Adding an ESP32‐C5 into ESPHome

ESPHome fully supports the later ESP32-C5, which is great as it gives you both 2.4GHz and 5GHz Wi-Fi.

ESP-IDF framework

As the ESP32-C5 relies on the ESP-IDF framework, you need to configure the device within the YAML file.

An example is shown below.

esphome:
  name: your-esp32-c5-name
  friendly_name: Your ESP32-C5

esp32:
  board: esp32-c5-devkitc-1
  variant: esp32c5
  framework:
    type: esp-idf

# Enable Home Assistant API
api:
  encryption:
    key: "YOUR_API_KEY_HERE"

wifi:
  ssid: "YOUR_SSID"
  password: "YOUR_PASSWORD"
  # Optional: For dual-band, if you want to force 5GHz specifically
  band_mode: 5GHZ

Creating a new ESP32-C5 Device

As ESPHome does not currently list the ESP32-C5 within its supported MCUs, you can simply select another and then once the YAML basic file is created, you can update as shown above.

For example, selecting ESP32-C6 will create with the YAML file:

esp32:
board: esp32-c6-devkitc-1
  framework:
    type: esp-idf

So you can then simply edit this to:

esp32:
  board: esp32-c5-devkitc-1
  variant: esp32c5
  framework:
    type: esp-idf
