Using a power meter (sml) with openHAB

I’m no developer and I don’t know the SML-protocol, but I (think I) understand: the code from the dailab reads the SML output and transforms it in seperate ASCII-lines for every entity, that’s found in the stream. Therefore I assume, the hex-code you see with mincom doesn’t include the additional information also.

That’s why, I suggested talking to your electricion, if your power meter is basically capable of giving out that information, and perhaps only has to be configured to do so in the first place. If he says, it should append those information also, and it’s still not coming through, you’ll have to analyze the output. My examples relies on the information, which is coming from libsml. So, if the power meter should also include the addititional fields, you have to get in touch with the dailab developers, if there’s a possibility to get that into libsml also.
