Text Not Centering Correctly on LilyGo T5 4.7

ESPHome
1

I’m setting up my new LilyGo T5 4.7 in e-ink display but am having issues with my centered text aligning to the right edge of the screen instead of the actual center. I’m new to ESPHome and would greatly appreciate any assistance.

Here’s what I’m seeing:

Here’s my YAML:

Is something going on with your screen rotation perhaps? What happens if you do this?

rotation: 90

I tried that, and it simply made things display in portrait vs. landscape mode. I was able to solve my own problem, though! I realized the text was essentially centering around the x coordinate, so I adjusted the x-axis location to be half the screen width, and that solved the problem!

So instead of this:

it.print(10, 150, id(font_med), TextAlign::CENTER, "Current Status");

I changed the x-axis coordinate to this:

it.print(480, 150, id(font_med), TextAlign::CENTER, "Current Status");

Since the width of the screen is 960, the text now centers along the center of the screen!

I’m having a problem with the external component: github://ashald/esphome@lilygo-t5-47

I think it has been removed from github. Do you have the same issue? Have you found any solution?
Thank you!!

You haven’t said what your issue is, so who can say?

Is unhelpful.

And it still seems to be there

I fully agree, Nick. Thank you for providing the Link.
The display is up and running at the moment, but I cannot update after updating ESPHome to 2023.12.

There seems to be a problem with the external component:
…

external_components:
  - source: github://ashald/esphome/components@lilygo-t5-47
    components:
      - lilygo_t5_47

…

display:
  - platform: lilygo_t5_47
    id: t5_display
    rotation: 0
    update_interval: 2min
    
    lambda: |-
      // it.filled_circle(319, 0, 40);

When I try to update, I get an error message.

I struck that. Something changed in 2023.12 ESPHome 2023.12.0 - 20th December 2023 — ESPHome

With the component I was dealing with a fix had been included in esphome and the external component was no longer needed, so I avoided the problem.
