Adding a custom widget to a Raspberry

Hello, I have an issue with my project.
I need to connect a line chart to my Raspberry but I need to enter a code location and a channel in order to add this widget.
What is the code location and how do I find it ?
Thank you in advance :slight_smile:

You cannot add a custom widget to raspberry pi added to cayenne using the link setup.
You will need to use the python library to do so https://github.com/myDevicesIoT/Cayenne-MQTT-Python

Thank you, it’s done :wink:
