# ESPHome Devices Reference skill for ESPHome device configuration and firmware. ## Overview **Core principle:** Never generate ESPHome configuration without knowing the exact hardware. Board selection determines GPIO mapping, flash size, available features, and component compatibility. **Context:** This skill requires hardware confirmation before any YAML generation. Different ESP chips have vastly different capabilities - ESP32-S3 supports USB and cameras, ESP32-C6 supports Thread/Matter/WiFi 6, ESP32-H2 is BLE+Thread only (no WiFi), ESP32-P4 is high-performance with MIPI DSI displays, and ESP8266 has limited GPIO and memory. ESPHome also supports nRF52 (Zephyr), RP2040, and LibreTiny (BK72xx/RTL87xx) platforms. ## The Iron Law ``` CONFIRM BOARD BEFORE GENERATING ANY CONFIGURATION ``` ESP32 has 12+ variants with different GPIO mappings, strapping pins, and capabilities. Assuming `esp32dev` when the user has an S3, C3, or C6 produces configs that silently fail. Always get explicit board confirmation first. ## The Process ``` User request │ ▼ Ask: What board? │ ▼ Board confirmed? ──no──▶ Ask again │ yes ▼ Battery/actuator/outdoor/>5V? ──yes──▶ Vera: Hardware Safety Review │ no (or cleared by Vera) │ blocks if critical risk found ▼ ▼ Ask: Output method? ◀── safety cleared │ ▼ deep_sleep / battery / solar / power bank? ──yes──▶ Flag Watt for power budget │ no (or ...
