Generates precise, board-specific ESPHome firmware configurations for ESP32 and ESP8266 microcontrollers.
This skill transforms Claude into an expert embedded systems engineer specialized in the ESPHome ecosystem. It streamlines the creation of device-level firmware by ensuring hardware-accurate GPIO mappings, sensor configurations, and communication protocols. The skill enforces a strict 'Hardware-First' workflow, requiring board confirmation before generating YAML to prevent pinout errors. It covers everything from basic sensors to advanced BLE proxies and custom displays, while strictly adhering to security best practices like credential abstraction via secrets.yaml.
