> paperd.ink has a 4.2” e-paper display If your target market is the whole world, please also provide dimensions using the metric system. For most of the world, inches don't mean anything. 4.2” is approx. 10.7 cm.

I'm a staunch metric supporter, but to be fair I have never encountered a country that measures screens as anything other than inches.

Many places in europe have legal requirements about using national standard units. In Slovenia for example, you'll always see both inch and cm diagonal measurements for screens (with W×H usually only in cm).

This, but then somehow (close to) plug an play with Home Assistant... That would be very cool. I guess, since it is a development board, I just have to wait for someone to do it (or wait until my own retirement to find the time ;))

I think you will find libraries for that on the esp32 that this uses are already available.

(OP here) Update: We sold out the first batch of paperd.ink! Thanks to each one of our supporters, we managed to pull this off because of you. As next step, we would love to talk with the users once they have paperd.ink in their hands. And for those who missed out, you can drop your emails or keep a track of our social media to be updated. Thanks again! PS: I will reply to the pending comments shortly. Sorry things h…

Hey, I can't see it on your page, what's your selling price?

I am selling a very similar programmable display for $169, but it has a bigger screen and a wooden frame:

I suspect your price point is much lower than mine?

Why this instead of eg. M5Paper [0]? Similar price, been thinking to buy something like that, but delaying the decision, hoping PineNote[1] comes out soon :D [0] https://shop.m5stack.com/collections/m5stack-new-arrival/pro... [1] https://www.pine64.org/pinenote/

I will just shamelessly add to the list this wooden 7.5 inch display that I have been working on over the past two years:

Price-wise it's in between the M5Paper and the PineNote, but personally I think it's the best-looking one for the smart display use case. :P

Also, since this is HN, I'd like to mention that I am looking for collaborators/co-founders to work with me on this project. You can contact me at mail@konstantinschubert.com

Being ESP32-based should make it trivially easy to use with ESPHome[0] in Home Assistant. I use ESPHome + HA with countless M5Stack ESP32 units.
