Mycodo (web interface) crashing

Just started setting up a hydroponic system on a raspberry pi 4 running mycodo on a freshly installed SD card setup using the official raspberry pi imager.

Im not running the system yet, but if I leave the pi plugged in for some time, im unable to access the webfront. Some times I get a nginx error (I think it was 502), sometimes its just not loading.
I can still access the pi via putty. Next time it crashes, I have to check if the daemon is still running.

There some other curiosities that might be related

  • When creating or deleting a widget in a dashboard, it often times out after I hit create / delete. A reload usually helps, but sometimes I just loose it.
  • Every time I access the webfront for the first time after a reboot I get a warning saying that its unsafe and the certificate is bad

Looking through the log files, the only one that seems to hold some valuable information is the web server error log:

This indicates you are using a camera to stream video to a dashboard.

Do you happen to have a video feed on your dashboard? Video is very prone to issues and I would recommend deleting this widget and if you must have a feed from the camera, use the photo option, not video.

This is expected. Mycodo uses a self-signed SSL certificate. Your browser is warning you that it is self-signed and it is safe if you expect it to be self-signed. If you whitelist the address you don’t have to see this warning.

As a test, can you remove the camera widget or at least change it from video to image, then see if the issue persists?

The issue I believe comes down to the ability of the Pi to keep up with serving images to the browser. The default video stream width and height setting is 1024x768 and if we look in camera_picamera.py that serves the stream using the picamera library, we can see a 0.05 second wait period between frames:

When you start a video stream, you may have noticed that the video begins to lag, progressively getting longer and longer. This is likely due to the Pi acquiring images faster than it can serve them at the set 1 / 0.05 = 20 frames per second. This backup I believe is what’s causing timeouts and other resource issues.

There are a few things that can be done to help this. First, you can reduce the video stream resolution, which sends less data for each frame. However, I just now discovered an even better solution which involves changing the frames per second from 20 down to a smaller value, such as 2. I haven’t experimented enough to know at what point streaming becomes unstable, but it’s likely somewhere between 2 and 20, which can also be affected by the stream resolution.

I’ll go ahead and add a camera option to set the frames per second and set the default somewhat low and the user can decide to increase it and see how their system can handle it.

I went ahead and added a Stream Frames Per Second option for streamable cameras and set the default to 5 fps. This will be available in the next release, but if you want to test before then, you can upgrade to master.

You might be right. I was just playing around and added a cam to the dashboard. Its a pi high res, probably doesnt make it better.

I deleted the dashboard entirely and so far I havent seen any issues. Fingers crossed:)

Good idea with the frame cap. I dont see many systems, where a high framerate is needed.

Just following up after a few days to see if your issue was resolved.

Yup. So I’m sure it was related to the camera as you suggested
