Michael's Home Instrumentation

• New porch doors have required me to rethink my doorbell!
• We can't hear people knocking on the door
• The people at the door don't know if the old doorbell actually rang
• The old wireless doorbell often didn't ring because the batteries were flat!
• The wireless doorbell didn't require drilling holes in the doorframe - this is a plus
• the 12V battery in the wireless doorbell pushbutton was expensive!

I want to do something simple with the old wireless doorbell and start to develop an extensible home automation/instrumentation project. I have a Nanode and a number of Xinos which I intend to connect on a 4-wire bus around the house.
