Let your Grok Bot control lights, buttons and sensors you build. Open source.
Status: one ESP32-S3/OLED kit passed USB and Wi-Fi acceptance; native Grok Bot MCP calls remain unverified (project status). Independent project, not affiliated with SpaceXSI.
Pick a path:
Already use Home Assistant? Check what it offers with the read-only probe.
The first physical experiment uses the tested ESP32-S3 and OLED kit. The owner's board passed USB and Wi-Fi acceptance, and an approved Grok Bot local command showed text on it. Follow the repeatable kit guide. Another person's reproduction is still needed.

Grok Bot normally runs on its cloud computer. This does not expose your home network. On 12 October, the owner's Grok Bot ran approved gateway commands on the Mac. Gateway logs matched the commands, including a display command to the physical OLED. This is a verified local command route. Grok Bot did not call the gateway's MCP tools natively. A Mac-to-Pi route through SSH remains an untested possibility.
The gateway's local serve works on loopback today. The owner's Grok Bot used an
approved local command (ADR 004). Packaged
remote MCP and native Grok Bot tool calls remain unverified. A tunnel adds reachability, not authentication.
