Large Home Assistant Installations

Are there any large HA installations out there? I would like to know how you manage everything through the GUI interface.

I currently manage several buildings, but for the sake of a simple example, let’s assume

  • Ten floors, 100 rooms per floor, five devices per room, each with one channel

That’s 5,000 channels to configure. Using the GUI would take weeks for a simple change. At this scale, I could write a program to generate YAML, and maybe that’s how this is done.

I have read that HA is moving away from YAML and going GUI only interface. Is this true?
