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.

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

```auto
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

@sebyldino  
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?

v1.2.0 online [here](https://github.com/sebyldino/Homey_e-paper/releases)

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**
