YoLink 1/4 Mile Super Long Range Wireless Leak Sensor LoRa enabled Smart Water Leak Detector Alert Notification App Alerts History Logs Sensor with Sensitive Leak Probes, YoLink Hub Required

YoLink 1/4 Mile Super Long Range Wireless Leak Sensor LoRa enabled Smart Water Leak Detector Alert Notification App Alerts History Logs Sensor with Sensitive Leak Probes, YoLink Hub Required

Q: Is there any way to use the water leak sensor without buying an hub? I have Amazon Echo, would that work?

Sorry, no. YoLink Hub is required to set up YoLink Smart Water Leak Sensor. You can order YoLink Smart Hub from the link https://www.amazon.com/dp/B07TQLKQLJ or you can order our Smart Home Security Start kit which includes this Smart Leak Sensor, Link: https://www.amazon.com/dp/B07V246GCX

Q: Is there an audible water leak alarm without using the app? Onboard alarm?

1. For the waterproof function of the product, we do not have a sound function for YoLink Smart Water Leak Sensor; 2. We will release a YoLink Siren soon which can connect multiple YoLink water leak sensors and other YoLink safety devices, with long distance coverage and alarm even without network connection; 3. Because of the long coverage distance of YoLink products, even if there is sound in the sensors, we still can't hear it, Alerting user's Smart Phone is more important. What's more, our YoLink Siren is even more comprehensive. 4. Reduce its own sound function, which can be waterproof and lower power consumption. The battery life of YoLink Water Leak Sensor can last for more than 5 years.

Q: can I use to turned a switched off if it detects a tank reached a level of water?

You will need a yolink outlet or a yolink wifi togle switch ( depending on the device you are wanting it to turn off ) to link the water sensor together. Then set an "if" scenario and you should be good to go.

Q: why is there such a stark difference in battery life between water sensor 1 vs 2? version 1 is up to 5 years while version 2 only up to 2 years

Water Leak Sensor 2 has a sounder. You can optionally turn off the sounder, but since that draws current from the batteries, it is factored into the battery calculations we used. We tend to lean towards the more worse-case scenario (more frequent use, with sounder enabled) but your experience with it will vary and it could very well be closer to 4 years than 2.
