Hi guys.
Does anybody tried some of these protocols for home automation? I have read a lot of comparisons and don't know what way to go.
I'm not good in HW development therefore I will not build my own devices. My plans are build existing devices, control them through some USB controller connected to my Linux home server.
We've bought few zigbee boards, they should have fairly large range. I don't know about the Z-wave protocol.
The zigbee boards' main problem was that they required some proprietary windows utility to program them, which acutally does it via UART, so it's fairly simple to sniff the commands. They may be already (unofficially) documented somewhere.
Second problem was that the ones we got a fairly high failure rate (I think 2-3 out of 5 simply refused to be programmed). Not sure if it was just bad luck. Maybe I could find them somewhere and bring it to brm for testing.
Some vendors sell devices with a proprietary sw layer on top of zigbee. Such devices might not work with others.
Z-wave products *should* work flawlessly as any product marked as z-wave compatible has to be certified by z-wave alliance. There is a shield board for raspi, called RaZberry, this is what I'm planning to start with.
