04 ‐ The Boot Process

Boot Up Process and LED Indicators

As the clock goes through the boot and startup processes, it will flash certain LEDs to indicate progress. For a normal boot, you should see the following:

Process	LED Indications
Wifi Connecting	The 12 o'clock hour LED will light up
MQTT Connecting	The 3 o'clock hour LED will light up
OTA Updates Enabled	The 6 o'clock hour LED will light up
LED Self-Test	All minute LEDs will light up in sequence, followed by the hour LEDs
OTA Port Broadcasting	The 12, 3, 6 and 9 o'clock hour LEDs will light for a few seconds
Current Time Displayed	As soon as the clock receives the current time, it will be displayed

Note that there may be a few second delay between the time the OTA Port broadcast finishes and the time is displayed. The clock will request that Home Assistant (or the other MQTT-enable automation system) transmit the current time. Once it is received, the time will be displayed.

If the clock does not boot up normally, you can use the above indicator lights to help determine at what point the boot/setup is failing. For example, if the 12 o'clock hour LED lights up and stays lit and nothing else happens, it indicates that the clock is having a problem connecting to your WiFi.
