  2. Log in to your account (or create one if you haven't).
  3. Navigate to the Device Management section and click Add Device.
  4. Enter the Device Code displayed on your reTerminal E1003 screen to complete the binding process.

Step 3. Create Content on the Platform​

  1. Go to the Home Page select a template you want or Workspace to create your work from scratch.
  2. Click this link to learn how to use HMI Platform if you have question.

Step 4. Deploy Content to Device​

  1. Once your design is ready, click the Preview button to check how it looks.
  2. Click the Save or deploy button.
  3. Select your bound reTerminal E1003 from the list.

Troubleshooting​

Q1: Device Won't Power On​

  • Ensure the power switch is in the ON position
  • Connect the USB-C cable to charge the device
  • Check if the red LED is always on (indicating charging)
  • If using battery power, ensure the battery is properly connected and charged

Q2: Can't Connect to Wi-Fi​

  • Verify you're entering the correct Wi-Fi password
  • Ensure your Wi-Fi network is operational
  • Check if your Wi-Fi router supports 2.4GHz networks (5GHz is not supported)
  • Try positioning the device closer to your Wi-Fi router

Q3: Display Not Updating​

  • Press the refresh button to manually trigger an update
  • Verify the device is connected to Wi-Fi (no disconnection icon in the corner)
  • Check your SenseCraft account to ensure the dashboard is properly deployed
  • If the problem persists, try restarting the device
  • If the device still does not respond after restarting, re-flash the corresponding firmware on the SenseCraft HMI platform and check whether the device can refresh normally

Q4: Network Connection Lost​

  • The device will automatically attempt to reconnect to known networks
  • When reconnected, the Wi-Fi disconnection icon will disappear
  • If unable to reconnect, follow the Network Reset procedure above

Q5: Cannot Find Serial Port (COM) on macOS​

If your Mac doesn't recognize the reTerminal via USB, follow this compact guide to install the CH340/CH340K driver:

Step 1. Download and Install the Driver Download the driver from the official WCH page and run CH34xVCPDriver.pkg.

tip

If macOS blocks the installation, go to System Settings → Privacy & Security, scroll to find the blocked WCH software, and click Allow.

Step 2. Enable Driver Extension (Critical) Open the CH34xVCPDriver app from Launchpad, click Install, then go to System Settings → General → Login Items & Extensions → Driver Extensions. Toggle CH34xVCPDriver Extensions to ON (blue).

Step 3. Connect and Verify Ensure the device power switch is ON and use a data USB-C cable (not charge-only). Open Terminal and run:

ls /dev/tty.wch*
# Expected output: /dev/tty.wchusbserialxxx

If you see the device path in the output, the driver is correctly installed and your reTerminal is ready for use!
