Setting fan speed from homekit automation results in incorrect speed

[rcork]

The problem

I am using the BAF integration and exposing the fans to Homekit. When i include the fan in a Homekit automation, whether its a Scene or the action for one of my homekit buttons, i've noticed the fan speed being set incorrectly. For example, if create a scene that sets my fan to 85% and then trigger the scene, the fan will turn on and set the speed to 85%, but then immediately set the speed to something lower like 57%. However if i just control the fan manually from the iOS home app and set the speed to 100%, it works correctly.

When i look in the logbook after triggering the scene, i see two entries one right after the other. First is the command to set the speed to 85% followed right after by the turn_on command. I think whats happening is the turn_on command is setting the fan to some default speed, overwriting the percentage set in the previous command. Here's the messages from the log book in ascending order by time (latest event on top)

Homekit send command turn_on for Master Bedroom HomeKit send command set_percentage to 85.71428571428572 for Master Bedroom

I've tried the homebridge baf i6 plugin and it doens't have the same issue with homekit scenes or automations but prefer HA's integration as its more feature rich and flexible

Hey there @bdraco, @jfroy, mind taking a look at this issue as it has been labeled with an integration (baf) you are listed as a code owner for? Thanks!

Code owner commands

Thanks for the report. I'll try to look into this next week. Maybe @bdraco will chime in as well.

I can't get this to happen.

Probably going to need debug logs for homeassistant.core to see what service calls are being made

I enabled debug logging on HomeKit Bridge and BAF and captured the homekit automation trigger event. Does this help? At the end of the log it looks like it sets the speed to 85% but then receives a request to set preset to auto and speed to 57%.
