Any chance there is a way to get it to work with this,

I dont think it would be too difficult.

This is the epaper driver library used for this project. The 7.3 7-color appears to be supported.

I dont have that panel so i can't test it, but if you get it working then feel free to open a pull request and we can merge it into the main project.

If you want I can provide a branch that might work for that display and you can test it and let me know if it works. Let me know if you're interested.

[mendip-defender]

Yes, please. I will give it a go. I'm a tinker of code, not a coder but I like the project after spotting it on Hackaday.

Try this branch....
https://github.com/lmarzen/esp32-weather-epd/tree/43-waveshare-73inch-acep-7-color-e-paper-e-ink-display-module

make sure to set the correct panel in config.h

[lmarzen]

Let me know how it goes

[mendip-defender]

So it works, just only part of the screen shows up.

[lmarzen]

Okay, that's promising.

I did read more into the epaper driver library source code and for some displays you need to explicitly set it to paged mode.

I pushed some changes try again, and let me know how it goes.

Bwhahahah I think you have cracked it. When I get a chance I will look to make 7 colour versions of the icons.

EDIT: Don't worry about the BME, for some reason the BME I have connected doesn't work. It does work with another I have on my Pi.

WOOOAAAHH!! success! Ill merge the changes into main.

Multi-colored icons would be a super neat addition as well!
