I got a reTerminal E1002 and thought I’d share my dashboard and ESPHome code. I also have a XIAO 7.5" ePaper Display and was able to use a lot of the code from that project.
The E100x displays have a much better build (metal case) with programmable buttons, MicroSD card support, leds and buzzer. It also has battery status which was my biggest issue with the XIAO 7.5".
The biggest con to the E1002 (color version) is that the refresh takes a long time (sometimes 30 secs) because it looks like it flashes every color for every element. It flashes like crazy while doing the refresh. I don’t have and numbers yet, but it looks like the battery life is less that the B&W epaper. I’ll update this topic when I have a rough number of days.
I’m still messing with the colors. Haven’t settled on what works best yet.
