ZigBee entities sometimes do not show up until after reboot

I’m running the latest stable HA on an RPi Zero W with the latest stable Docker, and using ZigBee with an HUSBZB-1. On the very first run of HA, I was able to add devices quickly, but none of the entities showed up until I restarted the Docker container. Yesterday I was able to add a device, and it picked the entities up immediately. Today I paired another plug immediately, but the entities again did not show up until I restarted the container. Can someone point me in the direction of what to look at to see what is going on?

I don’t have a Pi Zero, but as far as I know the speed are more or less equal to a Pi 1. And HA on a Pi 1 is very slow. Maybe you don’t wait long enough for it to show up ?

Pi zero is not recommended hardware.
