Getting Active power in kW

Forums
General discussion

Hi Mikko,

My custom meter is calculating the active power in kW but in the DLMS Blue book only W (enum 27) is defined. The requirement for us is to send the active power in kW only. How do I do that and make the units as kW?

Regards
Sidharth

OBIS codes for use case

Forums
General discussion

Hi Mikko,

I am adding DLMS compatibility over serial port to my custom single phase electricity meter and I needed some help in figuring out which OBIS codes would be appropriate for my use case. Here is my use case.

I measure the following meter parameters from the metering chip every 15 seconds and put them in an array:
1. Current RMS
2. Voltage RMS
3. Frequency
4. Wide band power
5. Fundamental power
6. Reactive power
7. Wide band energy
8. Fundamental energy
9. Reactive energy
10. Phase angle

I'm investigating your solution for reading data from the meters in Portugal. The software we will use to read data from the meters only support javascript library. Do you have any libraries that we can use in our software ?

Thanks in advance,

Push Load Test

Forums
General discussion

Hi Mikko,

We have created one Push Listener service. In that, we are receiving push notifications from meters and do the parsing.

Now we want to do a load test for 1 Lakhs of the meter. Is it possible to send 1Lakhs of push data concurrently to service?

Can you please provide any suggestions on this?
