Flash an ESP32 and build a Home Assistant panel through MCP (French video)

Bricolo2.0 shows how to connect Arduino CLI and Home Assistant to an AI agent through the arduino-mcp and ha-mcp servers, in French. He connects both servers to Antigravity and opencode. In the 16-minute video the agent writes and flashes an ESP32 project and builds a Home Assistant control panel, which he compares with the manual method.

Briefing

Setup is on Windows. Arduino CLI comes from winget, and the ESP32 core is added through Espressif's board manager URL. Both MCP servers run through uvx, so uv is installed first with its PowerShell script; the Home Assistant server takes the instance URL and an access token. The description lists every command and both config files.

The video opens by setting Arduino CLI against ESPHome as two ways to program the board. The first flash by the agent starts at 7:40, and the ESPHome automation at 10:35. Bricolo2.0 published it on 12 June 2026, and it runs 15:49.
