Hello everybody.
Im new to programming. Im trying to control blinds with esp8266 via mqtt.
I can send recieve with mqtt also i use some sensors.
I tried to mix them. Control blinds (automated with light sensor and manuel with home assistans + dth sensor + ultrosonic sensor for reset blinds + store stepper count to eeprom)
i got hw watchdog error. (with and without connect any cable)
Here is my code.
#include <AccelStepper.h>
#include <EEPROM.h>
#include <ESP8266WiFi.h>
#include <PubSubClient.h>
#include <DHT.h>

#define echoPin 2
#define Motor1_Dir 5
#define Motor1_Step 6
#define DHTPIN 7
#define DHTTYPE DHT11

const char* password = "x";
const char* mqtt_server = "x";
const char* mqttUser = "x";
