Utilizing this integration to auto-set the profile of a z12e for night/day. My headache is that the focus for the two sensors is just slightly off. It looks like bp2008's service was running a method utilizing http:///cgi-bin/devVideoInput.cgi?action=adjustFocus&focus={}&zoom={} and was hoping you might be able to add this method as a service to the integration. I tried finding the api documentation for this action but wasn't able to find it in the Dahua IPC HTTP API.

Thank you though for this integration, made my life a lot easier than having to run a windows service.

Agree with above commenter. Need to see if able to zoom in or zoom out like BP's service :)

My experience with github isn't the greatest so I won't try and do a pull request (as well as this is my first time toying around with python, so I bet there are better ways to do what I did other than just frankensteining your current work)

I created an adjust focus method that utilizes the above api. You would need to pull your current zoom/focus from your camera to utilize in your service calls. You could also incorporate a call to "/cgi-bin/devVideoInput.cgi?action=getFocusStatus" to get those current values as well.

One headache that would need to be taken into account is that you have to call the method a couple times over a few seconds each attempt. It appears that when you first call it tries to adjust the zoom and focus at the same time which it doesn't like, so each successive call gets the zoom into the right position then gets the focus in the right location

Hope you consider it worth adding into the integration :)

Oh also, the items added Camera.py: SERVICE_SET_FOCUS_ZOOM = "set_focus_zoom"

            vol.Required("zoom", default=""): str,
        },

    )
