Sonoff Zigbee Smart Water Valve vs YoLink Smart Sprinkler Timer

Alarm Strategy settings send app push, email and SMS notifications, and can trigger YoLink sirens, SpeakerHubs or a scene. The timer also reports low battery in the app and blinks its LED red when the batteries need replacing.

The user guide states the timer connects to the internet through a YoLink hub and does not connect directly to WiFi or the local network. The radio is LoRa, rated up to 1/4 mile in open air.

The timer can be used as an action in a YoLink automation (for example, start watering when a soil moisture sensor reads low), and Control-D2D pairs it directly to another YoLink device so it keeps working without internet or cloud.

The app keeps 180 days of watering logs, showing when watering started, how long it ran and how much water was used, plus a watering calendar view.

The integrated flow meter measures real-time water flow and total usage, which is what makes gallon-based watering and the usage logs possible.

Alexa supports neither the Matter Water Valve device type nor any irrigation category, so the valve has nothing to map to

The official Home Assistant YoLink integration lists this exact model in its supported devices: YS4103-UC (Sprinkler Timer).

Volume Mode delivers a set amount of water instead of running for a set time, selectable per schedule alongside Duration Mode.

Each schedule lets you pick the watering duration or the watering volume, and the built-in flow meter measures the water actually delivered.

Up to 12 schedules at a time, with start and end dates, repeat days (daily, weekly, odd/even or custom cycles) and start times. Schedules run on the device itself, so no internet connection is required.
