Mostly into weather here. I have the following direct serial/USB connections to the "motherships"
1 - CM11A - X10 - X10 lighting control
2 - Maxim 9097S X 3 (1-wire sensors)
3 - Midon Temp05 and two Midon Temp08's connected to 1-wire sensors
4 - Insteon PLM - Insteon Lighting control
5 - AB8SS - serial 8 speaker pair switcher
6 - NetcallerID boxes (2) - Caller ID to serial boxes on two phone lines
7 - WGL W800 (X2)- wireless X10 stuff - serially connected
8 - RFID receivers (3X) serially connected
9 - Way to Call device (X1) - phone line / call center management box (kind of overkill for one phone line).
10 - UPB serially connected controller (lighting control)
11 - HAI OmniPro II panel (autonomous with a serial connection)
12 - Russound CAS44 - serial on and off 4 zone 4 source audio amplifier with serial / Keypad control
13 - Leviton Z-Wave controller
Something like 800 variables (which always change) and about 200 events / scripts running on the "mothership" and another ~ 50 events running on the alarm panel. So the touch screens can show any of the variables or run any of the events.
The mothership today controls the Jogglers displays (dim, bright, screensaver or what screen is displayed or just shutting them off remotely).
Outside motion is using PIR's, Geophones and video. Geophones are neat little devices used for mine detection / very sensitive to even footsteps on grass/cement or asphalt. Also utilize conventional "driveway" sensors - "motion tubes" buried on both sides of the driveway.
Two of the vehicles have CarPC's and can tether their connection to the internet running the above screens such that you can remote your home via the automobiles or your cell phone if you choose.
You can get into the world of Home Automation with the Joggler by using a "free" flash based front end with connects to another piece of software which is also free utilizing XAP. Adding a couple of devices on your network like arduinos you can be into the world of home automation for less than say $100 USD. This is similiar to your post above. The Joggler could be the heart or the mothership of your home automation.
