Is it not possible to use multiple energy meters (ET112) on one CCGX?

We are trying to measure the energy consumption of individual air conditioners, using one ET112 for each and collecting the data through a CCGX but we only get one displaying. Is this not possible?

I have more than one energy meter in my system. One is assigned to measure grid, the other is assigned to measure PV power. Some people have three meters if they have PV on either side of the Multi / Quattro.

Did you make sure that the meters have different MODBUS ID's or is each one on it's own RS485 - USB interface?

They are all on separate RS485-USB cables via a USB hub to the CCGX.

Do you see the input from each ET112 on the screen? I would imagine the maximum is 3 (if you assign 1 to mains/genset, 1 to PV and 1 to load)?

Does anyone have more ideas around this? We have the ET on one Victron RS485 to USB cable each - connected to a USB hub and then to the CCGX.
