total_charging_energy and total_discharging_energy not working for Marstek Venus E3.0

[Flautz]

The values for total_charging_energy and total_discharging_energy are always zero. A manual read of the Modbus registers using mbpoll gives the same values. Apparently, the register addresses are wrong for the Venus E 3.0.

total_charging_energy:
    register: 33000
    count: 2
    scale: 0.01
    unit: kWh
    device_class: energy
    state_class: total_increasing
    enabled_by_default: true
    data_type: uint32
    precision: 2
    scan_interval: low
total_discharging_energy:
    register: 33002
    count: 2
    scale: 0.01
    unit: kWh
    device_class: energy
    state_class: total_increasing
    enabled_by_default: true
    data_type: int32
    precision: 2
    scan_interval: low

What firmware are you on?

Some only work from EMS version 146

My battery has been in operation for a few days. I have a similar problem, and my "total_charging_energy" and "total_discharging_energy" values ​​aren't changing; they remain constant at 7.56 kWh and 5.15 kWh, respectively. My Venus E 3.0 is running firmware version V144. An update via the app isn't possible. How can I update the firmware if that would solve the problem?

[Flautz]

Same issue. I am running 144 firmware and there is no update available.

[fonske]

Ask for an update through Marstek App feedback
146 has these missing values.

[Schrolli91]

Yes this is a known Bug in the Firmware and you have to contact the Support of Marstek to get the update.

I now asked the support twice, no answer for days. Anyone lucky with getting that new firmware version? If so, what did you asked for?

Same here...

Very well known, sometimes they respond quickly sometimes it takes weeks

FYI: My ticket is still open at Marstek, but EMS version 148 was released today. It solved the issue.

Nice, thanks for the feedback
