udev rules document for RPI 3

Topics about the Beta trials up to Build 3043, the last build by Cumulus's founder Steve Loft. It was by this time way out of Beta but Steve wanted to keep it that way until he made a decision on his and Cumulus's future.

I made an emty file datatag.txt file and placed it in /home/pi/var/log/ and chmod it 666 (RW-RW-RW-) - then CumulusMX was able to write in it.
and then I checked against this file in stead of the tmp file.
In the file .bashrc in pi's home directory I wrote: sudo su
I hope it is a way to give me root privilliges.

I ran into this a couple of times recently, getting '*** Data input appears to have stopped' in the current MXdiags log, but I like this idea of generating a small file using a tag.

I'm comfortable using cron, but I wondered if one could leverage Settings --> Internet settings --> External programs. Looks like there's the option to run it at each web update interval or realtime interval.

Depending on the timing of the tag-file generation relative to this feature, I suppose this could be behind by one cycle...? I've not tried it yet, but it seems like this might tie the check into CumulusMX pretty directly and potentially synch it to the tag-file generated (more or less).

I've not tried it yet ... mostly because I want to set up a systemd service to handle the restart first... Seem feasible?

Interesting side note: I missed a couple of web updates while I was looking around and I had a short flat line on the temperature graph. After I restarted CumulusMX it appeared to reconnect to my Ambient WS-2080 and update the missing data. It looks like the Weather Underground Catch up feature might have worked, though WU only seems to log every 5 minutes.
