Apologies, I’m sure I’m doing something very basic the wrong way here.
When I want to add a new network device to my HA dashboard, I go into the Unifi integration, hit configure on the default hub, then find the device in the dropdown list, tick it, then go through to the third page of the config, find the device again in that list, tick it, and I have all the switches/entities that I need.
This was working fine until the other day, now for some reason the dialog box for configure is too small to be able to see all of the dropdown list. The entries on the list extend off the top of the dialog box. Scrolling doesn’t help, I still can’t see what’s at the top of the list.
