LEDs - tbnobody/OpenDTU GitHub Wiki

On the board with the ESP32 - besides the OLED display - also two green LEDs* are controlled. These LEDs are already installed on the breakout board from blinkyparts.com.

• LED1 (left) for status network:
  • Blinking: WLAN is connected, but NTP and MQTT (if activated) are not connected.
  • On: WLAN, NTP and MQTT are connected.
  • Off: WLAN is not connected.
• LED2 (right) for inverter status:
  • Blinking: All inverters are reachable, but are not producing.
  • On: All inverters are reachable and producing.
  • Off: At least one inverter is not reachable. Note: Only inverters with polling enabled are considered.

* Note on hardware:

• LED1 is controlled via pin G25.
• LED2 is controlled via pin G26.
