<p>Additional thought...the smartthings hub ties into "zwave"
devices which include a bunch of things...including smart light
switches, door locks, etc. Some parts are kind of pricey for what
they are, but the automation is easy to deal with and is kind of
cool from a geek perspective.<br>

<div>Good stuff, however here’s my objectives:</div>
<div>1. The room fan is currently installed and controlled by
a wall switch</div>
<div>2. The pressure pad or motion sensor will be located 15’
away and 5’ </div>
<div>lower elevation (floor level) from the wall switch.</div>
<div>3. I do not want to tear into the walls, so there needs
to be an RF </div>
<div>link between the sensor and the wall switch. </div>
<div>4. The sensor (pressure pad or heat/? sensor) could be
dc (battery) </div>
<div>or could utilize the 110V outlet located 16” from the cat
box entry point.</div>
<div>5. It would be nice to keep the actual wall switch in
operation, but the </div>
<div>new RF switch (with timer) needs to be located at the
wall switch location.</div>

<div>Wouldn't even need the light part. The make a
motion sensor that can replace a wall switch.
Like this one:</div>

<div> </div>
<div>If that doesn't work for you there are stand
alone motion sensors that could be placed near the
cat pan to only detect cats. <br>

<div> </div>
<div>If you are really set on a pressure pad sensor,
I'd probably gin something up with an Arduino and
a Relay. More work in HW/SW development, but the
possibilities are endless. You could log all the
cat box activity, send a text after a set number
of visits to remind you to scoop the litter....
This has a high potential for feature creep...
Gotta run now, off to the shop to start coding....<br>

<div>How about taking a motion sensitive light, and
wiring an outlet/the fan in place of the bulb?</div>
