Hello, I m on a new project and like usual I m asking if someone can be interested by the code to see if I m make it public or not.

This time it's a dashboard made with e-paper display.

It's 100% powered by battery, the first part is just meteo, the bottom part with graph and the "to remember list" part is managed by domoticz widget.
For information, for my use it will be updated only every 24h, but if you want to use sensors return can make a 1h update for exemple.

The base is from this project https://github.com/lmarzen/esp32-weather-epd with
- Use another API for meteo, free and without registration
- Remove useless stuff for me
- Add the domotics API connexion
- Install the device in an IKEA frame
- Rewrite the display, orientation, data, size (to fit the ikea device).
- Remove the hardware/software part for integred sensor.


The code is not friendly at all, for exemple the graph display my consumption on last days, with the one year later values to compare, if you want to display others stats, you will need to recode all this part.


Here the ikea frame used https://www.ikea.com/fr/fr/p/roedalm-ca ... -00548863/

Nice project. In september 24 i bought a small 2,9 inch e paper module to build a display of energy usage/flows for my energy closet door. I did not find the time to get this running Domoticz, so a starting point would be very nice. In time i will pick it up and see if i can fit the energy flows etc on it. But 1st project will be to get actual data from my solarpanels.
Thank you.

I will put files on a github page this week.
But for information, this kind of device is not good for "real time" display, because of the flickering when updating.
But they are perfect for low powering device that display daily information, plant irrgation, cat food, calendar, ect ....

The library used have fonction to draw on screen, circle, box, line, so you can reproduce the "domoticz energy dashboard", I have found one (with the home assistant one, but it's the same) but I don't found it again.

There is so much dashboard on e-paper on google.

Oke, thank you.

My original idea was to simply show what is going on behind the door of the electricity closet, so electricity in / out etc. Just simple text that fits on a 2,9 inch.

The e-paper is new to me so i have to see what happens.

But ideed flickering could be an isue.
