Will this skill modify my secrets.yaml file?

No. To protect your security, the skill will never read or modify your secrets.yaml file. It will only use !secret references in the generated YAML.

Can I use this for Home Assistant automations?

No, this skill is dedicated to device-level firmware (what runs on the chip). For automations that run within Home Assistant, use the home-assistant or node-red skills.

Does it support commercial products like Shelly or Sonoff?

Yes, it includes reference guides for converting and configuring popular commercial smart home devices that use ESP chips.

Why does the skill ask for my board type every time?

This is the 'Iron Law' of ESPHome. Different ESP32/ESP8266 variants have different pinouts and strapping pins; confirming the board prevents hardware errors or boot loops.

Productivity & Workflow

Generates precise, board-specific ESPHome firmware configurations for ESP32 and ESP8266 microcontrollers.

About

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.

Key Features

Mandatory hardware verification to ensure correct GPIO and board-specific mapping
Specialized templates for ESP32-S3, C3, C6, and legacy ESP8266 variants
Integrated troubleshooting and calibration patterns for noisy hardware data
Support for 200+ sensors, binary sensors, displays, and climate components
14 GitHub stars
Security-first configuration using !secret references for all credentials

Use Cases

Setting up BLE Proxy and Bluetooth tracking for Home Assistant integration
Creating custom firmware for commercial devices like Shelly or Sonoff switches
Configuring a multi-sensor environmental monitor on an ESP32-S3 board
