I have just implemented a couple of scripts to use `uhubctrl` (which does
control the RPi's USB port):
#!/bin/bash
# monitorlockup
# watch the weewx log file for lockup condition and use USB power
recycling to clear the lockup
# 20190622
LOGfile="<path-to>/weewx.log"
tail -Fn0 $LOGfile |
while read line ; do
echo "$line" | grep -q "Errno 110"
if [ $? = 0 ]
then
/home/weewx/powercycleusb
fi
done
And
#!/bin/bash
# powercycleusb
<path-to>/uhubctl -a off -p2
sleep 45
<path-to>/uhubctl -a on -p2
Both scripts are executable, owned by root and also setuid root.
`monitorlockup` will run from /etc/rc.local on boot (I trust).
Note: The -F (CAPS) in `tail` should track the logfile despite any log
rotation.
It is possible that the 45 second `sleep` could be reduced.
My logs show approx 2 minutes between the first (of 4) prints of [`Errno
110]`
so I hope to have the console restarted and stable before `weewx` resets
itself.
Does it work? Time will tell...
