Hi, very new to Home Assistant.
I’m trying to install device on my esp32 through wireless. But got this error.
I have searched many same issues in Internet. I have tried built OTA web update on my esp32, write the code about connecting wifi, setting ArduinoOTA port 3232 and letting the on-board led blinking, it’s running. Even check the ESP32 IP on Advanced IP Scanner correctly. However, still not solute this problem.

This is my esphome YAML. Thanks for helping.

esphome:
  name: testdata
  platform: ESP32
  board: nodemcu-32s

# Enable logging
logger:

# Enable Home Assistant API
api:

ota:
  password: "b111dfdef449e288adf370eb372847b3"

wifi:
  ssid: "CCSPE-AP-02"
  password: "mypass"
  # use_address: 192.168.0.193

  # Enable fallback hotspot (captive portal) in case wifi connection fails
  ap:
    ssid: "Testdata Fallback Hotspot"
    password: "Cq1w1hD6cYvC"

  manual_ip:
    # Set this to the IP of the ESP
    static_ip: 192.168.0.126
    # Set this to the IP address of the router. Often ends with .1
    gateway: 192.168.0.1
    # The subnet of the network. 255.255.255.0 works for most home networks.
    subnet: 255.255.255.0
captive_portal:

This is error code.

The first flash needs to be done serial. OTA only works afterwards.

So you mean that I have to install by plug into the computer running esphome dashboard at first time?

Indeed. First time serial, only after that OTA.

If reaching the computer running ESPHome is inconvenient then you can also download the flash file (is one of the options) and use the standalone flasher: https://github.com/esphome/esphome-flasher

Same here… For me, the entire process is:

  1. Add a new device from within ESPHome
  2. Download (or Copy the content of the .yaml file
  3. Built everything using command esphome compile on your local desktop
  4. flash using esphome upload or esphome run
  5. Afterwards, try ESPHome if the device is found …
