Improved Version

[SchneHa]

Meanwhile, I improved your HomeKit version. I added HK and webserver support for an air temperature sensor DS18B20 connected to GND, D1 and 3V3 (with 4k7 resistance between D1 and 3v3). Also I added WiFi Manager for easy configuration and changing WiFi credentials without reflashing the module. I added a button connected to D3 (with 10k resistance between D3 and 5V) and GND as trigger button for changing WiFi credentials.
Feeding the watchdog inserted in main loop to avoid sudden reboots.

Hello, could you share your code modifications? I'm interested in feeding the watchdog to increase stability.
Thx and BR

Feeding the watchdog timer is easy:

Insert the following lines:
After "void loop() {":

  ESP.wdtFeed();
  ESP.wdtEnable(0);

Maybe WDT must also be disabled in void setup()
As last line:
ESP.wdtDisable();

Try it out.

If you need more code you have to tell me how to send you a PM.

Thank you for your answer. I suppose that these modifications are also valid to improve stability on "support saltwater version" of Ulrichmai. My email is dvoc0359@gmail.com many thanks.
