Misquitto broker Integration "This integration has no device"

Hello,
I just installed Hassio onto a Raspberry Pi and have been trying to get Misquitto MQTT to work through the Integration under Configuration. I have followed the Misquitto guide and HA did discover the broker, and it did give me a Success card. I have left Misquitto with the default config in the Plug-In Manager.

However, the Integration does not show any of my connected devices. I have a light switch and a garage door that I have configured. The Misquitto plug-in log is showing that these device are connecting, along with what I assume is HA also connecting to it. Under the HA log, I see the following errors:


and under the Misquitto plug-in log I see

Is there something I have done wrong? Should my devices show up under the MQTT Integration page, or how should I configure my devices? Is there any YAML I need to edit for it to work?

Thanks,
Avery
