I’m working on a custom component to track devices based on their status within Clearpass. It works Ok, but I could use some pointers on how to improve it. One, the tracker seems to be very delayed in scanning and updating hosts. The other issue I have is when get_device_name is called and the name is returned, it’s not updating known_devices.yaml with the name. Also, the get_extra_attributes is not returning the IP of the device, but that is less of a concern.
Thanks in advance!
