SHT30/DS18B20 errors and warnings in the logs

my means: just re solder the resistors pad on PCB. also re solder the ESP32 module pins.

my code is update every 1 minute, you can change to smaller.
KC868-A2 1-wire circuit, only use by 4 resistance for two GPIO ports.
R11,R12: 4.7K
R13,R14: 100ohm

Maybe you can use electric ferrochrome to repair the resistor pad and the gpio pad related to the esp32 module.

Can you show the whole board schematic? I'm wondering if any pull-up resistors exist on the IN1/IN2 inputs. I use them to read the RPM of my fans and they have this wiring diagram. A pull-up resistor is needed there. But I didn't use any pull-up resistor, I just connected the wires to the inputs and I got feedback on the fan RPM. I'm not sure, but maybe this affects the operation of the sensors.

Looking at the diagram, which resistor should I use? I use 24V power supply for board A2, then I have to solder a pull-up resistor between IN1/IN2 to +24V, should this resistor be 24kΩ? Or should the pull-up resistor value be different and not tied to 24V?

I've been running tests for a while and have figured out something. The Kincony A2 board works fine with the DS18B20 sensor if A2 is not in the control box. Even if I put the board in the box where it should be, everything works fine until I start the fans. A 0-10V signal controls these fans, and the controller is connected to the Kincony A2 via RS485. The Kincony A2 also reads the RPM of these fans.

Is there any interference or conflict between the 0-10V controller and the Kincony A2? Maybe the Kincony A2 is not protected against interference? Is there any way to fix it?

Okay, thanks. Are there any options to protect A2 from external interference?

maybe you can test add another power supply for KC868-A2. Not use same power supply for your all devices.
