How to get data from smart meter using Push mode in .net

Hi,Our requirement is,need to receive data from the meter and saved to our database.

so we can configure Push.Listener and host to the server is enough right??

Hi,

Thanks for the confirmation.

Now,meter is sending data to .net Push Listener in the form of bytes and I converted bytes to Hex string

How i can decode this hexa string?

Thank you

Hi,

Thanks for your response,as you suggested created parser now i can able to get the data.

But we have two meter manufacturer,one manufacturer sending data with DLMS only

00 01 00 01 00 40 00 78 DB 08 44 45 49 FF FF FF FF FF 6D 20 00 00 00 06 19 BB 60 D0 86 AF 25 5C FE BB 5B C7 FD 6E AC A1 7E 0E 06 B2 58 BD EE 30 DF 4D DE 85 6C 60 0B 9F 3D B3 15 DB DA 34 E9 13 E8 4C 49 A6 22 DB 93 2F CC 67 5D 98 A0 BB C8 6A 7C 03 72 78 EF 52 DE EE 64 D7 F5 E1 89 ED CC 42 94 4D B1 8B 53 45 16 1F 1C 9B 40 0C 37 AB 6B 35 04 0E 71 E4 D1 56 B9 79 FA 74 54 68 33 4D C0 91

So how i can decode this data

Hi,

I am using following method to convert dlms data bytes to readable format

async void OnReceived(object sender, Gurux.Common.ReceiveEventArgs e)
{
Console.WriteLine(DateTime.Now + " Data received-" + e.SenderInfo);

try
{

lock (this)
{
if (trace)
{
Console.WriteLine("<- " + Gurux.Common.GXCommon.ToHex((byte[])e.Data, true));
}
reply.Set((byte[])e.Data);
//Example handles only notify messages.
GXReplyData data = new GXReplyData();
client.GetData(reply, data, notify);
// If all data is received.
if (notify.IsComplete)
{
reply.Clear();
if (!notify.IsMoreData)
{
try
{
// Make clone so we don't replace current values.
GXDLMSPushSetup clone = (GXDLMSPushSetup)push.Clone();
clone.GetPushValues(client, (List<object>)notify.Value);
//Comment this if the meter describes the content of the push message for the client in the received data.
foreach (var it in clone.PushObjectList)
{
int index = it.Value.AttributeIndex - 1;
Console.WriteLine(((IGXDLMSBase)it.Key).GetNames()[index] + ": " + it.Key.GetValues()[index]);
}
}
catch (Exception ex)
{
Console.WriteLine(ex.Message);
}
try
{
//Show data as XML.
string xml;
GXDLMSTranslator t = new GXDLMSTranslator(TranslatorOutputType.SimpleXml);
t.DataToXml(notify.Data, out xml);
Console.WriteLine(xml);

// Print received data.
PrintData(notify.Value, 0);

//Un-comment this if the meter describes the content of the push message for the client in the received data.
/*
if (notify.Value is List<object>)
{
List<object> tmp = notify.Value as List<object>;
List<KeyValuePair<GXDLMSObject, int>> objects = client.ParsePushObjects((List<object>)tmp[0]);
//Remove first item because it's not needed anymore.
objects.RemoveAt(0);
//Update clock.
int Valueindex = 1;
foreach (KeyValuePair<GXDLMSObject, int> it in objects)
{
client.UpdateValue(it.Key, it.Value, tmp[Valueindex]);
++Valueindex;
//Print value
Console.WriteLine(it.Key.ObjectType + " " + it.Key.LogicalName + " " + it.Value + ":" + it.Key.GetValues()[it.Value - 1]);
}
}
*/
Console.WriteLine("Server address:" + notify.ServerAddress + " Client Address:" + notify.ClientAddress);
}
catch (Exception ex)
{
Console.WriteLine(ex.Message);
}
finally
{
notify.Clear();
}
}
}
}
}
catch (Exception ex)
{
Console.WriteLine(ex.Message);
}
}

data sent from meter-00 01 00 01 00 40 00 76 DB 08 53 55 58 31 32 39 34 38 82 00 69 20 00 00 00 01 18 50 81 C3 C9 36 49 9D 4F 0B 52 FE 2D 77 2C 95 FF 4D 34 3D 34 B3 30 F9 E2 D2 2F 3F E3 DC 09 52 3C 11 89 F0 FE 63 5D 9B 4C 10 2E AC 29 2C 78 A1 00 8E 05 85 FF 08 9F D9 73 F9 BB 6F D7 CB AF 16 EB 47 79 34 A7 4C 56 29 6A 8A 84 BF 18 0C 7F F2 26 A7 95 96 B8 31 8A E8 6B D8 BB 12 44 2A 4F 06 4E 26 A9 44

but it is not returning any data.First of all

GXReplyData data = new GXReplyData();
client.GetData(reply, data, notify);
// If all data is received.
if (notify.IsComplete)
{
reply.Clear();

notify.IsComplete is returning false.Please help out to resolve this.

Thanks in advance

Hi,

Thanks,i can able to decrypt the data now.but i have some scenario

This meter is sending around 13 parameters some meter can send more than 13 parameter also,In this scenario we need handle dynamically,but i am unable to find which value indicates what?

So,Is there any possibility to get obiscode along with data.

(I have cloned this and checking the functionality
