Hello, Finally implemented the project with PCB from JLCPCB and programmed the ESP32. Notes on Wiring & Configuration : HTUD21 wired via GX12 PROBE1 wired via 3 PIN audio jack CH3 mode is set on CH1 DH1 not wired yet (or with simple resistors for testing purposes) I have not ordered the Dew Heater yet and will try to build one by myself with 1/2W or 1W resistors, but just had some issues before that : 1. When everything is started with PROBE1 sensor wired, I get the temperature from main HTUD21 sensor...
