EWPE Wi-Fi App – Troubleshooting and Setup Guide


Purpose

This guide is intended to support technicians and installers in resolving common issues encountered during the setup and configuration of devices using the EWPE Wi-Fi App. It includes practical troubleshooting steps, recommended router settings, and a simplified error code reference.


Common Setup Scenarios and Solutions

1. Device Hotspot Not Detected

• Ensure the device is powered on.

• Perform a proper reset (typically by holding the reset button until the indicator flashes or beeps).

• Look for a Wi-Fi network name such as `GR-AC-XXXX` or an 8-character alphanumeric code (e.g., `8ab23456`) in your phone’s Wi-Fi list.



2. App Fails to Connect to Device

• Confirm your phone is connected to the device’s hotspot.

• Disable mobile data during setup to avoid interference.

• If using a Wi-Fi 6 router, access the router settings and change the encryption mode to WPA2-PSK or WPA/WPA2 mixed mode.



3. Device Not Communicating with App

• Disable AP Isolation or Privacy Mode in the router settings.

• Disable MAC address filtering or add the device to the router’s whitelist.

• Enable WMM (Wi-Fi Multimedia) for optimal performance.

• Ensure the router is broadcasting a 2.4GHz signal (not 5GHz).



4. Device Appears Offline in the App

• Reconnect your phone to the home Wi-Fi network after setup.

• Check that the router is not exceeding its maximum number of connected devices.

• Verify the Wi-Fi password is correct and does not exceed 16 characters.

• If issues persist, test the setup using a mobile hotspot.

Mobile Hotspot Test (Diagnostic Step)

1. Use Phone A to create a 2.4GHz mobile hotspot.

2. Connect Phone B to the hotspot.

3. Open the EWPE App on Phone B and attempt device setup.

4. If successful, the issue likely lies with the original router configuration.

 

Bluetooth Setup Tips

• Ensure Bluetooth is enabled on the mobile device.

• Restart the EWPE app and toggle Bluetooth off and on.

• Grant the app location permissions if prompted.

• If setup fails, reset the device and try again.

Error Code

Description

Recommended Action

SD03

App attempts to connect to device hotspot

Ensure the device is powered on and properly reset. Check the phone’s Wi-Fi list for a hotspot named `GR-AC-XXXX` or similar. If not visible, power cycle the device and retry.

 

SD06

Device responds to app

If using a Wi-Fi 6 router, access the router settings and change the encryption mode to WPA2-PSK or WPA/WPA2 mixed mode to ensure compatibility.

 

SD10

App checks if device is online

Reconnect to home Wi-Fi. Ensure the router is broadcasting a 2.4GHz signal and verify the Wi-Fi password is correct and under 16 characters. Check DHCP settings to allow enough device connections.

 

ZD03

App receives info from router

Enable broadcast settings in the router admin panel. Reduce interference by changing Wi-Fi channel or relocating the device.

 

LY01

App connects via Bluetooth

Ensure Bluetooth is enabled. Restart the app and toggle Bluetooth. Confirm location permissions are granted to the app.

 

LY08

App sends info to device

Use a 2.4GHz Wi-Fi network with a password no longer than 16 characters. Test using a mobile hotspot to rule out router issues. Adjust router settings or consider replacement if needed.

 


Additional Troubleshooting feedback to be aware of


App Connection Issues

  • Password characters unusual (recommend only using letters and numbers)
  • Phone or Tablet device not allowing access through EWPE App (when completing system search, need to access App settings and approve EWPE app and/or turn setting off and back on again)

Braemar Product Connection Issues

  • Wrong Wi-Fi Module device connected to product
  • Wi-Fi Module device connected in wrong PCB port
  • Modem / Router distance to Module device longer than recommended 10 meters (poor signal location)
  • Wall control or Wi-Fi Module device not reset in the recommended allowed time frame for pairing
