Getting Started with ESPHome

Today we will be taking a look at setting up your first ESPhome device in Home Assistant.

Introduction

“ESPHome is a tool which aims to make managing your ESP boards as simple as possible. It reads in a YAML configuration file and creates custom firmware which it installs on your ESP device. Devices or sensors added in ESPHome’s configuration will automatically show up in Home Assistant’s UI.“

Things needed

1. ESP8266 or ESP32 Device
2. Power supply to power the ESP 3.3v/USB
3. USB Data cable (since we will be using a esp board that has a usb port) or usb to TTL
4. Home Assistant with Esphome addon Installed
5. Sensor module/s in this guide we will be using a relay and a DHT11 temperature and humidity sensors.
6. Jumper/dupont cables depending on how you will be connecting the devices together

Secrets file code used.

Currently in my secrets file I have only added my wifi credentials this is to simplify setup of future devices and we will be discussing this more in the future.

wifi_ssid: "YourWifiNetowkname"
wifi_password: "YourWifiPassord"

Code for single relay

Remember to confirm you are using the correct GPIO pin.

switch:
  - platform: gpio
    pin: GPIO05
    inverted: true
    name: "Relay"

If you are using a different relay and the on/off switch is inverted you can change the option “Inverted” to “false” instead of true.

Code For DHT11

sensor:
  - platform: dht
    pin: GPIO04
    temperature:
      name: "DHT Temp"
    humidity:
      name: "DHT Humidity"
    update_interval: 10s
