EASTRON SDM120C - RS485 Modbus meter

[Pongo]

Hello,
I added a control: checks if all requested values are returned.
Returning OK or NOK.

Can you please try it?

Hello,
Thanks, i am testing that and i let you know

Hello Pongo,
So far it is really stable.
Thanks for your job

[Pongo]

I'm happy to help you.

I have 2 questions:

1. getting http://localhost/metern/programs/programtotal.php I can read "Totalcounter" and "Dailycounter", but at midnight I have 0 for both values. Why? It's a bug?
2. I exchanged my pulse meter with sdm120c, leaving old values. Now I created a simple scritp that echoes a fixed value (last meter kWh value), testing it on admin page is ok, but metern doesn't write it on .csv file

Code: Select all

pi@pi-alarm ~ $ old_pdc.sh
3(480254.39*Wh)

I inserted manually value 0 for new meter on ID 1 column and moved ID 1 values to ID 3.
I thought last meter vale would have been repeated every row, but I have this

Code: Select all

17:30,0,32641184,480254.39
17:35,0,32641184,480254.39

Can you help me, please?

EDIT: for question number 2... I solved. I stopped metern, webserver, updated csv file, restarted webserver and metern, and now it's ok... column for ID 3 is filled for every row.

Hello Pongo,
For the 1) I will look at what happen at midnight. Obviously the Dailycounter should be equal to 0 but not the Totalcounter.
For the 2), i don't understand it all but as the FAQ say: be careful when decommissioning a meter. That's the ugly part when working without db.
Have a nice day

Hello Pongo,

For the "Totalcounter at midnight", it may happen that the values aren't returned during few seconds because only the header is created in the daily csv.
Is it a real problem for you ?

[Pongo]

Hello,
I was using programtotal.php to read total energy without phisically reading csv files.
It would be good if totalcount was on shmop.
But I can read them.
No problem

Thank you

[jeanmarc]

Ok i'll put total counters back in shmop too

[Pongo]

Thank you... if possible also Daily count.

Thanks

[jeanmarc]

Hello,
To keep the code clean, i will put the value at midnight as well as the total value in shmop. (The day are simply the difference)
But, if you reboot your logger the midnight value will obviously being lost 'till next day..
