Notes:

  - Hue lights still slap, "just work", and have proved to be reliable over time. They are a big upgrade over non-dimmable, non-temp-changeable bulbs, or buzzing dimmer switches from ages past.

  - Home Assistant's UX is poor

  - I should probably try some of the temp control and security camera tools

Most importantly: These systems can be useful and have a good design without being cloud. A microcontroller and good user interface can be a big upgrade over a "dumb" system, without evoking the internet, or a Linux etc operating system.
