I have a zhimi.fan.sa1 smart fan and the HA integration using Xiaomi Miio works very well but it lacks any control on the angle of oscillation while Xiaomi Home App allows control on angle of oscillation for 30, 60, 90 and 120 degrees.
Sorry, it actually has the control on the angle of oscillation. It is listed under configuration.
It would be nice if the Oscillation angle can be put under “Controls” instead of under “Configuration”.
