Hello pd1acf

I have this indicator on the dashboard and index.. look the images

That I want to have from metern is I can find it every 2 -3 minutes the current power (Amps)

I'm not a programmer but below I mention a way how could this be done..

1.We will need to script the following variables

#Value for Time interval measurement of Wh .. example for 3mins =0,05 , for 5mins=0,08

# x=3mins/60mins=0,05 or x=5mins/60mins=0,08

interval_time= 0,08

#The number of phases

phases= 3

#power factor

power_factor= 0,9

#path for temp log where keep every (interval_time) the sum of Wh (Perhaps this can be done with an internal counter without having to write a log)

log_interval_Wh= /var/www/metern/int_Wh.log

#Path for log where write the value of current power(Amps)

current_power_log= /var/www/metern/current.log

2.Now if we have the above is possible to know the current value of amps and appears at metern.

Suppose we have the following situation..

Within 3 minutes have accumulated 10 kWh and have 3 phases 230 volts with power factor 0.9

The script now will do the following calculate with the value from int_Wh.log and the result will record in file current.log

10 kWh/0,08 = 125000 Watts / (3*230*0,9) = 201,2 Amps

Now the current log will put on live comand of metern

"more /var/www/metern/current.log"

Perhaps some of the above to be a much better way or metern can already do now but as I said I have no knowledge of programming.

Just give you an idea of how it could be implemented..

Thank you
