Controlling an air-gapped vacuum from Home Assistant via text to speech

It gets control of an offline robot by doing something almost obvious in hindsight: play the robot's own wake-word + command audio from a nearby Pi, triggered by Home Assistant POSTs. That avoids rooting/Valetudo and keeps firmware intact, while the repo packages Docker, Ansible and embedded Piper TTS for a near plug-and-play hack — though reliability hinges on speaker placement, timing and device-specific command sets.
