There currently is a way to define binary sensors in the GUI using a template helper. However, it always involves Jinja2, which is hard for new users.
We have a way to write a compound condition resulting in a true/false using a GUI editor, namely in the condition block of the automation editor. You can use and/or, state and numerical state conditions to write complex, compound conditions in a way that is familiar to starting users.
So I think it would be great to add a binary sensor helper that uses the condition part of the automation editor to define the binary sensor.
