- Need to install the following dependencies
- Adafruit BMP085 Library
- CayenneMQTT
- ArduinoJson Use version 6.13.0
- TinyGSM
- Set the Cayenne authentication info to match the authentication info from the Dashboard.If you don't have an account, then create an account
- After logging in, you will see the dashboard, click Add new in the upper left,Choose Generic ESP8266,Then you can see the MQTT username, password and ID you need to use,Replace it with the definition in
main.cpp - Set the network name and password.
- Compile and upload the sketch.
- A temporary widget will be automatically generated in the Cayenne Dashboard. To make the widget permanent click the plus sign on the widget.
- By default, GSM is used to upload sensor data. You can also change it to ESP32 to upload. You only need to host the USE_GSM macro in the sketch.
