It's mainly for HA. I'm planning on setting something up like if windows are open then A/C off unless it's super hot then A/C on. I do plan on adding something like if windows open after 2am then send email/text and flash master lights or something. I was hoping for a cheap ($100) way to wireup windows since a security system isn't really needed in my area.
x10 ds10a is $20
Insteon Triggerlinc is $35
standard window sensors are like $2
insteon I/O Linc $45
I'm thinking the easiest/cheapest route would be to buy standard window sensors and connect the whole 2nd floor to one I/O linc then connect the whole 1st floor to another I/O linc. Will this work? I figure I could wire the windows all together, I won't be able to see which window is open but atleast will know that A window is open.
