Home Assistant Dashboard

Create a Home Assistant Dashboard you want to display. I recommend using the kiosk-mode, card-mod and layout-card plugins to customize and tune the dashboard for your display.

Setup sibbl's hass-lovelace-kindle-screensaver program to regularly screenshot the desired dashboards for the HomePlate.

More information in hass.md.

Inkplate

Install PlatformIO. Then copy src/config_example.h to src/config.h and enter your settings, and build & run with:

pio run

The first flash/installation needs to be done over USB. Future updates can be done over USB or WiFi with:

pio run -e ota

To monitor serial output without re-flashing:

pio device monitor

Updating

git pull
platformio upgrade
platformio platform update
platformio lib update

Debugging

If you get the following error while booting your inkplate, run the Inkplate_Wavefrom_EEPROM_Programming example to update your Inkplate's waveform.

Wavefrom load failed! Upload new waveform in EEPROM. Using default waveform.

Older Inkplates don't appear to ship with an updated waveform. I found waveform 3 looks the best for mine.
