Sounds awesome—let’s tighten it up. First, pick one hub: I’d go with Home Assistant or OpenHAB. Add each device as a sensor/actuator there. Then create a single “Game On” scene that does three things: 1) tells the lights to switch to audio‑sync mode, 2) calls the launcher script to set graphics based on your profile, and 3) tells the speaker to read the stats. Use MQTT or Webhooks so every trigger goes through that hub. That way you only press one button or say “Game On” and everything falls into place. If you want extra speed, push the scene to your controller’s “macro” button, so you’re not juggling multiple apps. Give me the device list and I’ll sketch the YAML for you.
