Getting the CAST-1 wiki ready before launch

The CAST-1 plugs into the line-in on speakers you already own and turns them into a Music Assistant player. It launches in about a month, so I spent a day finishing its wiki. Along the way I found a sensor listed in our own docs that no firmware has ever exposed.

Building an air quality LED indicator for the AIR-1

The AIR-1 has three onboard RGB LEDs, so I made them show air quality at a glance. The feature itself is small. Getting there took longer than it should have, because I kept fixing things that weren't the problem. These are the dead ends and where it ended up.

The CAST-1 got a new DAC component and WizMote support

ESPHome 2026.6.0 added a built-in PCM5122 component, so we moved the Apollo CAST-1 off the community one we'd been using and added WizMote remote control in the same update. The move wasn't optional, the old component stopped loading on 2026.6.0, and the swap shipped with a silent-audio bug I had to chase down.
