Gurux.DLMS.Python - Reading "1.0.99.1.0.255 Load profile with period 1, i.e. General load profile" history values

Hi,

I am trying to read history values in Gurux.DLMS.Python (Gurux.DLMS.Client.Example.python folder - GXDLMSReader.py).

When I run the GXDLMSReader.py code - everythink is as it should be (connection is successful, also reading all values, and printing them (in HEX trace) to CMD).

Now I am trying to get "1.0.99.1.0.255 Load profile with period 1, i.e. General load profile" history values. Before that, I have specified which OBIS code to capture in load profile

I have added 4 items via MC software:
- 0.0.1.0.0.255 Clock
- 1.0.32.7.0.255 Inst. voltage L1
- 1.0.52.7.0.255 Inst. voltage L2
- 1.0.72.7.0.255 Inst. voltage L3

I tried to read "1.0.99.1.0.255 Load profile with period 1, i.e. General load profile" with Gurux GXDLMSDirector - successful (picture in attachment).

Which function (in Python) should I use? When I specify OBIS code for Load profile, do I have to specify also the items "inside" Load profile (0.0.1.0.0.255 Clock, 1.0.32.7.0.255 Inst. voltage L1, 1.0.52.7.0.255 Inst. voltage L2, 1.0.72.7.0.255 Inst. voltage L3)? What do you suggest?

Thank you for your answer,

Best regards,
David

Hi David, You can define…

Hi David,

You can define capture objects or you can read them from the meter.

You can do it like this:

pg = GXDLMSProfileGeneric("1.0.99.1.0.255")

#Read capture objects:
self.read(pg, 3);
#Read buffer by start and end time.
self.readRowsByRange(it, start, end)

with:

this python part:

pg = GXDLMSProfileGeneric("1.0.99.1.0.255")
self.read(pg, 3)
start_time = datetime.datetime(2023, 9, 1, 0, 0, 0)
end_time = datetime.datetime(2023, 9, 6, 0, 0, 0)
Data = self.readRowsByRange(pg, start_time, end_time)

for item in Data:
timestamp = item[0]
UL1 = item[1]
UL2 = item[2]
UL3 = item[3]

print(f"Timestamp: {timestamp} | UL1: {UL1/1000} V | UL2: {UL2/1000} V | UL3: {UL3/1000} V\n")

The only thing interesting here is the timestamp - somehow the timestamp values are not correct (while in GXDLMSDirector are correct).

Hi, To provide you with more…

Hi,
To provide you with more info...
I also tried with getYear(), getMonth()....:

for item in Data_ECO:
ti = item[0]
UL1 = item[1]
UL2 = item[2]
UL3 = item[3]

year = ti.getYear()
month = ti.getMonth()
day = ti.getDay()
hour = ti.getHour()
minute = ti.getMinute()
second = ti.getSecond()
timestamp = f"{month:02d}/{day:02d}/{year % 100:02d} {hour:02d}:{minute:02d}:{second:02d}"

print(f"Timestamp: {timestamp} | UL1: {UL1/1000} V | UL2: {UL2/1000} V | UL3: {UL3/1000} V\n")

I always get the following error:

year = item[0].getYear()
^^^^^^^^^^^^^^^
AttributeError: 'GXDateTime' object has no attribute 'getYear'
Ended. Press any key to continue.

Hi David, You can loop rows…

Hi David,

You can loop rows like in the Python example.

https://github.com/Gurux/Gurux.DLMS.Python/blob/430bf80789e45f8a61ce688…

You can get the year from the Python date time object like this:

year = ti.value.year

Hi, Thank you for your…

Hi,

Thank you for your answer and your help. I really appreciate it.
I have just one more question. When I look at the timestamp, I notice that the timestamp value equals the date, when the power meter started capturing measurements (for ex. if I turned ON the power meter, and the first capture was made at "2023-09-07 11:40:00", then this date is present at all measurements, until:

- new day, then it is the first capture date of the new day,
- powering the power meter ON (after being turned OFF for ex. some days) and then the first capturing date is stored.

I noticed that also in MC software (reading with buffer) when I right-click on the data in Clock row in "Load profile with period 1, i.e. General load profile Logical name: 1-0:99.1.0*255", and change the "time" from "Computer time" to "Device time" (pic in attachment) - the first capture was made at "2023-09-07 11:40:00" and only this date is visible, others are "not available". When I change time back to "Computer time", dates come back correctly (if capturing period is set to 300, then times have 5 min differences).

My CMD output also have "first capturing date":
------
item:
[<gurux_dlms.GXDateTime.GXDateTime object at 0x0000011BBBB2DC40>, 232169, 232246, 232286]

Timestamp: 2023-09-07 11:40:00 | UL1: 232.802 V | UL2: 232.883 V | UL3: 232.923 V

item:
[<gurux_dlms.GXDateTime.GXDateTime object at 0x0000011BBBB2DD00>, 232953, 233029, 233077]

Timestamp: 2023-09-07 11:40:00 | UL1: 232.953 V | UL2: 233.029 V | UL3: 233.077 V
------

My question is - do I have to "manually" calculate tha DateTime (if capturing period is set to 300 sec for example, adding 5 min to the datetime until it is not equal to the previous datetime)? Or did I go wrong somewhere?

Thank you for your answer and best regards,
David

Hi, You can use…

Hi,

You can use readRowsByRange method. You can give start and end time and the meter returns values between the dates.
