I am building a grid tied system with a MPII 5k. As a grid meter I am using an EM540. For now I have only set up the Cerbo GX, the grid meter and 2 Ruuvi sensors to play around en test some stuff.
Al works nice at this moment but I'd like to have more data from the grid meter. In NodeRed I can see al the default data but that is only about half the parameters the EM540 measures. For instance, it would be interesting to keep track of the actual Apparent Power and Power Factor With all the SMPS's around the house, an that number still growing, the PF will be worsening.
Same for the DMD (max power demand over the last 15 minutes). In Belgium this value is one of the variables that makes up your electricity bill.
These values are not in the drop-down menu for the grid meter but are clearly described in the protocol manual from Carlo Gavazzi.
How do I make these measurements visible in my system?
