Domos Project

The domos project aims is to provide a global, low cost and open source solution for home automation.
A first proposition can be found here: [1]
Three developpers are actually registered.

Subprojects:

• Endpoint / controller communication (LS_Link)
• Controller/controller/server communication (HS_Link)

1. LS_Link

A zigbee solution is foreseen for the wireless communication.
This has to be evaluated.
In order to be able to benefit from the complete Zigbee services, two Microchip ICs will be used (PIC18Fxx and the MRF) as the Zigbee stack is provided for free [2].
Next steps:

• 2 zigbee prototype board with a PIC and the MRF. One will be used for the endpoint and the other will be connected to the APF through the RS232 (TTL) interface.
• Specification of the communication protocol between the APF and the endpoint (datagram based ?). Evalution of the actual solutions.
• Developpment of a small application on the APF side to communicate with the zigbee board by using the communication protocol previously defined.
• test of the Zigbee stack provided by Microchip. A simple programm has to be written. Default Microchip environment has to be used.
