@sebyldino my e-paper keeps rebooting, serial monitor shows “E (4027) rmt: rmt_driver_install(1023): RMT driver already installed for channel” do you have an idea what can be the cause / solution? Thx.

ps. lovely project!

Have the same problem here, no idea where that comes from, probably something stupid I did?
Hope that @sebyldino can tell us what to do.

Looks very interesting share some photo’s guys!!
My question: i have no 3d printer. What are the possibilities to print. I googled, but everywhere it’s the same; only for companies or no way to figure out what the costs will be. Tips are welcome.

JCLPCB does a wonderfull 3D printing job for a good price. I used their resin (sla) printing service already several times.

Hello,
I will try new install with erasing all flash content to check if i get the same error and i will let you know if i found what happen.

You can try to upload code another time with parameter “Erase All Flash Before Sketch Upload” to “Enable” to clear all contents in ESP.

Did another upload with 'Erase all flash", unfortunately same result, a part of the monitor:

10:01:45.050 → entry 0x400805f0
10:01:46.876 → .IP address: 192.168.2.69
10:01:49.602 → E (3805) rmt: rmt_driver_install(1023): RMT driver already installed for channel
10:01:51.787 → ====== ERROR MESSAGE ======
10:01:51.787 →

No compiler errors, just one warning: “null” characters ignored ( I did remove them ).
main\imagesAndFonts.h:140:1: warning: null character(s) ignored

Other demo sketches do run without problems.

Nooohhh, great stuf. Do u have a link to the 3d file?

Look at the Github page, STL files

Added 2 lines to firstStart() :slight_smile: now it’s starting up:

void firstStart() {
  if (firstStartTime) {
    zonesSettings();
    epd_init();
    epd_poweron();
    epd_clear();
    epd_draw_image(backgroundArea, (uint8_t *)firstStart_data, BLACK_ON_WHITE);
    epd_poweroff();
     firstStartTime = false;
     error = false;
  }
}

There is still the error msg:
18:04:29.466 → E (5880) rmt: rmt_driver_install(1023): RMT driver already installed for channel

I haven’t had time to try it yet! Great if you found it, I must have made a mistake during the last modification. thank you for sharing, I try on my side and update the Github. This message doesn’t tell me anything. :thinking:

Great work. Thinking I might try this. Just to clarify. There seems to be some optional backsides to your stl case files. Which of the files are required? The case and one of the others?

Found and fixed the error.

v.1.1.3

@JPe4619 thank you! It was almost what you found! It helped me a lot. :wink:

Fixed it for me, thx.

v1.2.0 online here

Added: battery capability to Homey

Now you can see the battery of your Homey e-paper on Homey, and use it in flow!

If you have already added your Homey e-paper to Homey, you have to remove it and add it another time.

WARNING: it will make your flows KO
