Smart Meter D0 Absolute Counter Values

[joba-1]

Hello Zendure,

I am a happy user of a Zendure Solarflow 800 Pro + Smart Meter D0.
Before that, I used my own IR receiver and software and got the "official" absolute counter values for consumed and produced energy in 1/10 Wh (A+, A-) and also the serial number of my smart meter. Valuable info for communicating with the energy provider.
Is it possible to include these values in the json response of the D0 bridge that currently looks like this:

wget -O- -q http://espressif/properties/report | python -m json.tool

{
    "a_aprt_power": 0,
    "b_aprt_power": 0,
    "c_aprt_power": 0,
    "deviceId": "whatever",
    "messageId": 3882,
    "meterType": 2,
    "protocolType": 72,
    "timestamp": 1757249434,
    "total_power": -43
}

That would be awsome, since it is hard to place 2 IR receivers at one smart meter ;)

Hello ,

Thank you very much for supporting Zendure and sharing your valuable feedback!
We understand how important the absolute counter values (A+, A-) and the meter serial number are for communication with your energy provider.

To better support your request, could you please provide us with the type of your smart meter, or share a photo of it?
With this information, our development team can check the D0 protocol implementation and evaluate how to include these values in the JSON response.

We really appreciate your input—it helps us improve the product and make it more useful for all users.

Best regards,
David

Sure, here is the photo of my Itron 3.HZ-BC-D4-A1-12:

In the readme of my github repo you can even find a data frame of the SML / obis message I annotated: https://github.com/joba-1/ElectricityMeter
You probably don't need that: since this frame is all that is transmitted by the device, your D0 firmware already can read and decode these original values and just calculates the power value from it. I guess all you would need to do is not throw the info away and put it in the json...
