    Works Great Review by Scott
    Works Great

    These work as advertised. A week after I installed on in my laundy room, I received an alert. I had a leaking hot water connector. This save me a disaster as my laundry is on the second floor.

    Saved the day! Review by Edgarvb6
    Saved the day!

    Well, I just finished installing a new water softener in the house. During the installation as you know, the water needs to be turned off. Well I did that, forgetting that the HVAC humidifier (located in the attic) was still active. Long story short, on startup the system fills up and traps air, our city water pressure is 75psi. You do the math, at around 2:30am the night after the softener was installed, the compression tubing for the humidifier popped off the fitting and started to leak. Remember, the humidifier feed the system in the attic. With the water pressure, the tubing was pushed back into the house and started leaking freely in the laundry room. Guess what, that's where the Insteon leak sensor was placed. This little unit saved the day!!! I realized that we had a leak when I tried to brush my teeth this morning with no water. I interface this unit with my home automation PLC and with this combination, when there's a leak Insteon shuts the valve and my home PLC turns off the hot water heaters, softener, and humidifier.

    This is a no brainer, I have three installed and I need three more...

    Thanks Insteon!

    Works well for me; wish it provided battery status Review by Luke
    Works well for me; wish it provided battery status

    Overall, I like these. Here are some thoughts:

    The device includes a battery that is supposed to last ten years

    The device doesn't seem to report battery status

    Other thoughts:
    I originally had the hub at the corner of the second story of my house. The sensors struggled to communicate with the hub until I moved it to the second floor. They now communicate reliably.

    Best product ever! Review by JamesBond
    Best product ever!

    This product saved tons of headache, expense, and awkward explanations for a person house-sitting for us while we were on vacation. We received an alert that there was a leak in the guest bathroom, and it turned out to be a miss-used shower-curtain. A few weeks of water soaking into the base boards and drywall daily would have been a mess, and probably not caught until after there was mold in the walls. Luckily a quick call and short conversation cleared it up, and no damage.
    Awesome product, great system. We love our INSTEON setup and have expanded to other products throughout the house; lights, thermostat, door sensors, motion sensors, over 50 devices and counting...

    Review of 2852-222

    Very slick! Compact, simple, links quickly to my ISY-99i, simple to add to ISY programs to control my Smarthome Select Electronic Water Shutoff Valve. Responds instantly to water on the electrical contacts on the base, sends signal immediately through my home's Insteon network and changes state in the ISY. Shutoff valve actuates within one second of water hitting the contacts. Very impressed, will likely pick up a few more of these for my other bathrooms and basement.

    Review of 2852-222

    This is a quick and easy device for my home. I also have the AQUO from, which has email alerts that I got because I travel a lot. This way, I and maintenance folks can get alerts even If I am away. Wish they had that feature on this one. :

    Review of 2852-222

    Inconsistent functionality in these things. I have 8 of these things and at least half of them don't trigger a Wet Detected broadcast which is required to activate an event. Direct linking works fine but I want an alert when there is a leak!

    Review of 2852-222

    Bought six of these to put throughout the house after a neighbor suffered over $100K in losses due to a busted pipe in his upstairs. Next step is to fully automate and put in the main water shutoff valve to automatically control via these sensors. For now, they text me when there is a problem.

    Review of 2852-222

    Very disappointed. Spent money on product based on description. Now, I find out that I need additional equipment for it to work as intended or I can lose the shipping $$$ both ways to return it. Lesson learned. I'll cut my losses.

    Review of 2852-222

    I would like to comment on the 10 year battery life advertised. I bought 6 of these at the same time and all of the batteries lasted approximately 15 months. All of the 6 units indicated low battery within about a 24 hour period of each other.
