Build

To build the project you have to provide a secrets.h header file with the following:

#define SECRET_WIFI_SSID ("your SSID")
#define SECRET_WIFI_PASSWORD ("the wifi password")
#define SECRET_MQTT_HOST ("MQTT host")
#define SECRET_MQTT_PORT (8883)
#define SECRET_MQTT_USER ("your mqtt user")
#define SECRET_MQTT_PASSWORD ("mqtt password")
#define SECRET_FINGERPRINT ("SHA1 fingerprint of the TLS certificate used")
#define SECRET_MQTT_TOPIC ("the/topic/where/to/send/data")
#define SECRET_MQTT_CLIENT_ID ("client id")
