I am just getting going with Home Assistant and starting to get the basics in - plugs, light switches etc using z-wave.
I have some PowerView blinds which integrate nicely with HA and I have been playing around with various automations that make them open / close. Since the blinds sit above a window sill that sometimes will have glasses or other things in the way, one thing I would like to do is add a condition that checks if there is some sort of object in the way. The bit I am stuck on is whether there are any devices that could do this that integrate with HA? For example, if there are devices that could measure distance, I can place one on the window sill and assume that if the distance is less than X, then something must be in the way.
Has anyone else got something like this working? What would be the correct term for these devices (I have searched for proximity devices but seem to get devices back that focus on how far a person / device is away from something) and do you have any recommendations?
Thanks!
