Now that my Frankenstein’s monster is complete, I’m pleased to report that I have successfully cobbled together an Alarm.com enabled mouse trap.
We live in the country, and part of country living often includes mice. We also have pets, so I prefer not to poison the mice - I’d rather trap them. Traditional traps work fine, but our mice like to hang out in places that are not easily accessible (ceiling, crawl space, etc). If I do not check the traps every day I risk creating a decomposing stink bomb. So, it would be nice if the mouse trap would alert me when it catches a mouse - you know, like every other thing in my house that is monitored by Alarm.com.
So I set out to make an Alarm.com enabled mouse trap. This is based on a Rat Zapper electronic mouse trap. I like this trap for two reasons: easy clean up (just dump the little buggers in the trash) and it has a plug for a wired alert when the trap is active. The alert they sell is called a Rat Tale, and is essentially a pair of LED lights on a 12 foot cord - so you can see if the trap has been activated in a slightly more convenient location. I got that Rat Tale too, and liked it - but it still had the basic problem that you had to remember to go around a look to see if the trap had been tripped.
The notification port uses a standard 2.5mm audio plug. I used an old 2.5mm cord I had lying around, but if you don’t have one something like this would work. When the trap is active, it simply closes the circuit on the plug - so I needed a “normally open” sensor.
Ryan let me know about the Honeywell 5817, with the key feature of being configurable to have a normally open loop. After getting this, the rest was easy - attach the wire to loop 1, put the dip switch to be normally open, add to 2GIG panel (using the equipment code for the 5816 worked fine), and configure to notify in Alarm.com. The Go!Control’s vocabulary is limited, so when the trap is activated the panel proudly proclaims “INTRUSION TERMINATED.”
