If you run the scripts by cron, the most often frequency is once per minute.
PVLng offers a wrapper script PVLng-run.sh to run a script more than once per minute.
# ./PVLng-run.sh -h
Run command each period seconds for 1 minute.
Use in cron with cron period * for each minute.
Usage: PVLng-run.sh [options] -- command parameter1 parameter2 ...
Options:
-p Period in seconds, default: 60 (run once)
-t Test mode
-v Set verbosity level to info level
-h Show this help
I monitor my power consumption and my SMA inverters with the following cron tab entries:
# Fetch plant data each 30s, run mostly during daylight times mostly * 4-22 * * * ~/PVLng-run.sh -p 30 -- ~/SMA/Webbox.sh -s Inverters.conf * 4-22 * * * ~/PVLng-run.sh -p 30 -- ~/SMA/Webbox.sh -s Sensorbox.conf # Fetch consumption data each 15s * * * * * ~/PVLng-run.sh -p 15 -- ~/S0/S0.sh -s Consumption.conf
Don't forget to divide the real script name and its parameters with the "--"
If you run the wrapper script in verbose test mode, it will show you only what will happen:
# ~/PVLng-run.sh -tvp 30 -- ~/SMA/Webbox.sh -s Inverters.conf [19:58:02.550] Period : 30 [19:58:02.554] Command: ~/PVLng-scripts/SMA/Webbox.sh -s Inverters.conf [19:58:02.559] Run, 1 left ... [19:58:02.563] Test mode ... [19:58:32.572] Run, 0 left ... [19:58:32.576] Test mode ...
For more accuracy the wrapper script will spawn the concrete command into background, so it have not to wait for it.
