reolink_dev.ptz_control: Speed parameter

[diamant-x]

Hi,

Thanks for this integration. I was looking for an enhanced ONVIF integration that would allow me to control FocusIn and FocusOut.
While it would be awesome to have a specific Service call to set Focus (and zoom for that matter) to a specific degree (for example from 0% to 100% based on the camera capabilities, just like Reolink's native controls offer), I'm trying to setup a script to increase/decrease a specific amount the focus. I know i need to do a STOP call after the FOCUSINC call to stop it, however i'm having issues controlling how much time to leave between the first FOCUSINC call and the STOP.

• What are the values for speed parameter stand for?
• How should it be correlated the amount of time between the action and the Stop, to the actual action?

I saw it accepts any positive integer value, but i'm not clear how to define it. My gut felling tells me it might be the amount of milliseconds that the camera should take to do such action from current position to maximum position, but i'm not sure that fits the behaviour I'm seeing.
Any help would be greatly appreciated.
Thanks!

PD: I'm using a E1 Zoom, if that's relevant.
