Hi.

When i read a Profile Generic for the first time through API /api/Task/Add, I do not want to read all the values in the meter.

How can i tell it to get values from date a to date b?

I normally send it like:

{
"Tasks": [
{
"Order": 1,
"Batch": "DC74A838-ADCA-4B6A-B633-AB3E870A2188",
"Object": {
"Id": "E18D57DC-6872-4B69-858C-05848B5585FB"
},
"TaskType": 1
}
]
}

Hi,

All historical (profile generic) values are read from the meter and stored in the database. So after they are read once, the historical values are retrieved from the database and not from the meter.

If you don't want to read all values from the beginning, you can set the buffer read time of the profile generic and the values will be read after that.

Hi again.

How do i set the buffer read time?

Do I just:

Get the attribute value with /api/Attribute?id=*******

and send the starttime in via /api/Attribute/Update?
