Re: TriggerLinc Button 1 & Applescript

Cheap ($19) and effective. It's really just pair of contacts that when water touches both, the current flows through the water from one contact to another. About as simple as you can get, but very effective as it can be used over and over again. While being simple, it also is very dumb. For $19 it doesn't check humidity levels, or get fancy in any way, but I wasn't looking for that. Think "KISS" principal...
I like the solution so much I am thinking of buying a few more, some of the rest of the toilets in the house, some for the water heater and A/C units, and one for under the kitchen sink. Since I like in a vertical (townhouse) house, a water leak on one floor will run to others, and the cost of overflowing bathtub can easily run +$1k in repairs.How I built It
I needed to monitor for a toilet overflowing, so I bought a TriggerLinc, popped the case off, and connected this sensor the the screw down terminals inside the TriggerLinc (only two wires to connect - easy). Then, after snapping back on the TriggerLinc case, I put some strong sticky tape on the TriggerLinc and stuck it to the back of the toilet tank, out of site. Then, I ran the included wire to the sensor from the TriggerLinc down to the floor (only a few feet), and used more sticky tape attach the sensor to the wall board where it meets the floor. Since the sensor is on the floor, or really by design, about 1/16" above the floor, it can detect if there is water behind the toilet. If I was clever, I would have mounted the sensor into the wall with screws, but it was a tight area, and I was lazy Indigo Configuration
With the jumper inside the TriggerLinc "jumped" (thanks again Jay!), I have a Trigger for Sensor #2 ON, (water detected) and a Sensor #1 ON (water not detected). These Triggers set a variable (isWaterOnBathroomFloor = TRUE) to the state (I could just check the TriggerLinc state, but I like variables), and have it turn on all the lights in the effected area (why fumble for a light switch when you are standing in water!). It also sends me an email and SMS as well as "speaking" about the water leak via Indigo.Why I like it
4. Runs on a single AA battery. No need to "plug it in" means less wires.
5. Easy to test - just spill a little water on the floor and in 1-2 seconds Indigo registers it.Potential Problems
1. The battery in the TriggerLinc will need to be changed when it runs out (no idea when - 6 months maybe?), and being behind the toilet, it's awkward to change.
2. If someone splashes a lot of water around, a puddle the size of a paperclip could set off the TriggerLinc in false-positive mode (unlikely, but possible)
3. Looks weird. If you notice a wire running from the back of a toilet, it looks strange. Is it a bomb?
Luckily the wire and sensor are white, and so is the wall/toilet.
Hope all this helps!
