Automatic doorbell

[kcshipley]

I live in an earth house, with no windows downstairs except for the "front door" in the back yard

 

So there is no view of visitors coming in from the driveway out front. So I bought 4 X-10 motion sensors, for the driveway, the sidewalk, the patio and just above the "front door".

 

The program below doesn't have a "visitors4?" for the front door yet - I haven't installed that, facing straight down. With just the other 3 sensors, I occasionally get misfires when schoolkids cut through the back yard on their way to the bus stop, or the lawn care guy drives the lawnmower through, or the neighbor short-cuts to the cul-de-sac mailbox.

 

An 8-button KPL in a tabletop enclosure, linked to the X-10 motion sensors has been really nice for "seeing" what's going on outside.

 

The "Visitors buttons group" is a scene with KPL buttons (responders - indicators) all over the house, that flash when a visitor arrives, then stays on for a few minutes.

 

In the Home Theater with the 8 speakers blasting, I originally had a "blink the ceiling lights" program, augmenting the X-10 chime. I might put that back in eventually...

 

Notice that this is what Electrical Engineers call a "State Machine", where specified things must happen in the proper sequence (and in this case, within a certain timeframe) in order to get to the final "state", which rings the doorbell.

 

This (uh...) filters out such occurrences as large dogs and neighborhood kids scampering about, every-which way near the motion sensors, and visitors LEAVING.
