Sharing ESPHome devices

We have added configuration options to ESPHome to make it easier to create, configure, install and distribute devices running ESPHome.

No part of a “template” configuration should have any references to secrets, or have passwords pre-applied. ESPHome makes it easy for the end-user to add these themselves after they adopt the device into their own ESPHome dashboard.

Example configuration

# These substitutions allow the end user to override certain values
substitutions:
  name: "project-template"
  friendly_name: "Project Template"

esphome:
  name: "${name}"
  # Friendly names are used where appropriate in Home Assistant
  friendly_name: "${friendly_name}"
  # Automatically add the mac address to the name
  # so you can use a single firmware for all devices
  name_add_mac_suffix: true

  # This will allow for (future) project identification,
  # configuration and updates.
  project:
    name: esphome.project-template
    version: "1.0"

# To be able to get logs from the device via serial and api.
logger:

# API is a requirement of the dashboard import.
api:

# OTA is required for Over-the-Air updating
ota:
  platform: esphome

# This should point to the public location of this yaml file.
dashboard_import:
  package_import_url: github://esphome/esphome-project-template/project-template-esp32.yaml@v6
  import_full_config: false # or true

wifi:
  # Set up a wifi access point
  ap:
    password: "12345678"

# In combination with the `ap` this allows the user
# to provision wifi credentials to the device.
captive_portal:

# Sets up Bluetooth LE (Only on ESP32) to allow the user
# to provision wifi credentials to the device.
esp32_improv:
  authorizer: none

# Sets up the improv via serial client for Wi-Fi provisioning
improv_serial:
  next_url: https://example.com/project-template/manual?ip={{ip_address}}&name={{device_name}}&version={{esphome_version}}

name_add_mac_suffix - Adding the MAC address as a suffix to the device name
project - Project information
esp32_improv - Esp32 Improv
captive_portal - Captive Portal
wifi -> ap allows you to flash a device that will not contain any credentials and they must be set by the user via either the ap + captive_portal or the esp32_improv / improv_serial components.
dashboard_import

NOTE

The Project information above is required for adoption to work in the Dashboard.
- package_import_url - This should point to the public repository containing the configuration for the device so that the user’s ESPHome dashboard can autodetect this device and create a minimal YAML using Remote/Git Packages.
- import_full_config - This signals if ESPHome should download the entire YAML file as the user’s config YAML instead of referencing the package. Set this to true if you are creating a tutorial to let users easily tweak the whole configuration or be able to uncomment follow-up tutorial steps.
improv_serial - Improv Serial
