How to Troubleshoot connection with WLED.

Here are some settings to check that will help fix WLED connection issues. 

• Make sure that your WLED controllers are connected to the same Wi-Fi network as your computer (the ssid/name of the network should be the same).

• WLED version 0.13.3 seems to work best with LIGHTLINK.

• In the Wi-Fi settings for the WLED controller, there is a setting called "mDNS address". For auto-discovery, this address has to contain 'wled'. This is not necessary for manual addition.

• If your controllers aren't detected automatically, you can add them manually by clicking on the "How to Connect WLED" instruction at the bottom of the LIGHTLINK screen. Enter the IP address and name for the controller and click "ADD". If the add is successful, the lights will turn green.

• In the Wi-Fi settings for the WLED controller, there is a setting called "Disable Wi-Fi Sleep". Checking this can help with connection to LIGHTLINK, especially if your controllers are on a version higher than 0.13.3.

• Sometimes, a WLED controller will only "advertise" itself on the Wi-Fi network for a short while after booting up. Because of this, the auto-discovery sometimes works better if you power your WLED controller off and then on again, then open LIGHTLINK about 5-10 seconds later. Note: This isn't necessary if you auto-add your controllers

• If you get a warning about not having "Bonjour" when you start up LIGHTLINK, you will need to follow the instructions to install Bonjour in order for auto-discovery of WLED devices to work. This is not necessary for manually adding them.

• In the Sync Settings for the WLED controller, there is a setting called "UDP Port". This needs to be 21324 for LIGHTLINK to work. Note: In those same settings, "Receive UDP Realtime" must be checked.
