Getting it up and running

Tuya Convert

This bulb is a Tuya device, so you’ll need to use tuya-convert to initially get ESPHome onto it. After that, you can use ESPHome’s OTA functionality to make any changes.

  • Put the bulb into “smartconfig” / “autoconfig” / pairing mode by switching the bulb off and on 4 or 5 times in a row in quick succession.
  • The bulb blinks white rapidly to confirm that it has entered pairing mode.

Remember to make the following changes to the example YAML config below:

  • line 6: Give your device a name.
  • line 7: Give an ID name, all lower case and change spaces to underscores.
  • line 10: Set up the static ip for your device that matches to your environment. Remember this IP must be unique in your LAN.
  • lines 26, 27 and 28: gateway is the IP of your router, subnet most certainly and dns1 again the IP of your router.
  • line 31: This is only if a red cross appears here. AP SSIDs can only contain up to 32 symbols. If you’ve chosen a long device name it might exceed. Either shorten the device name or delete right after AP, “ (”.
  • line 32: You’ll probably don’t want to complicate your live with a WiFi password when your bulb enters access point mode. Feel free to change from password: ‘1234abcd’ to password: ‘’.

Once you’ve completed the tuya-convert process and flashed ESPHome, you can integrate your bulb in Home Assistant using a lovelace Light card.

Enjoy your hard work and impress some people with the magic 8-]
