Bug: Can’t update a new device using 3.2.2

[T3mplate-wow]

Hey there,
yesterday a completely new device arrived. So there was sonoff preinstalled on it.
I was using 3.2.2 to flash the device and this worked for the device itself. I saw the entity in HA and was able to switch the relays and see the temperature, state of the buttons ect.
But the screen shows the sonoff page. As I tried to upgrade the screen nothing happens on the screen. The device lost the connection to HA shortly but there was no refreshing/installing on the tft.
As I switched to 3.0 (this one I used for initial installing before, so I knew this version was working) I was able to upgrade the screen.

On my existing devices using 3.1 I was able to upgrade to 3.2.2. So I beliefe it is a problem just happening on a newly purchased device.

Im having the same issue. Newly purchased device. Followed the instructions carefully. Flash was sucessfull and integration was successful. Entities are there but can not upgrade the screen. ESPhome log for the nspanel shows

[02:44:27][E][uart:015]: Reading from UART timed out at byte 0!
[02:44:27][W][nextion:072]: Nextion is not connected!

Would really appreciate the help

Hello friends,

I have the same problem. My display is relatively new.
I have bought it 2 weeks ago.
I have already tried to flash the blank.tft and then go to 3.2.2. All unfortunately without success.

What if you try copying the URL for the TFT file and past into your browser, can you successfully download the TFT file to your computer? And could you please double check the file size after the download with your browser?

[T3mplate-wow]

I am not able to reproduce this anymore, because I installed 3.0 and this one was working.
I am extremely sure that I did everything right. The tft was downloadable/reachable even through the browser.
Update from 3.0 to 3.2.2 or from 3.1 to 3.2.2 works fine. It is just happening when the display is clean with Sonoff from factory

I just bought a new NSPanel and have the same issue. How do you deploy version 3.0?

[T3mplate-wow]

I believe 3.1 will also work. Here you can find 3.0 https://github.com/Blackymas/NSPanel_HA_Blueprint/tree/v.3.0.0
and here 3.1 https://github.com/Blackymas/NSPanel_HA_Blueprint/tree/v.3.1.0

you need to download the nspanel.tft or nspanel_eu.tft. I marked it as nspanel_3_0.tft, so that I can distinguish between.

Then I downloaded the blueprint in this version.

In the ESP Config I used just the first part:

substitutions:

###### CHANGE ME START ######

  device_name: "YOUR NSPANEL_NAME" 
  wifi_ssid: "YOUR WIFI SSID"
  wifi_password: "YOUR WIFI PASSWORD"

  nextion_update_url: "http://HOME-ASSISTANT-IP:8123/local/nspanel_eu.tft" # URL to local tft File
#  nextion_update_url: "https://raw.githubusercontent.com/Blackymas/NSPanel_HA_Blueprint/main/nspanel_eu.tft" # URL to Github

##### CHANGE ME END #####

Don’t forget to insert the right tft file. In my case it was nspanel_3_0.tft.

After this part I added the whole esphome.yaml.
In case of 3.0 this file:
https://github.com/Blackymas/NSPanel_HA_Blueprint/blob/v.3.0.0/nspanel_esphome.yaml
copy the whole text into the esp config under the part mentioned before.

After this you can flash it by wire und update the tft successfully.

Thanks, I tried 3.1 with the US TFT. This got me further, now I have an error that says "Model does not match Device Model: NX4832F035_011C"
I updated via OTA, do you think direct serial is required?

[EvilDemos]

Looks like flashing the 3.0 worked then I updated the tft via link and it works perfect now

From what I saw the Service ESPHome: nspanel2_upload_tft_url does not save the url to update the panel. I have to manually type it in when its time up update the panel

This usually happens, when the upload of the tft is broken and the nextion firmware is defect.
try to upload blank.tft to "repair" the nextion-code, than try again to upload the full-tft.
Also had this case with bad WLAN - uploading blank.tft with another WLAN solved this.

Please take a look at this: #619 (comment)

It looks quite similar and the user solved with another Web server hosting the TFT file temporarily.

So, I believe everyone here got to a solution, right?

@T3mplate-wow, are you ok about closing this thread?

[T3mplate-wow]

In my opinion there is still a bug in 3.2.2 which prevents to install the tft file, when the original sonoff display software is installed. So this is an open bug for all new users of this project.

So if you ask me these all here are just workarounds and the bug is still valid.
If you want to close it I would prefer, if this find a way into the official troubleshooting/known issues page with a clear way to solve the problem. As far as I know the solution is to install 3.0 first and go to 3.2.2 with an OTA Update.

I can try this if you want.
But of course you can also say that this is not an bug and just close this.

[edwardtfn]

You are right, this is still an issue with v3.2.2 and new panels. We have a work around, but not really a fix. For reference, you don't have to install v3.0, you can simply follow those steps from this comment and the result should be the same: #641 (comment)

But of course you can also say that this is not an bug and just close this.

No, I think you are totally right and this should be kept open until it is fixed. 🙂
