Connection Issues

Key things to do while debugging connection issues:

  1. Close the app and re-open the app after any change.
  2. After you connect the timer to your WiFi network, make sure to reconnect your phone to the same WiFi network.

Initial Connection to WiFi

  1. If you can’t see your WiFi on the list or the list is too long, disconnect and reconnect your phone from the OS network to update the list. 
  2. You can also type in the WiFi SSID name manually and connect.
  3. After selecting the WiFi and entering a password, the timer should reboot and indicate your new WiFi connection by illuminating LED4 in < 20 seconds.
    1. If it does not come on, it likely means the password was incorrect. 

“Scan for device” is missing on the App’s main page 

This seems to happen when the app is not able to get to the internet or a setting has been cached and the cache isn’t clearing properly or hasn’t cleared yet. Here are some things to try.

  1. Your phone is not the internet; turn off your cellular data and make sure you’re connected to the same WiFi network that you set the timer to use.
  2. Check that LED4 is illuminated. If not, re-do the steps to connect your timer to your home WiFi network.
  3. If nothing seems to be working, try the following:
    1. Turn off your cellular data and make sure you’re connected to the same WiFi network.
    2. close all browsers on your phone.
    3. uninstall the app from your phone and re-install it.  
    4. close the app, shut down the phone and restart it. 
    5. Close the app and re-try again in an hour. 
  4. Once it works and discovers the timer, it’ll always work without having to do any of the preceding troubleshooting items. 

“Scan for device” does not detect the timer

  1. Make sure you are connecting the timer to your primary WiFi network, not a guest network. Some routers do not properly allow the discovery through a guest network. 
  2. Make sure LED4 is Illuminated; if it is not, then the timer is not connected to the WiFi network; start the setup process again (make sure WiFi password is correct), power off and on the timer, if needed.
