Smart meter in logfile

[Franzie]

I just installed a smart meter cable. Now, when I look into my logfile I see every second a notification from this meter. Is this normal? That often?

Yes, every 10 seconds there is an update

Hi Franzie,

That may be correct. It depends on the protocol of the smart meter. Older Smart Meters, with protocol DSMR 4.2 or earlier, emit a telegram every 10 seconds. The newer smart meters, with protocol DSMR 5.0 or newer, emit a telegram every second.
That fills the log file quite fast. However you can limit the number of updates by setting the "Rate Limit" in the hardware for the smart meter to the number of desired seconds.

What can be a reasonable amount of updates?

1 update per 10 seconds.

Personally I use 1 update per 10 seconds as well. That is fine for me.

Thanks!
More than enough

Same 'problem'... instead of increasing the rate limit can't we configure the amount of logging (e.g. turn it off) it does somewhere?
When it is working It is just generating too much log information if you ask me.
Every second (or even 10 seconds) I get this which is not really meaningful:

I am curious about this too!

A fresh smart meter was installed here friday, and last night I saw that my used hdd space went from 17% to 48% within a week! On a 32gb card...

I have set the interval to 30 seconds now, also because my Raspberry was quite Hot because of all the updates..

But if someone knows a way how to free some hdd space, it is more than welcome!

Hi does anybody have an update on this ? Is it possible to disable this meaningless logging ?

'Meaningless" is kind of a subjective remark here but yes it is possible to disable the logging for this and all other logging in this class.

edit the file /etc/init.d/domoticz.sh and change the line with

Code: Select all

DAEMON_ARGS="$DAEMON_ARGS -loglevel  normal,status,error"

to

Code: Select all

DAEMON_ARGS="$DAEMON_ARGS -loglevel  error"

save the changed file and exit the editor
then

Code: Select all

sudo systemctl daemon-reload
sudo service domoticz stop
sudo service domoticz start

and you won't get these loglines in the GUI and / or in the OS logfile
