Once per day data collection

[TrevorJMarshall]

Hi Douglas-

Thank you for your rtlamr contribution.

I recently purchased a Nooelec NeSDR and have been successfully reading my gas and electric meters using your rtlamr software with the Debian Linux operating system.

For a few days I used the suggested two terminal windows, but have moved to shell scripts run from a single terminal as follows:

(gas meter script gmeter.sh)

rtl_tcp &
sleep 6
go/bin/rtlamr -filterid=xxxxx -single=true -msgtype=scm+ | tee -a gmtr
sleep 6
pkill -2 rtl_tcp
wait
exit

(script for electric meter similar)

With shell scripts the rtl_tcp process needs to be killed with a SIGINT (2) signal (equivalent to ctrt-C in Terminal) otherwise the dongle remains on and becomes quite warm. I only wish to take readings once a day.

My next step is automatic daily logging, so my question is:

Would your rtlamr-collect logging software be adaptable to this once a day dongle power-up scheme or should I develop my own method using cron, shell scripts and so forth?

I imagine other people have similar needs.

Best regards, Trevor Marshall

rtlamr-collect does take input from rtlamr and maintains some state to avoid storing repeated messages, but it is intended to be run all the time, same with rtlamr.

There's not really any reason you couldn't use rtlamr-collect this way, it's just not really designed with this use case in mind, it will happily send any data you provide it to influxdb.

OK, thank you. You answered my question. I will attempt to use rtlamr-collect as an interface between rtlamr and influxdb. Do I need to report back on success, or should I "Close with comment" (Git messaging neophyte here)

You can close it if it resolved the issue. You can always come back later and comment your results on this issue.
