RPI3, I2C Hat and BME280 sensors with Cayenne

HI, I have an RPI 3 running Cayenne and I have purchased 4 BME280 Sensors, an I2C Shield and a 4 channel relay. I am new with this and need help getting this setup. Any help is appreciated thanks.

You will need to first have all 4 BME280 sensors reading on RPI using a python script. Once done you can use GitHub - myDevicesIoT/Cayenne-MQTT-Python: Python Library for Cayenne MQTT API to send the sensor data to cayenne.

Thank you so much for the help, I was able to get one of my sensors to read finally. I am still having trouble getting all four to read at once, do you have any thoughts on that? Again thank you for the help.

can you share the code you are using for one sensor.
