The primary differences between the YS4909, YS5001, and YS5003 Valve Controllers are in their battery life and power options:

YS4909 (Valve Controller 1): This valve controller has a battery life of up to 2 years, and it relies on battery power.

YS5001 (X3 Valve Controller): This valve controller features an extended battery life of up to 10 years, providing longer-lasting performance without the need for frequent battery replacements.

YS5003 (Valve Controller 2): Similar to the YS4909, this valve controller has a battery life of up to 2 years. However, it also includes an AC adapter, offering an alternative power source besides battery power. It is also more powerful than YS4909.

 Yes, the YS5003 Valve Controller 2 is compatible with 2 wire U.S. Solid valves only.

Yes, it can be used outdoors. The YoLink valve controller has an IP rating of IP66, which means it is dust-tight and protected against powerful water jets.

The YoLink valve controller uses 4 AA batteries, providing a 6VDC power supply. These AA batteries are commonly available and low-cost. The valve controller's circuit board includes a power boost IC, which converts the 6VDC input to a 12VDC output, allowing it to operate the 12V valve effectively.

Yes, YoLink offers lead-free valves in various sizes, including 0.75-inch, 1-inch, 1.5-inch, and 2-inch options. 

The IP rating of the Valve Controller is IP66, the IP rating of Motorized Ball Valve is IP65.

Yes, the YoLink Valve Controller supports YoLink Control, for example, enabling you to pair it with a YoLink water leak sensor. When the sensor detects a water leak, the valve will automatically shut off without requiring power or internet. However, if there is no internet connection, you won't be able to control the valve controller through the YoLink App, and Alexa routines will not function either.

a. The controller directly controls the opening and closing of the motorized valve, ensuring accurate operation and preventing position deviations that can occur with a manipulator (such as incomplete opening or closing).

b. Motorized valves can be used to control water pipes up to 2 inches in diameter, providing flexibility for various pipe sizes.

c. The motorized valve is directly connected to the water pipe for installation, avoiding potential issues related to different pipe valve sizes that can arise when using a manipulator (e.g., insufficient height of the mounting bracket).

Before attempting the D2D pairing, make sure your valve is closed and you can follow the instructions in this video for the pairing process. If you still encounter issues after following these steps, consider reaching out to YoLink customer support for further assistance.

 No, it is not necessary to cut off the pipeline for motorized valve installation. The installation depends on the actual installation scene. Some water pipes have threaded connections, allowing the motorized valve to be directly screwed in. You can install the valve yourself or ask a plumber to handle it.

There are two ways to close the valve when the sensor detects water:

1. Create automation in the YoLink app (requires internet connection):

When: Water leak sensor detects a water leak (triggers an alert)

Then: Valve controller closes the valve

2. Set up YoLink Control:Make sure the firmware of the valve controller is 090e or newer (no internet required) - 

First, close the valve. Next, press and hold the set button on the water leak sensor until the green LED starts blinking rapidly. Then, press and hold the set button on the valve controller until its green LED also blinks rapidly. This establishes a direct connection between the devices without the need for an internet connection.

Yes, you can set up YoLink Control between the Power Fail Alarm and the valve controller to turn off the water control valve during a power failure. Follow these steps:

Close your valve.

Press and hold the set button on the Power Fail Alarm for 5 seconds until the green LED starts blinking rapidly.

Press and hold the set button on the valve controller for 5 seconds until the green LED starts blinking rapidly.

By following these steps, you can configure the Power Fail Alarm to automatically turn off the water control valve when a power outage occurs.

First, make sure your YoLink app is up to date. Then, remove the old batteries and press the button several times to discharge the capacitors before installing new, non-rechargeable batteries. If the issue persists after these steps, please contact YoLink customer support for further assistance.

The "still open" notification is designed for situations like watering, where it serves as a reminder to users that the valve remains open. If you have set up this feature on your main valve, you may receive this notification even if you did not close or open the valve. To avoid this, you should disable the "open remind" feature for your main valve.

The reversed open and closed positions on your motorized valve are likely due to misaligned connectors between the female and male 2-pin connectors. To fix this issue, ensure that the slot between the connectors is properly aligned. This should correct the valve's operation and display the accurate status in the app.

Yes, the valve controller can be mounted on either side of the shutoff valve, providing flexibility for installation based on your specific setup and requirements.

 First, make sure that the center of the valve shaft and the center of the Bulldog's motor shaft are aligned as shown in the manual (the bracket may be flipped around 180 degrees and then they should be able to mount it properly). Proper alignment is crucial for optimal leverage. If they are aligned and the issue persists, try adjusting the valve handle's position. Install the two studs that shift the water valve handle slightly off-center from the actuator arm, moving it towards the closed position. This adjustment gives the manipulator more range to overcome the force required to close the valve completely at the end of the 90-degree rotation. Although this might result in the valve not being fully open (possibly missing around 5 degrees), it should still allow for sufficient water flow.

Yes, there is a larger bracket available for the Bulldog system, which can accommodate a 1.5-inch water main. You can find the HC2XXL custom bracket by visiting this link: https://shop.yosmart.com/products/econet-bulldog-custom-bracket-hc2xxl

To connect your valve controller and Bulldog ball valve to Google Assistant, follow these steps:

Open the YoLink app and go to "Smart" -> "Scene" to set up a new scene for opening the valve. Add behavior: "Valve controller" -> "Open".

Open the Google Home app and reconnect to YoLink. Next, go to "Routine" -> "Set up a new routine." Create a custom command for Google Assistant, such as "Hey Google, open the valve." Then, add action: "Adjust Home Devices" -> "Adjust scenes" -> add the "open the valve" scene you created in the YoLink app.

By following these steps, you'll be able to control your valve controller and Bulldog ball valve using voice commands through Google Assistant.

Yes, you can manually operate the ball valve with the Bulldog valve controller installed. To do so, push and hold the clutch pin, then use the valve handle (recommended) or the robot handle to open or close the valve.

You should not scan the QR code on the Bulldog valve robot itself. Instead, scan the QR code on the YoLink Valve Controller. The valve controller is designed to work with the YoLink Hub, and it powers and controls the Bulldog valve robot. By scanning the QR code on the YoLink Valve Controller, you should be able to add it to your YoLink account without any issues.

The Bulldog Valve Robot is not waterproof. If you need to protect it from water or moisture, we recommend using a weatherproof box to cover both the Bulldog and the valve controller.

The website will provide you with the necessary information to determine the appropriate bracket size for your 1 ⅝" OD copper pipe.

You can set up an automation in the YoLink app to open the valve after all water sensors stop detecting water. Here's how:

Go to YoLink app -> Smart -> Automation -> create a new automation.

Choose the trigger: "When valve - close."

Add Behavior 1: "Break if when water sensor 1 - detected water."

Add Behavior 2: "Break if when water sensor 2 - detected water."

Continue adding similar behaviors for all your water sensors.

Add the final behavior: "Valve - open."

This automation will open the valve when it is closed and all the water sensors have stopped detecting water.

 To set an alarm for valve opening and closing notifications, follow these steps in the YoLink app:

Open the YoLink app and navigate to the "Smart" section.

Tap "Automation" and create two separate automations: one for valve opening and another for valve closing.

For Automation1 (valve opening):

a. Set the trigger: "When device actions" -> "Valve controller" -> "Open".

b. Add the desired behavior: "Notification" -> "Custom notification content".

c. Select the alarm strategy: App, email, and/or SMS, as preferred.

For Automation2 (valve closing):

a. Set the trigger: "When device actions" -> "Valve controller" -> "Close".

b. Add the desired behavior: "Notification" -> "Custom notification content".

c. Select the alarm strategy: App, email, and/or SMS, as preferred.

By following these steps, you'll receive notifications when the valve is opening or closing based on your chosen notification preferences.
