of a percentage, see https://www.home-assistant.io/blog/#fan-speeds-100

I would like to ask for a new feature, an API endpoint that can use this, including an optional timer parameter:

---

/api/v2/fan/setpercentage.json

Set the fan speed by a percentage of your fan device.

Example:

http://192.168.x.y/api/v2/fan/setpercentage.json?percentage=50

Parameter	Required	Description
percentage	Yes	Fan speed percentage: a number between 0 and 100
timer	No	Set the fan timer (number of minutes)

I just realize this isn't really required as the speeds can be used as preset_mode and the percentage can be set via the voltage.

Up to you if you feel this is a nice to have, else I'm fine you close this ticket
