Trusted redundancy
Great system at a reasonable price. Under $300 for the entire system of sensors and valve now protects my home with confidence. Backup redundancy leaves is confident that water damage will be mitigated even if the internet or power is down. Easy to install and good app. Protected all sinks, toilets, washing machine, refrigerators, dishwasher, and sump pump with appropriate sensors for a value that competitors were unable to meet at a larger cost with less benefits. (Note: a simple leaking refrigeration icemaker line resulted in over $2000 in damage in the past)

It will not work without internet
I bought YoLink LoRa Smart Water Leak Protection System, Including Smart Motorized Stainless Steel Valve, 3 Water Leak Sensors and Hub. I paired all devices with Hub. When Hub online with internet all leak sensor work great when its detect water leak and the smart valve close . But without internet leak sensor detect water the smart valve does not close. This system useless without the internet.
