Hello,
perhaps I'm more lucky here (Question also in Questions & Answers):
For a control with iobroker I need the value of the "active SOC limit" which is displayed in the ESS section of VenusGX. Unfortunately, I cannot find the parameter as Modbus TCP register in the Excel table.
Is there a way to add a register?
Thanks!
Found the wanted parameter as dbus-path in
https://github.com/victronenergy/venus/wiki/dbus :
/Settings/CGwacs/BatteryLife/SocLimit <- Output of the BatteryLife algorithm (read only)
So i hope there is a way to read it with modbustcp.
I'm not a programmer so i dont want do manipulate the Venus GX.
Even there seems to be a description at:
https://github.com/victronenergy/dbus_modbustcp
No idea?
Is there a way to request it for the next Venus firmware?
Hi, I use ioBroker too.
It is register 2901
Thanks for your answers.
I have already experimented with register 2901. If the SOC limit is limited by the ESS, the calculated value of the energy content of my battery is not correct. (I'm using a BYD Battery Box LV 7.0)
I think the value for active SOC limit is dynamic, ESS minimum SOC is a static setting. I want to calculate the energy (kWh) that is released for use depending on the last SOC history in the ESS. This can sometimes be less than the calculation with an ESS-Minimum SOC value.
I would be grateful if the value becomes available with a future version of the VenusGX firmware.
I have been wondering this too, would like to have Home Assistant logging this for graphs.
