The lithium, battery-only design delivers more than 10 years of battery life in normal operation—no wiring or AC power.

With up to 1/4-mile open-air range, the system reaches basements, meter pits, mechanical rooms, and outbuildings where Wi-Fi struggles. Use the YoLink app (with YoLink Hub) for remote control, schedules, alerts, and integrations with Alexa, IFTTT, and Home Assistant. Choose the size that fits your plumbing—1/2", 3/4", 1", or 1-1/4"—and expand within the 80+ device YoLink ecosystem.
