reboots when using jura wifi dongle

[pvtex]

Hi,

i am trying to use the jura wifi dongle with the esp32 inside. when i use your code i get a watchdog timeout right after wifi scan has started. this happens a few time and then the esp32 starts in safe mode. what do i have to do to get the dongle running with your code?

found the solution. first change the beginning of the yaml file:

substitutions:
  devicename: jura-wifi
  friendly_name: Jura-Wifi
  device_description: Jura Coffee Machine

esphome:
  name: $devicename
  comment: ${device_description}
  platformio_options:
    upload_speed: 115200
  includes:
    - jura_coffee.h

esp32:
  board: esp32dev
  framework:
    type: arduino

then i needed to edit the jura_coffee.h file: in the first line:

#include <esp_task_wdt.h>    
#define WDT_TIMEOUT 20

and the new setup function

void setup() override {      
    this->set_update_interval(60000);      // 600000 = 10 minutes // Now 60 seconds     
    esp_task_wdt_init(WDT_TIMEOUT, true);  // enable panic so ESP32 restarts      
    esp_task_wdt_add(NULL);                // add current thread to WDT watch      
}

and the new loop function:

void loop() override {      
    delay(8);       
    esp_task_wdt_reset();     // Added to repeatedly reset the Watch Dog Timer       
}
