possible upgrade 9) window rolling shutter about esp-homekit-devices HOT 6 CLOSED

Is neccesary a sensor to control current position. This is an advandced version of a garage door. Advanced because a garage door doesn’t keep middle open, but a shutter yes. I am going to develop garage door first, and shutters will be after in a future.

Many thanks for your suggestion.

Recently I have created a board to control my rolling shutters remote control and used homebridge to integrate it into homekit and see it as a shutter accessory there.

My experience says that it is much easier to achieve the control part but quite tricky to achieve the reporting of current position. This is because current position of the shutters could be changed when the shutters can be controlled from a source outside of this system (i.e. RF remote control or wall switch) hence home app will not be in sync anymore with real position.

It's a very interesting enhancement though.

@peros550
The external source veins connected to the botton1 for the ascent and to the botton 2 for the descent so the position will always be consistent, with that of the app.

@RavenSystem
Surely with an incremental encoder the position would be perfect.
But I already use a system of this type and it works very well, calculating perfectly the rise time and the time of descent are able to always have the position of the rolling shutter.

This will be possible when saved states is implemented, because position must be saved to flash to avoid problem with reboots and initial shutter position.
