E-paper display

fredrike · November 12, 2019, 8:05pm

I’ve been really busy with long days and way too much Factorio (factorio.com) but here is a dump of my esphome based nodes: https://github.com/fredrike/esphome-nodes I’ve added the package-display_node.yaml which is a package file to be used on the homeassistant side. I believe contains everything from the homeassistant side needed to get the display node to work, let me know if something is missing.

Edit: Here is my updated display. The black blob is moonphase and the energy readings at the bottom is from an ESP Sparsnäs and an IoTaWatt.

Just wanted to show mine!
Thank you @fredrike for your code. Will post mine later

@makai, could you share your code?

Alexandru_Cruceanu · June 3, 2020, 8:38pm

I have replicated your project, but on a 2.9 inch Waveshare display.

Where do you guys buy these eink displays? Last time I checked they were incredibly expensive for their resolution and size.

makai · June 3, 2020, 9:39pm

Bought mine on AliExpress. Yes it’s a bit expensive, 25€ for a 4.2".

Mine is attached to a Lolin D32, SDS011 (Air Quality), a BME280 (Temp, Humidity and Pressure), a buzzer and a LED (for notification). More info here: Air Quality Sensors + E-Ink Display using ESPHome

Done here: Air Quality Sensors + E-Ink Display using ESPHome

Sorry for the delay

Hi Makai,
I have the same display ?

Hi Twinsen68!

Click on the link in the post just above yours

Bonne lecture

Sorry i didn’t read all the post

Started mine yesterday. Need something to put the board in. But for now I like the look.

bjornb · October 14, 2020, 8:51pm

I’ve found it already on aliexpress. Didn’t know they sold the cases separately.

Would you mind sharing your esp home code for your display setup? Thanks!

bernhard · October 15, 2020, 4:55pm

The case looks nice. Can you share a link?

Hey @Alexandru_Cruceanu, can you please share your YAML or a link to your github repo? I have a 2.7 inch ePaper display and thought it’d be easier to modify your code rather than starting from the bigger displays.

Thanks!

Alexandru_Cruceanu · October 16, 2020, 8:41am

Hi @LUNZ.
Sorry, but i had to rebuild my Home Assistant Setup and i have lost all my ESPHOME config.
I hope to rewrite it as soon as possible and i’ll post the yaml here.
Thanks.

LUNZ · October 16, 2020, 6:49pm

thanks for the quick response @Alexandru_Cruceanu! I’m looking forward to your post!

@fredrike thanks for linking your code! it really helped me figure it out with my specific device. I’m using an Oracle Code Card badge I got at a conference. It has a 2.7 inch screen.

I’ve posted my code here:

gist.github.com

https://gist.github.com/michaellunzer/37f29462ee9a17f22978e672c59e440c

codecard3.yaml

esphome:
  name: codecard3
  platform: ESP8266
  board: esp12e
  # on_boot:
  #     - output.turn_off: onboard_led

wifi:
  ssid: !secret wifi_ssid
  password: !secret wifi_password

This file has been truncated. show original

Two questions:

The moon_tpl sensor is not automatically rendering a value. When I set a value in Home Assistant’s Developer Tools, the moon icon displays on the screen. Also, the sensor.moon is working and returning “waxing crescent” etc.
The high/low temperatures on the forecast (on the right hand side) is not displaying but the days of the week and weather icons are.

Do you have any suggestions for why the moon template sensor and high/low forecast temperatures are not rendering?

Thanks for your inspiration and help!

Wow it looks amazing!

Do you use the home-assistant package: esphome-nodes/homeassistant-config/package-display_node.yaml at f7a3a225c417d651b4a3937708ea4d4b2d0827ed · fredrike/esphome-nodes · GitHub

LUNZ · October 23, 2020, 7:46am

Yes I do have the Home Assistant package configured. But it’s probably worth me looking at again

Also, I wanted to ask, how long does it take for your display to refresh? Mine is configured to refresh every minute and takes seven seconds to fully cycle so I’m wondering if I should refresh less often or is there a way to quickly update the clock without a full refresh.
