Thanks you SO much for posting this and BIG thanks to JDRoberts and jkp for such complete and concise solution descriptions. I’m pretty sure if I hadn’t been sleeping with one eye open, I would’ve been smothered with a pillow last night.
The same exact thing happened with the hose bursting under the bathroom sink. We also had a flood similar to what you mentioned several years ago where a toilet tank leaked upstairs while we were away for the weekend. So I’d bought audible alarm type sensors then and replaced in stages with these ST sensors.
So my family isn’t as into ST as I am and giving me a hard time because the sensor didn’t trigger. Everyone kept using air quotes with SmartThings and laughing. The sensor works but my placement was poor because of some slope apparently. Where I had the sensor in the water closet was higher and therefore dry at the point of discovery. This bathroom is large and now I see the need for an additional sensor near the sinks. If it had run for just a little while more it would’ve hit that sensor but glad it didn’t as there is hardwood flooring on the other side of that wall. Just want to include this info so others may potentially benefit. More is better with water sensors and check for slope with placement.
Even though I knew the sensor didn’t fail, I wanted to test and show my family it works…near midnight when we’d finished cleaning all the water up in the bathroom, master closet and my office where it ran into due to the slope. In hindsight I should’ve waited until this morning if I even hoped to swing anyone over to Team ST.
The Home Monitor notifications went off hourly until I found this thread this morning. We cannot put our phones on dnd because we are on call at night. Lessons learned. More sensors on the way. Ironically we were going to put in a shut off valve z wave controller but realized Saturday the valve is stuck, corroded or whatever…won’t shutoff and needs to be replaced first. Thankfully I had a key to shut it off at the street.
