Hello to everybody,
first of all MANY THANKS to Bernd! Great project. Sofar I have extended it with weeksday, an alarm clock and a new language "allemanic". Everything is working fine, even the API, which I was able to extend, too.
My problem: I have no idea how to excess the API from an APP (to control the wordclock with a smart phone).
Is the anybody out there (sorry stolen from Pink Floyd), how maybe could show me some lines of code (like the *.html) , e.g. one button sending directly a "POST" or a "GET"?
Thanks a lot in advance and have a nice evening
Best regards
Peter

Well, it already has a build-in "APP": the webinterface.
Just go to the IP address of your clock on your smart phone.
On an iPhone you can even then put it on your Home Screen: then it actually feels like a normal APP.

Hi Frank,
thanks for the feedback. You are right, this part is working fine.
Browser => http://192.168.2.139/api#/API =>
1
2
So e.g. 4. steps are required to change the brigthness.

  1. "POST, 2."Try out", 3. Enter new value, 4. "Execute"

Means, I'm searching for the code, which I can adapt: change brigthness with one buttoen (taking the "Execute" button, move it to another site, change style and so on)

Does this descripton make sense to you, or is my writing still bad, not understandable (don't worry, just let me know :)
Many thanks
Peter

Hi Peter. Just to be clear: you are aware that this APP implementation already exists?
In your case http://192.168.2.139

Frank.

Hi Peter. This is a known issue: #218
Best would be to start using the latest (Python3) branch.
Please let me know if this is possible for you.

Hi Frank,
I updated python to 3.11, but still having the same problem.
I tryed your "new" webinterface (FrankX0@0edce92)?
Ending up with the error "module web could not be imported" and installing endet up with some more errors...
I'm so sorry...
Best regards
Peter

Did you update Python or did you install the latest wordclock branch?
If not done so, you should follow the Software setup.

I think I give up.
after "sudo pip3 install -r requirements.txt", I'll get
Could not find a version that satisfies the requirement astral==2.2 (from -r requirements.txt (line 2)) (from versions: 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.6.1, 0.6.2, 0.7, 0.7.1, 0.7.2, 0.7.3, 0.7.4, 0.7.5, 0.8, 0.8.1, 0.8.2, 0.9, 1.0, 1.1, 1.2, 1.3, 1.3.1, 1.3.2, 1.3.3, 1.3.4, 1.4, 1.5, 1.6, 1.6.1, 1.7, 1.7.1, 1.8, 1.9, 1.9.1, 1.9.2, 1.10, 1.10.1)

Hi Peter. Don't give up. We'll get this sorted out.
From the reports I conclude you are running an outdated Python3 installation.
Can you execute python3 --version?
Are you running the latest Pi OS version (bullseye)?

I agree this is probably the right time to start fresh and moving to bullseye.
I have my clock running on bullseye, so I expect you will encounter less problems (fingers crossed).

Good luck,
Frank.

Yes you have to use bullseye (or Buster as a minimum).
It is not working on stretch.
Maybe we should mention this in the docs @bk1285

And it is not a long way ;). It is much easier as you might think.

@PeterBrenden

Sorry, It's me again, but I think with fairly good news
So far bullseye is done. ssh is working, everything according to https://rpi-wordclock.readthedocs.io/en/main/doc_software_setup.html

Is this right source ? git clone https://github.com/bk1285/rpi_wordclock.git
Because running the wordclock gives an import error:
ImportError: cannot import name 'parse_rule' from 'werkzeug.routing' (/usr/local/lib/python3.9/dist-packages/werkzeug/routing/init.py)
I tryed both installing werkzeug 2.1.2 and the betterone werkzeug 2.2.2

Hi Peter,
That is good to hear!
I guess the APP now also works as intended.
If you are extending the functionality you might want to share through a pull request, if you think it could be useful to others.
Kind regards,
Frank.

Hi Frank,
yes the APP is running fine!
For now I'm still struggeling with some little challenges, getting my version running on the new plattform (e.g. python2=>3, changes and improvement within your latest wordclock-version).
I'm sure whether my code is that good, some one else would enjoy :) We will see later.
Again many thanks
Peter

Hi Frank,
sorry, it's me again. I implented my function, one by one. With last one (sound) the APP worked "for a while", but the browes can't reach it anymore (ssh is still working). Does this error message makes sence to you?

Just in addintion, in case it helps: I did
sudo apt-get install sox
sudo apt-get install libsox-fmt-mp3

I think I can stop for now and we could close this issue. I think I have to search for another soundplayer. I'll let you know, when it is hepofully done.

(reasons: with bullsey sox +APP does not work; sox+soundplayer works "sometimes".)

First think for me to do is to learn threading, since I have never done this.

Again many thanks and enjoy programming
Peter
