What

The SHA2017 Badge is an awesome piece of hardware based on a ESP32 and an e-ink screen. It can run Micropython and a ton of apps for that are available @ the Hatchery. While I was thinking about writing an app for controlling Home Assistant, I realized that ESPHome would be very suited for that. So here are some pointers to running ESPHome on the SHA2017 Badge.

How to install

I am assuming some familiarity with ESPHome at this point. If not, check the guides on the ESPHome site: https://esphome.io/guides/getting_started_command_line.html or https://esphome.io/guides/getting_started_hassio.html

• Compile firmware using a yaml config file suited for your needs (a working one can be found here).
• Upload it to the badge through USB (I used esphome-flasher since I got errors trying uploading with esphome cli and I am too stupid to use esptool :p).

If you enabled wifi and OTA and everything went well, you can program it wirelessly next time.

Stuff that is working

• Touch pads (through MPR121)
• USB and battery voltage readings (not verified but they seem sane)
• Button marked flash on the back

Todo

• Support for the DKE Group DEPG0290B1 E-Ink screen.

Unfortunately the screen is not supported in ESPHome. There is a Waveshare E-Paper Display Component, but it looks like this does not work with our screen. Maybe we can use this as a base for our own component.
