  # As of the publication of this guide, ESPHome Dashboard only seems to use the "name" of the device for mDNS lookups.
  # This causes ESPHome Dashboard's DNS lookups to fail to resolve correctly, resulting in its failure to connect to your device.
  # If you want to add the mac_suffix to the device name, consider adding it to the "name" value in the "substitutions" section.
  # If you still want to enable the "name_add_mac_suffix" option, consider using the "manual_ip" option in the "wifi" section below so ESPHome Dashboard can find your device on the network.
