I am currently using a EM24 as a Grid connected meter ( actually an SMA EM made to look like a EM24 via software in Venus GX v2.66) and would like to add an ET112 to measure output from my non compatible SMA inverter . Do I have to change any settings on the EM 24 - addresses to get the two to work together?
I'm using two ET340 3 phase energy meters on the one RS485 bus, USB into Cerbo or Venus GX, by using windows software from Calo Gavazzi UCS7 to change the default bus address on one of the meters to 2. (use the same cable connecting into the Cerbo GX, just connect into windows computer USB port, while plugging only the energy meter you need to change the address of).
Using a second energy meter is not supported by Victron unfortunately, while Victron Connect then displays the energy meters readings including kWh acclimated, data stored and displayed in VRM is limited and the graphics are inaccurate. VRM also confuses the Grid or Load state of the meters which is understandable using 3 phase energy meters on single phase.
Having said all this I still find it useful even in the unsupported configuration as remote raw data is still available to be viewed. Maybe one-day VRM may support anything but the most basic energy meter configuration.
If you on single phase what are the other two phases measuring - specific loads ?
