I have an interesting problem. Since updating to the December release of home assistant on the 16th every 5 to 10 minutes my devices show unavailable on my zha network then about 10 seconds later go back to their valid state. It is the same symptoms of what would happen if I were to unplug and plugin the skyconnect.
I am using a USB 2.0 extension on USB 2.0 ports on a mini PC U59 with a bare metal install.
Zero issues until the December release.
