Yeah, thanks! It’s great, but how could I miss that all so far…? 
Hello to all,
I’m having an issue with my e-paper display. I’m using the 2.7" Waveshare E-paper hat compatible with a Pi. The back is marked rev2.2. 264x176, 2.7inch E-Ink display HAT for Raspberry Pi, SPI interface | WF10190CZ22
I can display text just fine. However, the text and the alignment (default Left) are mirrored for some reason. I can’t seem to find a mirror option in display component or waveshare driver components.
display:
- platform: waveshare_epaper
id: eink_display
cs_pin: GPIO15
dc_pin: GPIO13
# busy_pin: D4
reset_pin: GPIO12
model: 2.70inv2
update_interval: never
# rotation: 90
lambda: |-
it.printf(65, 10, id(font1), TextAlign::TOP_LEFT, "%s", "4 juli 2024");
Any ideas?
Edit: attached a picture, it says more than a thousand words 
Edit: My other display (a larger 7.5" v3) works just fine with the same lambda… 
Have you tried to set a value for the rotation?
In your config it seems to be commented out.
Thanks for the guide, this is my version and so for its working great!
I have one issue through, and its the power. Now I´m powering it witha Power bank hidden behind the frame. It works, but after some 12-15 hourers the power bank stop to output power (but it isn´t empty). If reconnect the cord to the power bank it start to work again.
Anyone have a solution for this?

Hi!
I’m struggling with my own e-ink D. version.
I’m able to display text, but only FIXED text; each time I try to show a variable, text sensor for example, it doesn’t appear.

Variables eink_forecasted_condition, eink_forecasted_temperature, eink_portone_status are not shown, neither as icon or text.
(homeassistant_time).now() is the only variable that actually is shown.
These sensors work properly in HA dashboard.
I’m clearly using wrong some home assistant basics sensor configuration.
If some one can help on my issue I’ll very appreciate!
Would you be comfortable sharing your code? This looks excellent…!
