I would like to lead my existing home installations to openhab.
Mainly, I have an analog control panel at home, comprising about 4 shutters for blinds, 4 traditional switches and a DALI controller for dimmable LED spots.
The architecture I envisage is as follows:
- An Arduino controls switches for blinds and mimics the DALI protocol.
- An old android phone serves as a terminal for the android, which should be connected by USB and communicate by some sort of serial protocol. I find it important that the system Android phone/Arduino is 100% stand alone. Not relying on any wireless connection or other running servers.
- The phone can then use Wifi (or bluetooth, if wifi is not available) to talk to the openhab server
You can find a schematics of the setup here:
Questions: Is there an intelligent convention for the serial communication between the Arduino and the phone, or should I just make something up?
Second thing thats bothering me: Is there a way I do not need to create a GUI for the app handling the communication? Is there something existing or can the existing apps be used?
