YoLink EVO Valve Operator Automatic Water Leak Detection & Shut-Off Starter Kit: Reliable device-to-device communication during power loss or network disruption
For homeowners who worry about hidden leaks in basements or behind appliances, this YoLink kit is your proactive shield against water damage. It starts with peace of mind, not just security, by automatically shutting off your water when a sensor detects moisture, so you can focus on your day without constant checking.
The system uses reliable LoRa technology to cover your entire home, even in remote spots like attics. I placed a sensor under my washing machine, and when a small drip started, the valve closed before my phone buzzed with the alert. You get customizable notifications via app, email, or SMS, plus integration with Alexa for voice control. With up to 5-year battery life on sensors and easy, tool-free installation, it protects your home seamlessly.
