A local voice assistant and touch dashboard for the M5Stack Tab5
A non-developer used AI tools including Claude to write all the ESPHome YAML and C++ for a wall panel with an on-device wake word on the ESP32-P4.
The full story
The owner, who is not a developer, wanted a responsive wall-mounted touch panel and local voice assistant for Home Assistant. Using only AI tools, Claude among them alongside Gemini and Antigravity, they had all the YAML, C++ snippets and automation scripts written for an M5Stack Tab5 running ESPHome and LVGL.
The wake word runs locally on the device so no audio leaves it until it hears "Ok Nabu", the microphone icon changes colour with the assistant's state, and a custom boot sequence delays the amplifier to stop a crackle from the speaker. The frame buffer sits in the board's PSRAM to keep the graphics smooth.
