FileNotFoundError - model.json

[bramstroker]

I have released 1.12.2 btw which includes some improvements to prevent the error reported in this issue.
Hope this solves all your issues.

That's strange. Was there any error before this? I guess there was a problem downloading the profile, there should be an error in the logs in this case. But you say you were running 1.12 already without issues, so the profile should already be there.
Could you double check mentioned directory if there is really no file there?

Also try rebooting one time.

Still doesn't download all profiles. One was missing which I can find in the GitHub repository (Sonoff ZBMINI)

Doenloaded it by hand and rebooted and got this:

@lancer73 JSON is invalid so you probably made a mistake trying to fix manually.

Which error did you got regarding the ZBMini? Same as @GH2user or another error message?
Did problems start occuring for you since v1.12.1 or also with v1.12.0

Yes, you are correct. The wget did not get the intended result. Before was the same as @GH2user. I have a lot of different equipment monitored. Those model files were present.

Retried the download manually and now it is working.

[GH2user]

I have checked the folder and there was no json file in there. The folder structure was in place.

In that case Powercalc thinks the profile was already downloaded and does not try again.
I will see if I can make that more robust and put in some validation.
To force powercalc to redownload the profile you can remove the model folder manually.

Powercalc optimistically create the model folder and after that downloads file from github to it.
Whenever this fails the model folder will not be removed, and this causes the download mechanism to never retry again.

Actually only two brand-folders where there out of the seven showing now after a good reboot. Seems they all got deleted when upgrading.

I see there was an issues with library generation code, where each profile was indicated it updated yesterday.
Also see https://powercalc.lauwbier.nl. Every profile had updated at to: 2024-05-03T09:11:32+02:00
Because of this Powercalc would redownload all profiles which you already had locally.
It shouldn't remove any folders, so I'm not sure why you previously had seven, and now only 2.

I'm working on better error handling, validation and also a retry mechanism to make it more robust and prevent any issues in the future.

Oops I see I did edited your comment with my remarks @GH2user.
Meant to quote reply, no idea what I have been sniffing this morning ;-)

Anyway, I have worked on some improvements for the download mechanism. See #2234
Will release this soon.

• Retry 3 times if Github download fails, with 3 seconds intervals
• Check if model.json is present, when it is not always do a download
• Better errors in the logs.

No worries Bram, happy you created Powercalc and are improving it. Thanks a lot.

I had two folders when the fail happened, so 1.12.1 deleted the folders from 1.12.0. After a fail-free run I had seven of them again.

I'm facing the same issues with the Google Nest mini profile from version 12. 0 and higher. I stay at this moment at version 11.8. This one is working without issues.

Thx, the error with the Google Nest mini profile is gone.
