Door Bell detection
« on: September 24, 2004, 03:46:50 PM »

I cannot believe that I am the only X-10
user who would like to detect door bell
presses.  Does X-10 plan to eventually offer
one?  Is there some way to rig a 16 Volt
current-decting device to do this?

You should be able to do door bell detection
using a Powerflash module (model PF284). It
takes a low voltage input, and sends an X10
On or Off signal based on the change in input.

Yep - I've used one of those and
a 'waterbug' to let me know when I had water
in my basement.  It works very well.

The PF284 can detect the voltage if it is
connected across the bell. Another way is a
small board that Smarthome has. It connects
in series with one leg of the transformer
and detects the current when the bell is
ringing. It too connects to the PF284 acting
as a switch closure. The thing is actually
three of the modules on one board scored so
it can be broken into three. One has
components that where picked to detect a
phone rinning signal and the other two
current like from the bell transformer.
