Hermes Gadget：语音交互设备 SDK

Build voice and text devices for your Hermes Agent, with ESP32 firmware, a Linux client, and a desktop simulator.

Hermes Gadget Hold a button. Ask Hermes. Hear the answer. A small device for your own Hermes Agent, with its tools, memory, and skills. Set up a board · Try the simulator · Read the docs The desktop simulator runs the same device core. No board needed to try it. Choose your starting point I have a board I want to try it first I want to build with it Open the browser installer Start the desktop simulator Explore the SDK Install over USB, connect Wi-Fi, and pair with your Hermes. Try a scripted demo, then connect your own Hermes. Add a board, device actions, sensors, or your own face. Chrome or Edge, a USB data cable, 2.4 GHz Wi-Fi, and Hermes. No firmware toolchain. Python 3.10+, CMake 3.16+, and a C++17 compiler. Start with the development guide and tests. What you can do Talk and listen. Hold TALK to speak, release to send, and hear your Hermes reply. See what is happening. Read replies, answer confirmation questions, and receive cards from your agent. Let Hermes act. Expose the gadget's LEDs, sensors, and other controls as agent tools. Your Hermes does the thinking. Real conversations need Hermes Agent and the Gadget plugin. Voice also needs speech recognition and text-to-speech configured. The demo server gives scripted replies. Follow Connect Hermes when you are ready. Supported hardware Hermes Gadget runs on ESP32-S3 boards and Raspberry Pi 4/5, with a desktop simulator for trying it without hardware. See Supported hardware to compare boards, controls, audio, and setup options. Hardware ports remain experimental until a complete physical verification report is recorded for the exact revision. Check the verification table before choosing a board. Try the demo from a checkout Already have Python, CMake, and a compiler? Start here. In your activated environment at the repository root: python -m pip install -e ".[dev]" hermes-gadget build-sim --test hermes-gadget devserver --pairing In a second terminal with the same environment activated: hermes-gadget sim --url ws://127.0.0.1:8765/gadget --board sim-466x466-round Type approve <CODE> in the first terminal, using the code on the device. Type a message in the simulator to receive a streamed echo. The desktop guide covers platform-specific prerequisites and live audio. On the screen Ready Listening Thinking Speaking These images show the simulator's device display. The simulator guide covers its desktop controls, board profiles, and scripted runs.

Releases include prebuilt firmware for the profiles listed in that release. Newly merged profiles need a source build until the next release. After the first USB flash, hermes gadget update installs new firmware over the air. A build that cannot reach Hermes rolls itself back. The simulator and firmware share a portable C++17 core. CI tests the core, Python tools, installer, and plugin against a real Hermes gateway, and builds every supported board. The development guide describes the test suites and pinned Hermes version. After installing firmware, you can configure Wi-Fi from your phone through the gadget's temporary network. USB setup remains available. Wake-word activation is not included. The Home Assistant and MQTT examples expose a configured lamp and temperature sensor through a Linux gadget. They include pairing instructions, fixed action targets, asynchronous completion and local integration tests. Contributing Bug reports from real boards, new boards, fixes, and docs are welcome.
