| | *[[Domozig Project]] |
| The domos project aims is to provide a global, low cost and open source solution for home automation.<br>
| | *[[Domoticz]] |
| A first proposition can be found here: [http://www.armadeus.com/downloads/assos/domos.pdf]<br>
| | *[[Node-RED]] |
| Three developpers are actually registered.
| |
| | |
| Subprojects:
| |
| * Endpoint / controller communication (LS_Link) | |
| * Controller/controller/server communication (HS_Link) | |
| | |
| ==1. LS_Link==
| |
| ===Zigbee===
| |
| A zigbee solution is foreseen for the wireless communication.<br>
| |
| A presentation concerning Zigbee can be found here: [http://www.armadeus.com/downloads/assos/zigbee_slides.pdf].<br>
| |
| This has to be evaluated.<br>
| |
| 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 [http://www.armadeus.com/downloads/assos/domos_zigbee_stack.pdf].<br>
| |
| | |
| MRF24J40 Transceiver [http://ww1.microchip.com/downloads/en/DeviceDoc/39776a.pdf]<br>
| |
| | |
| <strong>Next steps:</strong>
| |
| * 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.
| |
| | |
| ===RS485===
| |
| Wirelless communication is the best way to connect Endpoints and controler. But sometimes wired connexion will be need for direct or faster access. We could considerate RS485 connexion.
| |
| With RS485 nom we can connect up to 32 controllers on one bus.
| |
|
| |
|
| <strong>Next steps:</strong>
| | ==Links== |
| * APF with RS485 transceiver with a PIC and the same transceiver.
| | * [http://www.linuxha.com/ Linux Home Automation website] |
| * Needs to connect APF to a RS485 bus : Linux driver developement? UART driver ? | | * http://www.zorg.org/homeauto/index.php |
| * Schematics for connecting a pic to RS485 bus
| |
| * Specification of the communication protocol between APF and endpoint. Application protocol can be share with Zigbee high level protocol or, must we developped new protocol ?
| |
| * Developpment of a small application on the APF and on the PIC to test communication.
