I've wanted maximum control with my devices for creating tools that will automatically configure your system, etc. (I am a developer)
With CCGX and Modbus-TCP can you say change the maximum current for your charge controller? Or with the new MPPT update, change the re-bulk / absorption / float voltage?
If it can't I would rather stick to VE.Direct and sniff the serial data since the VictronConnect allows you to do so.
Hi, ModbusTCP only allows for reading and writing operational values, not configuration.
You’re indeed better off with vedirect for this.
Fyi we ll also update the vedirect documentation; a few weeks from now.
That's actually awesome news. I was pretty worried when I was told that it was no longer supported.
Perhaps some message got a bit transformed in its way to you.
For many situations, ModbusTCP is the better choice. So indeed we actively encourage people to check that out first. Before trying and work with our proprietary protocols.
Anyway; have a good weekend!
There are only certain Modbus registers that are writeable.
