I have been using Home Assistant and ESPHome for almost 2 years now and automated a lot of trivial stuff around my house.
I love these projects and rely on them day by day. There are many custom projects that I have made until now for my personal use and in all of them I used the information shared by this community, so I decided to give something back and share this project, hoping that it will be interesting and helpful for somebody else.
Project Description
As mentioned in the title, this project is a Lilygo T5 Plus based informer, designed to display some useful information from Home Assistant using the power of ESPHome.
It contains all the relevant information that I needed to make it work, and by “work” I mean to get it compiled, uploaded and displaying the right information for me.
It was tricky sometimes because of the esp32-s3 chip. Due to this, there were some difficulties at compilation in ESPHome, but I managed to do it in the end.
Below is a photo of the end result that I have obtained.
Hi,
Is this still working for you with the latest ESPHome version for HA?
I get the error: Configuration does not match the platform of the connected device. Expected an ESP32 device.
I have the latest 2024.11.2 ESPHome Device Compiler installed as Add on in my system and I have just tested compiling the software for this project.
The program was compiled without any issue.
I don’t have a .esphome folder within my esphome main folder, so I created all the directories manually, Config/esphome/.esphome/build//boards/ and placed the lilygo-t5-47-plus.json file there. Trying to compile with the Esphome dev compiler (v2024.12.0-dev), and getting ‘UnknownBoard: Unknown board ID ‘lilygo-t5-47-plus’’
Can you help? Esphome is installed as an addon within my HA.
So the .esphome folder inside the esphome main folder exists when you are running ESPHome as a standalone container. If you run it as HASS Add On, it is a little bit different.
For this scenario you will need access to the OS, via ssh.
When you are logged in to the machine running your Home assistant, you should go to the directory /mnt/data/supervisor/addons/data/<add on container name (ending with _esphome)>/build/<your device name>/boards and place the .json file here.
For example, the “boards” path for me looks like this /mnt/data/supervisor/addons/data/5c53de3b_esphome/build/esphome-web-9e3bd4/boards.
After this it should find the board when you try to compile it.
Finally. Getting root access to HAOS was not, that easy.
After successfully coping lilygo-t5-47-plus.json to “boards”, I received another compiling error:
from .piolibdeps/esp32-paper/SensorLib/src/bosch/BoschParse.cpp:30:

I solved it with “root” access again and renamed the affected files:
(they can be found in one of the subfolders of /mnt/data/supervisor/addons/data/5c53de3b_esphome/build/esp32-paper/.piolibdeps/
