Hi @Guillermo-Schimmel , right now I'm just trying to do what you did. I'm interested in building a home automation system based on openhab and a raspberry pi from scratch, which reliably controls the roller shutters at home. I have already built one in the past, very basic, which using some relays turns on and off the lights and allow to simulate the pressure of the buttons at home raising and lowering the blinds. However it lacks to indicate their real position, and moreover, by pressing physical buttons at home, their new state (fully up or down) can not be communicated to openhab, so I can't know if they are really up or down. So I decided to start from scratch building also a new control unit for the shutters. The hardware of this project is extremely interesting, but I can not figure out how to interface it with openhab.
My idea would therefore be to build two control units, a primary - which I will use for the lights and other sensors, very similar to the one I already built and use - and a second one dedicated to the shutters, based on this project but with the possibility to manage five shutters and connected to the first with serial or rs485 (they would be very close, so I would avoid the radio section with attached authentication). Can you help me, giving me information about the connection between this project and openhab, so I can succeed in this little adventure?
