ESPHome Config Helper

Generate and troubleshoot ESPHome configurations for ESP32 and ESP8266 devices. Ready-to-use YAML templates, GPIO pin-assignment guidance, sensor and actuator setup, WiFi and OTA config, plus fixes for common compile and connection errors.

This skill speeds up building smart-home firmware with ESPHome. It generates validated YAML for ESP32/ESP8266 boards, assigns GPIO pins without conflicts, wires up sensors and actuators, configures WiFi and OTA updates, and troubleshoots errors like 'Unknown platform', 'GPIO already in use', 'Could not compile', and WiFi connection failures — turning device ideas into flashable configs fast.

When to use

Use when creating an ESPHome config, setting up an ESP32/ESP8266 device, adding sensors or actuators, configuring WiFi or OTA updates, assigning GPIO pins, or fixing ESPHome compile and connection errors.

Examples

Sensor node config

Generate ESPHome YAML for a device

Create an ESPHome config for an ESP32 that reads a BME280 over I2C and a PIR motion sensor, exposes them to Home Assistant, and enables OTA updates

Fix a GPIO conflict

Resolve a compile error

My ESPHome build fails with 'GPIO already in use' — review this YAML and reassign the pins so the relay and DHT22 don't clash

WiFi + fallback hotspot

Robust connectivity setup

Add WiFi config to my ESPHome device with a fallback access point and captive portal so I can recover it if the network changes
