I'm trying to run this on a pi zero w, but it seems to be overtaxing it maybe? (cpu gets warm and locks up).
Second when ever I redeploy any changes to this it breaks the water depth sensor readings, they no longer come in?
flows (2).json (40.7 KB)
It would be better if you could reduce the flow in size so it can be posted directly. Or at least provide a screenshot of the flow to give people an idea of what it does.
What do you see if you run top in a command window?

Are you sure node-red was even running when you ran top? I can't see it there. Certainly the processor was very lightly loaded at that time. What exactly do you mean by 'locks up'?
Run node-red-log and see what that shows when the system locks up.
Also stop and restart node red and post the startup log. Do that by running
node-red-stop
node-red-start
Copy/paste the log and post it the same way as flows are posted.
I would also suggest node-red-status
That may help.
I have never heard of that, and is not present on my system.
isn't that a command that shows the status of node-red?
Oh, interesting.
Did a quick check.
Maybe this one then:
sudo systemctl status nodered
Maybe I did an alias for it and forgot I did.
(Sorry)
Actually I was kind of wrong in another way.
The command was/is:
node-red status.
That will start node red with a flow file called status
Ok. Wow. Seems I am really having a bad time with commands just now.
Sorry to all for any confusion.
It either completely stops responding to anything, or gets stuck in a boot error (it resets itself and gets stuck)
Then what happens if you start node-red in safe mode?
Is it node-red --safe?
See if things load ok then see what happens if you deploy it.
What stops responding? The browser? The pi in a command/ssh window?
Again, it is not clear what you mean by that. Do you mean that the pi reboots without warning? If so how do you know it is rebooting? Then again what do you mean by gets stuck?
If you do mean that the pi is randomly rebooting then this is most likely a power supply issue. If not the psu then probably another hardware problem.
The pi will not respond to a ssh, or browser, just a solid led and nothing will open/load. I know it will restart because it will sometimes show a boot error (led flashing nonstop at regular rate), or it will load and the history has disappeared and the outputs have been reintialized.
It's a hardware problem. Disconnect any external devices, usb for example, and see if that makes a difference (a faulty device can pull down the power supply). If that doesn't help then try a different power supply.
Or it could be the SD card of course.
That might suggest a problem with the SD card
