Works with ESPHome in Home Assistant | Seeed Studio Wiki

The XIAO ESP32C3-powered 7.5-inch E Ink® Display is a compact, energy-efficient solution for showcasing Home Assistant data.

Regarding the point 4. Image example with Home Assistant Puppet, my advice would be to use BMP instead of PNG, as this will almost certain give memory errors.

For example:
online_image:

• id: dashboard_image
  format: BMP
  type: BINARY
  buffer_size: 16000
  url: http://192.168.1.15:10000/lovelace/simple-dashboard?viewport=800x480&format=bmp&eink=2

Having an issue where ~80% of the display fades (All but lower right corner when facing display.) Performing a hard reset (Power Cycle) temporarily corrects the problem, but it starts to fade within minutes. Is this a HW issue or do I need to add a code block to "bounce" the device.

Thanks.

Hi,

The issue you're experiencing may be related to the driver board. I recommend contacting our technical support team at [email protected] for after-sales support.

Is it possible to show more events frome one calendar?
The calendar.list_events is not working anymore with the latest versions of HA and the entity_id: calendar.xxx show only one event of the calendar.

[nfs0619]

Thank you for your feedback. Unfortunately, this is a limitation of Home Assistant. It can only read one event from a calendar entity.

Having a huge issue where the display constantly keeps reconnecting. Tried holding boot while plugging in, holding boot, pressing reset, keep holding boot, then connecting. Nothing works. My panel seems to be BRICKED into a constant disconnect loop, which prevents it from having any other firmware installed. Please helo!

[Allen-Kuang]

Please Try this way. If it doesn't work, take the MCU out from the driver board and try the above way again.

[hazetom]

Thanks for getting back to me swiftly. Doing this (and only this) gets it out of the disconnection loop, and showing up as a COM4 usb device. However, through all the methods (via ESPhome on HA, via https://web.esphome.io/, via OTA, it fails to actually connect with the device (keeps being stuck on 'connecting') and installing anything. Unplugging and reconnecting the panel results in the reconnecting loop returning, unless I do the trick you described. Hope you can help a little more :) Kind regards, Tom Op wo 30 jul 2025 om 04:35 schreef Allen-Kuang ***@***.***>:

Is it ok when you run the demo in our wiki?

If those demos in our wiki don't get your device stuck, but you program get it stuck. In this case you should check your program to find out which line of code make the device stuck~

[hazetom]

Unfortunately, also the demo in the wiki doesn't work. My device stays on the "Begin your smart home Journey", even though I followed all the steps, also troubleshooted with ChatGPT to see if I did anything wrong, but no succes. Op wo 30 jul 2025 om 09:24 schreef Allen-Kuang ***@***.***>:

I'll look it up and will get back to you.

[hazetom]

Thanks! To add more information. I did manage to be able to actually install firmware on it, flash .bin files to it, but the screen is hardstuck on the demoscreen displaying "Begin your smart home journey'. It doesn't cycle through the different demo screens anymore, it did when the unit first arrived here. The device refuses to refresh or do anything with the information I flash on it. I don't know if this is a driver issue or something, but right now it's hardstuck on one screen. Tried installing the .bin with CMD, with web ESPhome, with EPS home in HA, but no success. I recently bought it (2 weeks ago) via Aliexpress via the official seeed store. Op wo 30 jul 2025 om 12:03 schreef Allen-Kuang ***@***.***>:

Do you have Arduino IDE? You can use it to run this demo to check if the device is ok.
display_test.zip

When you compile and upload the program to you device in ESPHome, is there any error reports?
If yes, please take a screenshot and send it to me.
If not, please wait the screen to display. It's a little bit slow and will take a few minutes sometimes.

[petr-nov]

Hi Allen-Kuang. I have a similar problem. When trying to upload the firmware, the "connection" light stays on and nothing happens.
I'm also trying to compile and upload the display_test.zip project via Arduino IDe. The program compiles successfully, but when trying to upload it gives an error:
Serial port COM4:
Connecting....
A serial exception error occurred: Write timeout
I don't know how to insert a screenshot here.
How can I proceed further? What exactly do you mean by "take the MCU out from the driver board and try the above way again". Should I open the display?
Thanks

[nfs0619]

@petr-nov Here “take the MCU out from the driver board” means: please open the display module and remove the XIAO ESP32C3 board inside. Then try to upload the firmware again with the method shown in the picture below.

If the issue still persists after trying this way, we recommend that you contact our technical support team at [email protected] — they can provide you with faster and more detailed guidance.

[hazetom]

To add some more information. I've been able to connect it OTA with wifi - I can install whatever I want on it ....but the screen just won't refresh. Even if I add some lines to force a refresh (or force refresh from HA), the device is just frozen on that one demo screen. Hope this helps! Op wo 30 jul 2025 om 12:18 schreef Tom Haze ***@***.***>:

Hi Allen-Kuang, We're one step closer to the solution :) I have successfully installed the Arduino Display test on my device. I have a demo screen of a ticking clock now. Finally, I can see the device is actually working. I bought the device to work with Home Assistant though, so how do you recommend I proceed from here? ESPHome just like before again (the way it froze my device) or via another route? Kind regards, Tom Haze Op do 31 jul 2025 om 04:05 schreef Allen-Kuang ***@***.***>:

Could you connect your divice to your HA host and upload the program like the following way? I mainly want to see what happy to you divice. So Could you take some screenshorts of the logs or download it and send them to me?

Finally, please make sure your GPIO is right. If anything right but display nothing, it must be your GPIO is wrong.

Hi,

Excellent work! I was able to reproduce demos, but I am currently looking for a way to display the remaining battery level. A quick google search showed that I need to define adc sensor, but I am not sure about the pins since they were all used up before. Any responses are welcome.

[Allen-Kuang]

I'm sorry to tell you that all ADC pins in this device have been used for SPI pins(D0-D3).
