Configuring WiFi

The first time you run it, you need to configure the WiFi, for that connect to the “Clockwise-Wifi” access point with the password 12345678 via your smartphone or laptop, click “Configure WiFi” and select your AP, put in your password and your timezone and save. The timezone must be one of the listed here e.g. America/New_York, America/Sao_Paulo, Europe/Paris, Asia/Dubai, etc. so that the clock can connect to an NTP server to get the correct time. It is important to use a 2.4GHz WiFi, it will not work on 5G.
