Zhsunyco ESLs

Anyone seen Zhsunyco ESLs on aliexpress?

They look really nice (no visible barcode, nice symmetric housing), are cheaper than GICIsky, have also 3 or 4 color models.

The seller is very helpful, even sent me BLE protocol spec including auth challenge AES key.

Would be perfect if we could use something like that in Home Assistant.

I don’t understand previous post. Does that mean that their ESLs can be flashed with OpenEPaperLink firmware? Or that there is a HA BT integration for their protocol? Or that Zhsunyco uses some kind of standardized protocol that can be readily integrated into HA?

It is a bunch of search results for people who have done this before with other epaper Bluetooth shelf tags. You can either apply what they learned to your displays or use the hardware that is already working.
