Modbus Multi RS ESS minimum SoC setting address?

I’m trying to read and control ESS Minimum SoC over Modbus.

The address is 2901 on ID100. This is for the Cerbo, I can change the value over Modbus, and the value readout over Modbus is changed accordingly, but it does not affect the running ESS.

The ESS in a Multi RS setup is managed by the Multi RS, not the Cerbo, but I can’t find any address for this setting in this setup.

Not available jet?

(2903 is more important to me, but for troubleshooting is 2901 more convenient…)

I think ID100 is generic system. But you need com.victronenergy.multi

Thank you!

That works indeed! I hadn’t read through the register list sufficiently.
The value comparable to 2903, which I need, is com.victronenergy.acsystem address 4925.
