Import Smart Meter ISKRA MT681 SML vzlogger

[lazaruss72]

Hello,

is there anyone here who has managed to read ISKRA's smart electricity meter MT681 and display it in Domoticz?
I despair meanwhile. I think I have read 3/4 of the entire internet.
The meter has an optical interface (9600bd, 8N1) which sends a SML message every second.
This interface is read with an IR-Write/Read head
To analyze these SML messages there is a software project called Volkszähler (vzlogger). With this I managed to display the different data (OBIS codes).

Is there any way to process this SML message in Domoticz direct? Similar to the P1 Smart Meter or S0 Pulse Counter Meter?

Or does anybody know a way to import the data from these vzloggers into Domoticz?

In the vzlogger software there is an API with which values can be queried. But I can't get them sent to a virtual sensor.
I can imagine that I can get the values in a script and update the sensors with them. But I have no idea how to do that. I do not have the knowledge.

I would be very happy if someone in the big Domoticz community could help me.

Best regards
Marco

Is this github-content useful?
Seems to describe a translation between the SML-logging and Domoticz.

Hello,

this is a very interesting approach.
But i don't know how to get the data into domoticz (the last step)

If correctly understanding this german discussion, this solution is more or less equivalent to the output-side of the SMLogger in the picture in the previous message: https://www.photovoltaikforum.com/threa ... ost2141994
But as a participant, you are already involved.
And they are right, that MQTT is already a direct port to Domoticz:
you just have to make the suitable link for transition .........
