NSPanel, esphome and can't download TFT display

[DomBog]

Hi,

I was fascinated by NSPanel from Sonoff and the idea to have 2 buttons and a mini display to show some information. Lighter than a tablet (with update/maintenance). The idea was perfect.

At the end, each update is a total nightmare. between 3 to 7 days, my 3 panels doesn’t work and show what any IT people is afraid : the bluescreen and the nspanel who loop busy to reboot …

I follow Blackymas blueprint setup and I try all options that it seems correct.
Btw, it can work easily (4.3.39 to 4.3.42) but after don’t (4.3.42 to 202510.0)

I have no logical explanation

I proceed to

• reimport blueprint
• copy nspanel_us.tft and nspanel_blank.tft in home assistant.
• I update the module
• clean all
• install one by one

and now the nightmare begin because nothing is logical. Some device can work as a charm immediately (let’s say a couple of hours…) and other don’t

the diagnostic card show this

Homeassistant is HAOS debian image virtualized with KVM through OpenMediaVault

I can ping and reach the nspanel, home assistant. I can do name resolution. All seems correct

But

If I choose TFT display “NS Panel US” for me, It wil ltry to download the tft from github

Ok, let’s try locally, I choose “nextion_update_url”. Btw, I can use the URL and download immediately the tft file from my desktop but I remove Firewall/Internet/DNS stuff.

To resume:

• log aren’t very verbose even in debug
• no clue
• update break without reason

Any idea before I smack it with my best hammer?

Thanks in advance if you read and specially if you have an idea

They tend to have a lack of memory issue…
Check in the post for that blueprint to see how they dealt with it.

Otherwise Try this but read the the last post from Edward (the Author) near the bottom of the thread.

Sonoff NSPanel Blueprint - Configure your own custom NSPanel easy via a Blueprint

Hi @ all, [Open your Home Assistant instance and show the blueprint import dialog with a specific blueprint pre-filled.] This is the FIRST and ONLY custom version of the “Sonoff NSPanel” that is easy to configure via Blueprint and does not require much installation or code line changes. You can find the full project on GITHUB [2 Home][3 Buttonpage] (More images see below)   Description This project allows you to configure your complete NSPanel via a Blueprint with UI. That means you…

I am not much of a precise help for a solution, this was 2+ y ago and I did mess a lot with the esp and tft so maybe (hopefully) your case is less complex.

+1 for @Sir_Goodenough

I remember to have had issues with the baud-rate, may want to lower this.

If you modified the tft then start with a smaller one, i.e. return to the one that was working before. With me similar issues after I accidentally added a larger picture as background. At one point I was only able to upload via cabled connection to the screen itself, reloaded a the default TFT and started from scratch…

Hi,

thanks for your information. I tried several baudrate through the web interface but it changes nothing. the logfile indicate anytime I want to download the tft “change baudrate to 115200”

After reading this usefull link, I was searching for network issue (I read a bunch of thread everywhere about this) BUT when he mentions memory issue, it pops in my head.

Whatever I do (install wirelessely or through USB connected), when I start the device, Is see the TFT version. (4.3.34 or whatever), the TFT doesn’t change or was erased. SO, it keeps in memory the old version and maybe the system is unable to download a new version due to lack of space in memory.

I change my local file “nspanel_us.tft” with “nspanel_blank.tft” ( +7M vs 700k).
Success, a black screen comes with a QR code in it.

I revert and …

I crossed my fingers and my toes and it works.

Wipe out and reinstall. Like good old time of DOS/Windows

Thanks for your help.
