MCP23017 not working with raspberry after mqtt update

I’ve been using mcp23017 with my raspberry since before the mqtt update for my home domotic project. i have so many to controls so i needed a port extension and had to use this one, since the latest update my project is down.
Can anyone help me?
Thanks in advance

currently, extensions are not supported with agent 2.0. have a look at this Raspberry Pi Agent 2.0
if you still want to add, you can try with GitHub - myDevicesIoT/Cayenne-MQTT-Python: Python Library for Cayenne MQTT API
