I have a number of HDL-BUS devices installed at my house and I have designed and developed code for additional ones based on the arduino platform. The protocol is open source so its possible to everyone to design compatible devices.
I am now looking for a compatible central automation software to integrate everything in a nice looking dashboard. I ve looked at domoticz and openHab but it seems that neither has builtin support for my system .
Anyone know of any other platforms that either support HDL BUS or its easy to add support by defining the protocol?
Watcher, thank you for the info. No, I do not use Smart Bus devices, just curious about its protocol. I think RS485 is not the best choice for home automation.

If you can have cat5 cables routed all over the house, it works fine and its very reliable.
Its just difficult to retrofit on existing buildings.

I do have cat5 cables routed all over the house, but I refuse to use RS485. I prefer to use CAN transceivers instead.
RS485 is not suitable for CSMA/CA or even for CSMA/CD. RS485 transceivers diminish communication to "master-slave" paradigm. It is not good for home automation. CAN transceivers are suitable for CSMA/CA and for "producer-consumer" paradigm.

True. In my own implementation of the above protocol i have opted for a software version of csma/ca where the bus is sampled before transmission and if busy, transmission is delayed.
