Get Wh for shorter period about voltcraft-sem-6000 HOT 3 CLOSED

The sem-6000 records data by itself without connection to your PC with three different scopes

1. aggregated per hour (call --data day)
2. aggregated per day (call --data month)
3. aggregated per month (call --data year)

There is no more detailled measurement implemented in SEM 6000.

You can continously take measurements by using the --measure command. By doing it this way the device is connected to your PC the whole time

The Volcraft SEM 3600 is able to record data by itself without permanent connection on minute-level.

from voltcraft-sem-6000.

from voltcraft-sem-6000.

The smart meter returns also interim results, e.g. a value of the current running hour.
You could query this interim result by this command

sem-6000 Lamp --data day --print | tail -n1 | cut -f2

If you do this every 10-15 minutes you could calculate the Wh by youself. However, i know that this is not very precise. It is just a workaround since the SEM6000 is not able to raise data in shorter periods.

For more detailled measurements I recommend to look for a SEM3600BT.
