The manual states the device reaches the internet through a YoLink hub and does not connect directly to Wi-Fi.
Uses the YoLink LoRa protocol, rated up to 1/4 mile in open air. A YoLink hub with an internet connection is required for the app and remote alerts.
Z-Wave 700 series with Z-Wave Long Range (version 2.0 of the ZAC36), S2 Authenticated security and SmartStart. It controls remotely only through a Z-Wave hub, and the wired leak probe works with no hub at all.
Closes automatically when a paired Z-Wave leak sensor reports water, through the hub's automations.
YoLink lists Alexa among the platforms this device works with, set up in the YoLink app under Settings, Third-Party Integrations.
Zooz says Alexa speakers have no Z-Wave radio and reach Z-Wave devices through a compatible hub such as SmartThings or Hubitat.
Zooz says Google speakers have no Z-Wave radio and reach Z-Wave devices through a compatible hub such as SmartThings or Hubitat.
YoLink lists Home Assistant for this device. The official Home Assistant YoLink integration covers the previous model of the same product (YS5008-UC, FlowSmart All-in-One).
The Z-Wave JS device database lists the ZAC36 (Zooz Titan Water Valve Actuator) and Zooz lists Home Assistant among its compatible hubs.
Zooz lists SmartThings as a compatible hub and publishes an Edge driver for the ZAC36.
The device measures water flow and usage.
YoLink FlowSmart All-in-One Water Meter & Shutoff manufacturer product page →The cited listing is the 3/4-inch pipe variant. It does not verify fit for every size in the broader catalog entry.
Document check only; not a hands-on test or verification of every regional or firmware variant.
The ultrasonic meter reports the meter reading, water usage per day, per month and per use, and the water temperature.
Sends freeze warnings, and the app sets a high and low water temperature alert range.
A built-in temperature sensor (-40 to 257 F) can trigger custom alerts and automations when temperatures drop near freezing.
The leak threshold, maximum usage and maximum duration per use are set on the device with an optional auto shutoff, and schedules and timers run on the device with no internet. YoLink also states automatic shutoff keeps working during internet or power outages.
The included wired leak probe closes the valve even if the hub or all wireless communication is down, so it works as a standalone leak stop.
Includes a 4.75 ft wired water probe on a 3.5 mm input, extendable with a headphone-type extension cable. After a leak the valve stays closed until you press the button.
Zooz sells an optional backup battery pack (smart power bank) that keeps the Titan powered during an outage and shuts the valve off before the battery runs dry.
YoLink states up to 10 years of battery life for its actuators and sensors with the Device-to-Device and Radio Wake-Up technologies.
Non-rechargeable lithium battery, included. Replacing it means opening the battery cover and reconnecting the battery wires.
Runs on a built-in 3.6 V lithium battery and has no AC adapter.
Runs on the included 12 V DC, 1 A power supply (ETL certified) with a 9.5 ft cord. If power is lost the actuator stays in its last position.
Ultrasonic meter and motorized ball valve in one body that is plumbed into the pipe with female NPT fittings.
Zooz states 6 N·m, and says it stress-tested the actuator for more than 20,000 actions at 8 N·m of resistance. A normal valve needs about 1.5 to 3.5 N·m.
Sold as separate 1/2" (YS5018-15), 3/4" (YS5018-20, this listing), 1" (YS5018-25), 1-1/4", 1-1/2" and 2" models (DN15 to DN50).
Quarter-turn ball valves only, not gate valves or 180 degree valves, and not CPVC pipe. It needs 3 in of clearance each side of the valve center, 1.25 in between the handle and the pipe and 1 in between the pipe and the wall.
The Valve Maintenance function cycles the valve on a weekly or monthly schedule set in the app, and it can be disabled.
Check-in mode turns the valve about 1/8 of a turn on a schedule you set with the Auto Test parameter (every 30 days, for example) to confirm it still moves.
