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-RBS. 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!

2. 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."

FAQ

---

1. What type of junction box is the Orb-RBS 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-RBS?

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. Why does the app show the device as offline after clicking "Enable Pairing Mode"?

After enabling Pairing Mode in the eWeLink app, the device enters Network Pairing Mode (indicated by a "two short, one long" LED pattern) and shows as "Offline." Short-press the device button to restore "Online" status.

5. Why can't the Orb-RBS 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. What is Matter, and why is it important?

Matter is a new smart home connectivity standard that enables devices from different brands and ecosystems (like Apple HomeKit, Google Home, Amazon Alexa, SmartThings, etc.) to work together seamlessly. Orb-RBS supports Matter, allowing easy integration and cross-platform control.

7. Does Orb-RBS require a neutral wire?

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

8. Which apps or ecosystems is Orb-RBS compatible with?

With Matter support, it works with:

• Apple Home
• Google Home
• Amazon Alexa
• Home Assistant
• Samsung SmartThings

 

Troubleshooting

---

1. Why does the app show the device as offline after clicking "Enable Pairing Mode"?

After enabling Pairing Mode in the eWeLink app, the device enters Network Pairing Mode (indicated by a "two short, one long" LED pattern) and shows as "Offline." Short-press the device button to restore "Online" status.

2. Device not showing up during Matter pairing.

• Make sure the device is in pairing mode.
• Make sure your mobile device and Orb-RBS are on the same 2.4GHz Wi-Fi.
• Update the app and OS of your phone and smart home hub.

3. Device is offline or not responding in the app.

• Check if the Wi-Fi network is working normally.
• Reboot your router and the Orb-RBS.
• If needed, reset the device and re-pair it.

4. Can't control Orb-RBS from the voice assistant.
