EDIT: ok, so I see where my version issue has come from. Because I kept my original ‘substitutions’ section, I didn’t have version: 4 included in the code. I’ve updated that on panel #2 and all seems good.

Panel #3 still has a white screen. I’ll try updating it’s code to include the version 4 bit and see what happens

EDIT 2: NS Panel #3 has been updated but still has the TFT issue. I hit update TFT again and have the crazy slow update in progress once again…

The upload shouldn’t take more than 15 to 20 minutes. If after half hour it isn’t close to the end, you should stop and try again. Those life long transfers always fails at the end.

491

Why are you using the full code and editing it? Why not using a reference to the file in GitHub so you can get all the updates? We can still handle customizations if that is what you need.

492

From the logs I can see the Nextion display is not connected to ESPHome:

[23:12:24][C][nextion:123]: Nextion:
[23:12:24][C][nextion:124]:   Device Model:     
[23:12:24][C][nextion:125]:   Firmware Version: 
[23:12:24][C][nextion:126]:   Serial Number:    
[23:12:24][C][nextion:127]:   Flash Size:       
[23:12:24][C][nextion:128]:   Wake On Touch:    True
...
[23:12:24][W][nextion:078]: Nextion is not connected!

So the TFT file cannot be transferred.

Power cycling the device will probably help.

493

I had the same problem but It is solvable bij putting the tft file locally (in the www map of HA). Make sure you put the path to the tft in you ESPhome-Yaml fil like below:

nextion_update_url: “http://192.168.X.XX:8123/local/nspanel_eu.tft”

Restart the panel → go to settings → devices → ESP-home–> nspanel → Restart butten → Exit reparse → upload tft.

This method work with me

I have done it numerous times, same result and same problem on both devices I own

495

this is what I do, local update
never tried the online (github) approach

496

Same here. With multiple power cycles i can get the blank tft to install but no luck with the real tft file.

It always fails at 17% with the following lines in the log:

16:59:16][D][nextion_upload:048]: Requesting range: bytes=1327104-1392639
WARNING nspanel1.local: Connection error occurred: [Errno 104] Connection reset by peer
INFO Processing unexpected disconnect from ESPHome API for nspanel1.local
WARNING Disconnected from API```

Edit: The 7th attempt worked!

I was originally using the ‘advanced config’ and have just stuck with it. (mainly because it includes the section for fixed IP address etc.)

498

No matter how many times I try, I keep getting these slow /failing TFT updates with this particular NS Panel…

499

I followed this approach and made some progress
https://github.com/Blackymas/NSPanel_HA_Blueprint/issues/443
but got stuck on this

I’ve tried numerous reboots and reflashing esphome but no luck

So you installed Tasmota on it? (as per this post)

501

correct, I followed this procedure
https://docs.nspanel.pky.eu/prepare_nspanel/#configure-tasmota-template-for-nspanel

and then flashed nspanel_eu.tft and esphome

502

I’m guessing this can’t be done OTA then?

503

yes, flashed tasmota with serial and then TFT and ESPhome OTA

504

Thanks, I’ll give it a try when I get time.

505

use this instead
https://tasmota.github.io/install/

and select nspanel from the dropdown menu

I had the same problem and I solved it by deleting and reinstalling both the esphome sketch (deleted completely and recreated) and the blueprint (deleted and recreated from scratch). The error was caused by the fact that the Blueprint did not correctly find the name of the esphome sketch!

Those things are easier now with v4.0.
