Starting
- M5Stack Temp/Hum Wifi & MQTT client v1.1.0
-- on ESP32-C0EC
- Initializing WiFi
...
-- Connected to stairway_to_lan
-- IP-Address 192.168.x.y
- Initializing MDNS responder
-- MDNS started: ESP32-C0EC.local
- Initializing MQTT client
-- MQTT publish interval in seconds: 900
-- connected
- Initializing ESP32 Deep Sleep
-- in: 15 Seconds
-- duration: 15 Minutes
```
### SETUP:
#### #include "credentials.h":
adjust the credentials in the header only library, at least WiFi credentials
```
// ##### WiFi credentials
char *wifiSsid = "stairway_to_lan";
char *wifiPassword = "top_secret_123";
// ##### DHT credentials
//=> see rz_dht.h|cpp
// ##### MQTT credentials
IPAddress mqttServer(192, 168, x, y);
int mqttPort = 1883;
char *mqttUser = "Tasmota_User";
char *mqttPwd = "Tasmota_Password";
// run MQTT and do intervall publishing
bool enableMQTT = true;
// Intervall Timer (Milliseconds) for MQTT publish
//const long mqttInterval = 300000; // 5 Mins
const long mqttInterval = 900000; // 15 Mins
//const long mqttInterval = 1800000; // 30 Mins
//const long mqttInterval = 3600000; // 60 Mins
// ##### Webserver credentials
// run webserver
bool enableWebserver = false;
int webserverPort = 80;
// ##### System credentials
// time sync
char* ntpServer = "de.pool.ntp.org";
// offset in seconds between your time zone and GMT
long gmtOffset_sec = 3600;
// offset in seconds for daylight saving time.
int daylightOffset_sec = 3600;
// run deepsleep and e.g. run mqtt publish after wakeup
bool deepSleep = true;
// Time ESP32 will go to sleep (in milliseconds)
//const unsigned long long TIME_TO_SLEEP = 0;
//const unsigned long long TIME_TO_SLEEP = 300; // 5 Mins
const unsigned long long TIME_TO_SLEEP = 900000000; // 15 Mins
//const unsigned long long TIME_TO_SLEEP = 1800; // 30 Mins
//const unsigned long long TIME_TO_SLEEP = 3600; // 60 Mins
// Serial Speed
const uint32_t SERIAL_SPEED{115200};
// check for firmware updates
const bool CHECK_FIRMWARE = true;
// do firmware update => not yet implemented
const bool DO_FIRMWARE_UPDATE = false;
