These examples and documentation is based on the following versions:

• Home Assistant version 2023.12.3
• ESPHome version 2023.12.5

The config for the LilyGo T5 S3 Plus board is not available in ESPHome by default, but can be downloaded and imported into your config.

The original config can be found at: https://github.com/Xinyuan-LilyGO/LilyGo-EPD47/blob/master/platformio/boards/lilygo-t5-47-plus.json

• Install ESPHome add-on in your Home-Assistant.
• Install Advanced SSH & Web Terminal or other terminal add-on to be able to navigate through the Home-Assistant filesystem.

• In the Home-Assistant menu click on ESPHome.
• In the right top click on Secrets

wifi_ssid: "Name of your wifi"
wifi_password: "wifi password"

• In the Home-Assistant menu click on ESPHome.
• Click on New Device
• Click on Continue
• Give it a name like basic-clock
• Select ESP32-S3
• Click on Skip
• Click on Edit on the new device and save the config on your computer (you will need some config values later on)
• Copy and paste the contents of basic-clock.yaml into your device.
• Replace the REPLACE_ME values with the values from the saved config on your computer.
• Save the config, and you are ready to flash your board with the new config.

• In the Home-Assistant menu click on Terminal.
• Run mkdir -p /config/esphome/.esphome/basic-clock/boards
• Run cd /config/esphome/.esphome/basic-clock/boards
• Run wget https://raw.githubusercontent.com/Xinyuan-LilyGO/LilyGo-EPD47/master/platformio/boards/lilygo-t5-47-plus.json
• Run cd ..
• Run mkdir fonts
• Run cd fonts
• Run wget https://github.com/hprobotic/Google-Sans-Font/raw/master/GoogleSans-Bold.ttf

Now you should have the following file tree:

/config/esphome/.esphome/
|
+ basic-clock
  |
  + fonts
    |
    + GoogleSans-Bold.ttf
  + boards
    |
    + lilygo-t5-47-plus.json

We are going to use Chrome and the ESPHome web app to flash the first firmware through USB on your remote device (desktop or laptop).

The LilyGo does not need to be connected to the Home-Assistant server directly.

• In the Home-Assistant menu click on ESPHome.
• Click on the 3 dots next to Logs on your new device basic-clock
• Click on Install
• Click on Plug into this computer
• It will start building the firmware, wait on it and download the firmware to your computer.
• Chrome will see the file as insecure and you need to click on Keep to accept the file.
• Open the web application in Chrome ESPHome Web
• Be sure your board is connected with a good working USB+C cable!
• Reset your board to accept a new firmware by holding the button STR_100 and press the button REST.
• Click on Connect and select your device.
• Click on Install and select your downloaded firmware.
• When its done click on REST and it should boot your firmware.

• Click on the 3 dots next to Logs on your new device basic-clock
• Click on Install
