Clicker requires WiFi connection to work. Since it doesn't have its own interface, you should use Panel to change WiFi settings. Here's how to do it.
IMPORTANT: you can change WiFi settings only if Clicker does not connect to WiFi. In this case it enters "Setup Mode", otherwise it works normally.
1. Connect Clicker to the PC. It should start blinking. Wait until it starts doing 1 blink every 5 seconds. It means that Setup Mode was entered.
2. Open Setup Mode page in Panel: round button at the bottom right corner of the screen.
3. Connect to the Device. Find it by Device ID in the browser pop up window.
4. Enter and save WiFi name and password. Check the logs and wait until you see "WiFi manager: WiFi test success". Now you can unplug Clicker and connect it to the iPhone.
After these steps Clicker will use the new WiFi configuration.
