Verified steps

  1. Add an ota: block with platform: esphome to the device's YAML configuration
  2. Set a unique password per device under the ota block, or migrate to api: encryption: key: for the newer encrypted API channel - these are distinct, non-interchangeable mechanisms
  3. Note the default OTA port varies by chip family
  4. Trigger an OTA push with esphome run <file>.yaml or esphome upload --device <ip> from the CLI or Dashboard
  5. If mDNS discovery fails to find the device, pass its IP explicitly with --device
  6. Use a unique OTA password/API key per device rather than reusing one across the fleet
