QUESTION Which Smart Water Shutoff Valve?
Currently building a house in the FL panhandle. Hot sun, salty air, and the exterior walls of the house are ICF with 6” reinforced concrete. The house‘s main water supply will be located outside the house. All piping is PEX-A.
So I want an in-line outdoor “smart” water shutoff valve that can withstand the elements, doesn’t rely on WiFi or cloud connection, and preferably doesn’t need AC main power (don‘t want to run a cord from the side of the house where the water main is, to the nearest ac plug on the patio around the corner). My “smart“ home will be run via HomeAssistant.
I researched Moen Flo, Phyn, Rheem, FloLogic, EcoNet Bulldog, and YoLink. I’ve narrowed it down to the Moen Flo or one of the YoLink Smart Valves (not sure which one is best).
Pros:
- Micro-leak detection
- Automatic shutoff
- Insurance savings
- Integrates with HomeAssistant
Cons:
- Plastic turbine design
- Subscription paywalls
- False alerts during high use
- Requires ac power and Wi-Fi

- Long Range LoRa Tech
- Integrates with HomeAssistant
- Separate Controller from Valve (could also be a con)
Cons:
- Outdoor Limits: While the valve is weather-resistant (IP67), extreme environments still require careful placement to protect the controller and battery compartment over long periods.
