Is that a thing, DSMR5.1? Is that printed on your meter? Is it for Dutch or Belgian meter?

The specification from "netbeheerdernederland" goes up to 5.0.2: https://www.netbeheernederland.nl/dossiers/slimme-meter-15/documenten

Hi Rob, good question. sagemcom.com tells me that it actually is. It's dutch meter, installed last February if i'm not mistaken. What else do you need?

Thanks, Hans

RobBie1221 commented 3 years ago

Maybe a bit obvious, but are you sure the port is correct? It's not able to parse data, which points to an issue with the serial configuration (baudrate, bytesize, stopbits).

According to this: http://domoticx.com/p1-poort-slimme-meter-hardware/ The settings for DSMR5.0 comply with T210-D (115200/8/1), so at least it should be able to parse data, which it can't.

I would say, either port is wrong, settings for serial connection are wrong or your cable is not working. For the last one, what are you using?

Thanks, the portnumber was set wrong and now i'm getting values.
