[ale] Z-Wave or ZigBee

[Alex Carver]

Zigbee is standardized (mostly) and Z-wave is proprietary.  If you want
to expand your system beyond switches (or have a large number of nodes)
go for Zigbee.  You can also buy bare modules for Zigbee that expose
analog, digital and serial I/O so you can make custom interfaces to lots
of dumb hardware.

There is Z-wave library support (closed) for Linux but Zigbee isn't too
difficult to handle raw.

There's modules from Digi that support Zigbee (the Xbee series) and they
also have Xbee modules that support wifi (I currently have three for
various HA tasks).

What I do not like is that X10 has issues in my home and I'm thinking of using RF to directly control the devices. X10 provides me no ACK of a command. I want to be able to query this system to see what state the device is in.

Having done that I then was able to automate it via CLI. I wanted to send commands to the HP system from the 3DS. That device is locked down so I decided to write a web interface that would look like an app. Doing this taught me JQuery, JSON, and a few other technologies that other developers help me out on. After controlling HomePass I decided to control my bench lights (X10). I then added a device that does VHF GMSK to a digital ham radio. Instead of control the device from the radio, I just control it as well from the 3DS,. Eventually the interface will grow and the 3DS will provide me even more info and control.
