Bring Your Own Speakers

Use What You Own

Already have speakers you love sitting unused? HouseWaves-Legacy brings them online. Connect almost any passive bookshelf, in-wall, or vintage speaker to Home Assistant — there's no need to replace gear that already sounds great.

Mounts Anywhere

Fasten the module to the back of your speaker with screws, stick it on with the adhesive strip, or simply rest it on the floor nearby. Whatever fits your setup, the compact enclosure stays out of sight and out of the way.

Ready in Minutes

Wire in your speaker, power the module with a 24V DC adapter, and join your Wi-Fi. In under three minutes you're streaming music and TTS announcements through the speakers you already own — fully synchronized across every room.

Engineered for Home Assistant

Open Hardware

Built on a unified ESP32 controller that changes the rules of smart home audio. Our platform merges a dual-core MCU, a premium I2S DAC and a high-efficiency Class-D amplifier with high-speed PSRAM to manage complex audio streams and flawlessly deliver clean, accurate audio.

Open Firmware

Built for ESPHome and ships with SendSpin firmware for perfectly synchronized multi-room audio. Fully compatible with any available ESP32-based firmware including Squeezelite, Snapcast, AirPlay2. Your speakers. Your choice. Stay flexible and current as the Home Assistant ecosystem evolves, without any hardware changes. No proprietary apps or cloud lock-ins.
