Wiring Diagrams

Installation Recommendations Since the device needs to be connected to the motor, it is recommended to reserve a switch junction box near the existing electric roller shutter for installation. Wall junction box requirements: Motor Requirements The user must have an electric roller shutter at home and will need to retrofit it to upgrade it to a smart roller shutter. ① The motor used for the electric roller shutter must have a current of less than 1A. ② Motor power supply: AC (100~240V). ③ The motor shall be a 4-wire or 5-wire AC motor (including neutral, forward, reverse, and ground wires) with a built-in forward/reverse rotation limiter. To ensure the safety of your electrical installation, it's essential that either a Miniature Circuit Breaker (MCB) or a Residual Current operated Circuit-breaker with Integral Overcurrent protection(RCBO) with an electrical rating of 1A has been installed before the Orb-ZBRBS. WARNING Please install and maintain the device by a professional electrician. To avoid electric shock hazards, do not operate any connection or contact the terminal connector while the device is powered on!

Check the Device Status

1. Roller shutter direction test

After pressing the switch, check if the roller blind moves in the correct direction. If not, turn off the power, swap the Lout1 and Lout2 wires, then test again.

Important Prerequisite Confirmation:
Please select the appropriate section based on the ecosystem you are using (Matter or eWeLink). Follow the corresponding steps to complete the "Add Device" and "Travel Calibration" operations.

 

eWeLink Ecosystem User Guide 

1. Add Device

① Download the eWeLink App

Please download the "eWeLink" App from Google Play Store or Apple App Store.

② Scan QR code to add the device

Enter "Scan"	Scan the QR code on the quick guide or the device	Select "Add Device"
(If the device exits pairing mode) Long press the button for 5 seconds	Check LED indicator flashing status (Two short and one long)	Select Zigbee gateway
Wait until the addition is done.

2. Travel Calibration

⚠️Using percentage control requires travel calibration. Please select one of the following two calibration options based on your needs.

Users can use the "Travel Calibration" pop-up window in the eWeLink App, or open the "Initial Settings" on the device settings page and then perform "Automatic Calibration" or "Manual Calibration" according to the text instructions in the App.

① Method 1: Automatic calibration

Click "Start Now"

Wait for the automatic calibration to complete

② Method 2: Manual calibration

Click "Start Now"	Click "Manual"
Select "Next" to mark the "fully open" position	Select "Done" to mark the "fully close" position

 

Third-party Platform

The user can perform the calibration operation using the device button. If there is any deviation in the calibration result, the calibration can be repeated until the desired accuracy is achieved.

Travel Calibration 

⚠️Using percentage control requires travel calibration. Please select one of the following two calibration options based on your needs.

Method 1: Automatic calibration

① Press and hold the device button for more than 10 seconds until the LED indicator enters breathing mode. The device will then automatically control the motor for calibration.

Method 2: Manual calibration

① Press and hold the device button for more than 10 seconds until the LED indicator enters breathing mode. Then, briefly press the device button to enter "Manual Calibration" mode.

② Manually open the curtains completely, then briefly press the device button until the LED indicator flashes three times.

③ Wait for the device to automatically close the curtains, then briefly press the device button again until the LED indicator flashes three times. This completes the "Manual Calibration."

④ Control the device through the App and check the fully open or fully closed positions. If there is any discrepancy, you can recalibrate.

FAQ

---

1. What type of junction box is the Orb-ZBRBS compatible with?

2. Can the motor run continuously in the same direction?

No. The motor should not operate in a single direction for more than 2 minutes. To prevent overheating and damage, the device will automatically enter a stop state after exceeding this time limit.

3. Can two or more curtain motors be connected in parallel and controlled synchronously through the Orb-ZBRBS?

No. Due to individual differences in each motor, even if the operating time is the same, the travel distance may not be consistent, making synchronous control impossible.

4. Does the device function as a Zigbee repeater?

Yes, Orb-ZBRBS has built-in Zigbee signal repeater functionality to help improve and stabilize your Zigbee network coverage.

5. Why can't the Orb-ZBRBS perform "automatic calibration" for the curtain motor?
If the motor power is too small, or the curtain type is not a roller blind, roller shutter, or projection screen, it may cause "automatic calibration" to fail. It is recommended to switch to "manual calibration" mode.

6. Does Orb-ZBRBS require a neutral wire?

Yes. Orb-ZBRBS requires a neutral wire for proper installation and operation.

 

Troubleshooting

1. Unable to add the device to the Zigbee hub.

Check if the device is powered and the indicator light is responsive.

Press and hold the reset button for ≥5 seconds to enter pairing mode.

Ensure the Zigbee hub is within range and in pairing mode.

Try restarting the hub and reattempting the pairing process.

2. The curtain cannot be controlled via the app.

Check the motor wiring and ensure the connected load does not exceed 1A.

Make sure the Zigbee network is stable, or try re-pairing the device.

3. The curtain opens/closes in the wrong direction.

Use the app’s Motor Rotation Direction to correct movement.

Alternatively, swap the motor's "up" and "down" wire terminals.

4. The device frequently goes offline or responds slowly.

Check for Zigbee interference or signal obstacles.

Avoid installing the device inside metal wall boxes.

Add more Zigbee routers/repeaters to strengthen network coverage.

5. The curtain does not fully open or close.

Calibrate the upper and lower curtain limits through automatic calibration or manual calibration.
