Doing a lot of reading on home automation lately and I am surprised to see that Z-wave is the protocol that HG is supporting. It seems like Zigbee is more open. For example there are Zigbee shields for Arduino, but no Z-wave that I can find. SmartThings is using Zigbee.
I bought the GE Wink hub which supports both because of a deal at local HomeDepot store (buy 2 compatible products get the Wink hub for $1... but then I found out the compatible bulbs also need there own gateway (yet another protocol), and another $66. I am planning to take Wink hub back and wait for for the "protocol wars" to settle out. So I dug my old X10 gear out of the basement and found HG to get me by so I don't waste money on the losing protocol.
in HG, why is Z-wave being used and not Zigbee? Is Zigbee support being added? Are there still multiple Zigbee variations that cause difficulties? I haven't been able to determine that but my impression is that Z-wave is less open and more expensive to to licensing.
Anyway... just wondering what the future will be in Home Automation with so many devices/hubs popping up past year (Lowes Iris, Staples Connect, SmartThings, GE Wink, etc).
Thanks!
