Does it's job and then some so far.
Working good so far. Detector send high temp and high humidity warnings because we placed it in an attic space.

Most reliable
After trying several different water leak detectors, I finally chose to stay with this one for it's reliability. I've had some that fail when I needed it most, and others that gave false alarms. One kept losing connection with the WIFI. The rope sensor is a great invention, as I can lay it out to cover a large area under, say the kitchen sink. It works every time, even with the smallest leak, and believe me, we get plumbing leaks often. My only con is that it takes a while for the detector to send the signal to the app on my device. It could be a disaster if it's a pressure leak. My next project is to place a sensor around the air handler of the air conditioner in the attic. At 20 feet away, a series of rope extensions is a little costly, so I hope an audio extension cable will work, and then I'll route the sensor above the ceiling, and around the drip pan. I was reluctant at first because of the price, but if it saves further damage to cabinetry, and the ceiling, it is worth it.

Should be installed in all houses
Should have been 5 stars but a bit fussy to configure wi-fi. Protecting both under the sink and dishwasher (using extra cord) Very happy with this purchase.

Ordered Honeywell Lyric - got Resideo
Searched for a Honeywell Lyric water leak and freeze detector. Found it on Homedepot.com I thought. Ordered 2. Got something that says Resideo not Honeywell. is it the same device? No way to tell. Seems Honeywell spun off a division and named it Resideo. Still is it the same product just rebranded? I would say false advertising by Home Depot. I think I need to returnm these and ask for what I ordered and was displayed on the web site. Or these should be free. Not happy with Home Depot. I know nothing about Resideo but I do see a lot of issues with this device.

    Saved me from major damage!
    I'm so happy I purchased this sensor. 3 days after installing it, my hot water tank released a whole bunch of water, which flooded my utility room. I would have never known about it because I rarely go downstairs. I received a notification on my phone and the alarm on the sensor alerted me right away. It saved my flooring and walls!

    Works well, but confusing output
    Using as temperature sensor at remote location; not using water leak functionality. Works as advertised. Easy set up. Only confusing part is how to interpret the graph over time of temperature. There are *two* series plotted on the graph, and I expect only *one*: the temperature at the time it’s taken (I have it set to record every 8 hours). Nowhere in the documentation is this explained why there are two curves plotted on the temperature graph.

    Great device every home owner/renter should have
    We've got several of these around the house. A little pricey but they've saved us thousands of dollars by letting us know when water is present.
