Activate/Set Schduled Charging via Modbus

Hello!

Is it possible to enable and change the "Scheduled Charging" feature in ESS via modbus or other remote interface?

I am using awattar.de as Energy Provider and i want to charge my battry wht the energy price is on lowest state.

Thanks

Dennis

Consulting the Modbus TCP register list, unfortunately, there are no registers to address Scheduled charging.

Any other idea to remote enable or set it? Maybe with Relay? Or MQTT?

Because i cannot find any information, it seems there is no possibility.

i'm also looking for this feature, It would be nice if Victron can develop it. Or is there any other way to programmatically configure these settings ?

You can use mqtt to get and set the actual settings -> processing could be made via node-red or other automation systems.

For instance:

N/*************/system/0/Control/ScheduledCharge,0

N/*************/settings/0/Settings/CGwacs/BatteryLife/Schedule/Charge/0/Day,-1
N/*************/settings/0/Settings/CGwacs/BatteryLife/Schedule/Charge/0/Duration,0
N/*************/settings/0/Settings/CGwacs/BatteryLife/Schedule/Charge/0/Soc,100
N/*************/settings/0/Settings/CGwacs/BatteryLife/Schedule/Charge/0/Start,0
N/*************/settings/0/Settings/CGwacs/BatteryLife/Schedule/Charge/1/Day,-1
N/*************/settings/0/Settings/CGwacs/BatteryLife/Schedule/Charge/1/Duration,0
N/*************/settings/0/Settings/CGwacs/BatteryLife/Schedule/Charge/1/Soc,100
N/*************/settings/0/Settings/CGwacs/BatteryLife/Schedule/Charge/1/Start,0
N/*************/settings/0/Settings/CGwacs/BatteryLife/Schedule/Charge/2/Day,-1
N/*************/settings/0/Settings/CGwacs/BatteryLife/Schedule/Charge/2/Duration,0
N/*************/settings/0/Settings/CGwacs/BatteryLife/Schedule/Charge/2/Soc,100
N/*************/settings/0/Settings/CGwacs/BatteryLife/Schedule/Charge/2/Start,0
N/*************/settings/0/Settings/CGwacs/BatteryLife/Schedule/Charge/3/Day,-1
N/*************/settings/0/Settings/CGwacs/BatteryLife/Schedule/Charge/3/Duration,0
N/*************/settings/0/Settings/CGwacs/BatteryLife/Schedule/Charge/3/Soc,100
N/*************/settings/0/Settings/CGwacs/BatteryLife/Schedule/Charge/3/Start,0
N/*************/settings/0/Settings/CGwacs/BatteryLife/Schedule/Charge/4/Day,-1
N/*************/settings/0/Settings/CGwacs/BatteryLife/Schedule/Charge/4/Duration,0
N/*************/settings/0/Settings/CGwacs/BatteryLife/Schedule/Charge/4/Soc,100
N/*************/settings/0/Settings/CGwacs/BatteryLife/Schedule/Charge/4/Start,0

I am not using scheduled charging, so my values are default.

still no having any Modbus TCP register to handle that, finally I'm doing that with an SSH connection with PowerShell. Works well
