Changing setpoint in Cerbo/VRM does not work

Q&A and troubleshooting

I recently have updated the firmware of my MultiPlus II from 506 to 556. Since then the MultiPlus II (3x in a 3-phase solution) do not respond to changes of the setpoint (ESS setting grid setpoint). Both positive (charging battery from grid) and negative (feed-in energy to grid) values are shown in the ESS settings but ignored, so no charging and no feed-in. Also negative values from a remote application (Home Assistant) with modbus/tcp register 2700/2716 are not accepted by the Cerbo and/or VRM. With v.506 it was allright. Any idea anyone?

Regards, Bert

Did you save your MP data and assistants before updating and restored them after ?

Thanks for your response. I re-configured all 3 MultiPlus II and installed the ESS assistants again with VictronConnect and VE.Configure after the installation of the new firmware. I had to because 1 MP (L2) was replaced with a new one.
