Introduction to ESPHome

ESPHome is a versatile, component-based software enabling the creation of custom firmware, primarily for ESP32 and ESP8266 devices. While it’s commonly used for temperature and humidity sensors, its capabilities extend to many, many sensor types, including Bluetooth Proxies, enhancing Home Assistant’s functionality to BLE devices.

Installing ESPHome Add-On

The installation process involves accessing the add-on store in Home Assistant, locating the ESPHome add-on, and initiating the installation. Once installed, the left-hand menu in Home Assistant facilitates navigation to ESPHome and device addition.

Setting Up Your First ESPHome Device

Initiating a new device involves creating a configuration and selecting device type (e.g., ESP8266, ESP32). The setup includes defining Wi-Fi credentials, building your YAML configuration, and firmware installation.

Integration with Home Assistant

Once the ESPHome device is set up, it automatically integrates with Home Assistant. Configurations and entities become accessible within Home Assistant, enabling easy automation.

Practical Examples: Touch Button & PIR Sensor

I go through configuring a capacitive touch button and a PIR sensor within ESPHome. The setup process includes wiring, code amendments, and integration within Home Assistant.
