Moen Flo water shutoff

I’ve got Moen Flo and on several occasions my toilet chain got tangled on itself, holding the flapper up after a middle of the night flush, and it detected it and shut the water off. Integrates fine into HA and I have YoLink sensors around the house that will also detect a leak and trigger a HA automation and use the Flo to shut the water off.

Great summary! Detection v. mitigation is key - that's why I ultimately went with the Moen Flo as it can (and will) intervene if it thinks something looks anomalous. I also like the fact that it does nightly "leak checks" by shutting off your valve for a second in the midle of the night and then looking for pressure drop-off..

I have a Moen Flo that has been pretty reliable. Only thing I don’t like is that it doesn’t tell you where the issue is. I had a toilet that ran and the Flo shut off the water. It took some time to figure it out. I also have the Aqara valve with several sensors around the house (behind washer, under dishwasher and behind toilets. So far it’s been pretty reliable.

Moen has worked great for me. Caught multiple leaky toilets. After the first few months the false alarms have been rare. My main complaints are cloud requirement for HA (never been a problem before but also they just forced a migration to a newer app so we'll see...) And not much control over selecting what appliances you have after the initial setup. It qualified me for home insurance discount. Also if I ever sell the house I think a potential home owner will appreciate a commercially supported product over a diy one

I use the Moen Flo. It can track usage, pressure, temps and of course shut off your water main. It integrates with home assistant and notifies you if it loses connection, drop in pressure, abnormal usage, etc. I got mine of eBay for the cheap.

Moen makes a smart water shut off valve that they call the "Flo," but it's cloud based/proprietary and it's outrageously expensive. I haven't really seen or looked at any others, but I do think these should be a thing. It would be handy to have an automation that turns off the water main if any leak sensors (under appliances, sinks, toilets, etc) go off, but it would have to be a reasonable price. Sure it could save a lot of money *if* there's ever a problem, but I've never had a sudden leak or a pipe burst in any house I've ever lived in. I've had water that's come in from outside (flooded …

The problem The FLO by Moen integration's `sensor. _today_s_water_usage` (`translation_key: daily_consumption`) resets the daily counter at midnight UTC, not at midnight in the user's local timezone. This makes the "Today" reading drop to zero mid-afternoon (5 PM Pacific Daylight Time, 4 PM PST, etc.) and appear suspiciously low for the rest of the evening. The bug persists even when the FLO mobile-app account timezone is set to a non-UTC zone (e.g., `US/Pacific`). The integration appears to relay whatever value the Moen cloud API returns for daily consumption, and Moen's cloud calculates …
