Lilygo T-display YAML code

ESPHome
1

Does anyone has a very simple working YAML code to start with Lilygo T-display.
I received my unit and I would like to load, using Esphome, a very basic code to start learning.
For example a code that would display a Home Assistant entity and that I can turn ON/Off using the button on the device.

there are a bunch of different versionā€¦ T-Display S3, T-Display-s3-OLED. For the plain T-Display, here is mine to get you started:

Thank you very much, this look very good to get me started

Iā€™ve been trying to figure out how to load above code into my ESP32 to get started with ESPhome and Home assistant but searching has not helped as to how to go about it.

Iā€™m successfully running Home Assistant in Docker. ESPHome has been installed and ESP32 connects and Iā€™m able to able to ā€œPREPARE DEVICE FOR FIRST USEā€ in web interface then successfully ā€œConfigure Wi-Fiā€. After this, Home Assistant notifies me of new device which then I configure and everything seems to work fine. But after this I have no clue as to where to go from here for custom code like the one above. Can someone please point me in the right direction. I been at this for days and just canā€™t figure it out.

It should be visible in the ESP-Home addon of Home Assistant.
Do you have that installed?

I gave up running HA in Docker. This was causing me all sorts of issues due to software limitations. Iā€™m running it in a virtual machine now and ESPHome works as it should.
