Product Q&A

Q:Does this module require a Home Assistant server to function?

Yes. This module is specifically designed as a satellite device for Home Assistant. It requires an active Home Assistant instance on your local network to process voice commands and control your smart home devices.

Q:How does the physical mute switch protect my privacy?

The hardware mute switch physically cuts off the power supply to the dual microphones. When muted, the microphones are completely disabled, ensuring that no audio is captured or transmitted under any circumstances.

Q:Do I need to assemble or flash the firmware myself?

No. The module comes pre-flashed with ESPHome firmware and is ready to use out of the box. You simply need to power it via USB-C and follow the quick pairing process in your Home Assistant dashboard.
