YoLinkSmart Water Depth Sensor, Liquid Level Sensor, 32ft, Long-Range LoRa, Real-Time Alerts, Automation, Battery Up to 10 Years, Liquid Density Adjustable, Hub Required, YS7905

This is a fantastic device, which I use to monitor the water level in the pit for an outdoor sump pump,. Very easy to install and configure. For the last three weeks that I have used it, it has functioned reliably and accurately with no issues with the ground water which contains some soil sediment. Note that the minimum interval for measuring is 10 minutes. During very heavy rains, the pit can fill within a minute, but I have the YoLink water level sensor to cover that. The YoLink products are fantastic. I have many smart home devices from Wyze, Arlo, Amazon, and Google, and YoLink holds its own in terms of unique set of capabilities and the great connection range of their hub (far beyond WiFi). The other companies do not offer the functionality that I could only get with YoLink/YoSmart products. Their products do not require WiFi. I was concerned about requiring a hub, but the hubs remove the need for WiFi and provide amazing coverage of my house and property. I have the SpeakerHub and the 4G/LTE hub which will send data and notifications even if our Internet goes down. Their devices are very easy to set up and the hubs are very small. I have 11 of their products and will likely get more. Customer service has been terrific--professional, knowledgable, and responsive.

Love this. Put on a waterfall sump that’s concealed. It’s very handy.

We have a 4000 sq ft home with 4BR and 4 baths. Our well system was not able to deliver enough GPM for both the home and irrigation system. So we installed a 2500 gallon fresh water tank along with all the other needed check valves, float switches and 3HP 3 phase pump with VFD control. We purchased three Yolink powered valves to control water flow along with their pressure depth sensor and hub. It's easy to see the hard work that went into creating these products. Install was super simple and worked the first time. In the future we may add water sensors to the home. But for now just enjoying the automation at our well pumps.

This was very easy to add to my monitoring system and the wifi range is excellent. The monitoring interval can be set between 10-60 minutes. I set it at 30 minutes. I'm guessing that shortening the time to 10 min would reduce the battery life.I'm uncertain about how the alert interval relates to the monitoring interval. i.e., if the monitor interval is 30 min and the alert interval is 5 min, will I get an alert promptly or will it be delayed by 30 min.Overall, I'm very pleased I bought this monitor. It's expensive but it is working as it should and seems to be well made and very durable.

I installed this in my 5000 water tank that is 800' away up a hill from my home. Easy installation. Easy to calibrate for the size of the tank. Appears to be pretty accurate so far in use. I have been very satisfied with my YoLink products.

We test and deploy many Yolink devices and this is sure to be one of our favorite devices. We provide commercial monitoring for Hatchery ponds, and this will greatly simplify installations, plus add reliability, to a critical industry; not to mention lower costs significantly.
