Live View Overlay Showing Fans actively running

[BrownDog56]

Hi, Is it possible to be able show that a fan is physically active (motion) rotating, not just having fan status as 'ON' or 'OFF' which is like a light switch being on or off but is the light working. ?
At the moment I have a Infrared Line/Object Presence sensor which is positioned under the fan with one of the blades painted white, a little python script I have to run thoro SSH to show fan is spinning.
But I would like to see this Fan is spinning on the live view overlay. Is it doable. ?

Unfortunately, this is not possible directly in the fan code. It is technically possible using the Image Pre-Save Hook option which is at the bottom of the Processing tab.

The Image Pre-Save Hook can be used to run a script during image processing and it can return JSON data (strings) which can be used in the Image overlay/labels.

This is the template script: https://github.com/aaronwmorris/indi-allsky/blob/main/misc/example_image_presave_hook.py You could integrate your python code into this script and return the custom_# variables which can then be used in the Overlay.
