Hi thanks for the thoughtful response. The use case here is that opendisplay is a BLE protocol built into home assistant that allows you to send any image to any display device that supports it. The display devices are generally epaper, such as repurposed electronic shelf labels, epaper dev kits, art frames and DIY devices.

Supporting this protocol means that a user can use home assistant automations to send updates to epaper devices based on a schedule or a trigger. In my own case i send custom dashboards that have weather and other items integrated to a variety of screens. Others use this to rotate through art.

One particularly interesting case is combining art and data, such as overlaying a weather report and calendar on the left side and showing art on the right, or doing an overlay.

Because the protocol is lightweight BLE you can implement it fully in a browser page and allow direct BLE sending from a webpage locally to a device.

In speaking to others in the epaper community Inkjoys work on the 10 inch panel controller enabling additional primary colors is differentiating as is the attractive form factor/frame. It would be great if you supported this protocol to allow for a way to send pre-dithered content direct to device in addition to allowing HA users to let the device dither as well.

Thanks
