This will turn out to be a bit more involved that just adding the ADS1115 through the dashboard. To get this to work correctly you will have to use the MQTT API You can see an example here of using the MQTT API with a python script on the Pi here Basically just replae the bits where I read the DHT sensors with your code to read the ADS1115, then convert it to a temp and upload to Cayenne. Let me know if you have any questions, I have this sensor and can test your code.
