Hey,
I’m not sure if I’ll have time to work on this project, but I found a cool way to use electronic price tags, especially with home assistant.
My main goal is to share it with you and hear from those who might be interested in trying it out…

Hi,
Checkout OpenEpaperLink.de, there is a HA integration to that 
I use it to display electricity prices, weather etc etc.

Thanks, I will check this.
after further investigation, seems really hard work to achieve…
Do you have a link to a compatible tag? AliExpress, eBay or similar?

Works greater with OpenEpaperLink flashed to ESP32-S3 (https://pl.aliexpress.com/item/1005006446406795.html)
The Home Assistant integration also Just Works
