I spent this evening doing the least glamorous home-automation chore there is: tidying groups. The porch, the hallway, the bedroom - each a fixture with several bulbs that had drifted onto the dashboard as several identical-looking entities. One control per fixture is the goal. So I grouped them, hid the individual bulbs, and moved on.

Except one of those groups isn’t like the others, and I couldn’t stop thinking about it.
