Read com.victronenergy.vebus all Enegry register has value 0

Hi,

I would like to have an overview using modbus of kwh charged from and send to the grid but when reading this registers they are all 0. (using a cerbo GX)

Energy from AC-In 1 to AC-out	74
Energy from AC-In 1 to battery	76
Energy from AC-In 2 to AC-out	78
Energy from AC-In 2 to battery	80
Energy from AC-out to AC-in 1 (reverse fed PV)	82
Energy from AC-out to AC-in 2 (reverse fed PV)	84
Energy from battery to AC-in 1	86
Energy from battery to AC-in 2	88
Energy from battery to AC-out	90

using the battery registers

Discharged Energy	301
Charged Energy	302

is not an option since i am using a can.bus connected BMS battery.

what are the other options ?

Thanks,

Ceke

Hi everyone,

Found the issue, in case someone else have the same :

I was reading the register as a signle register. It returned only the first part of the register what was equal to zero, reading the second part gives me the right output.

The relevant scale factors are indicated in Victron's modbus spreadsheet.
