Grid Setpoint access destroys flash-cells?

Q&A and troubleshooting

Hello,
I intend to use Node Red to control Grid Setpoint to manage the feed in of excess power back to the grid.
Victron notes here: ESS mode 2 and 3 [Victron Energy] in chapter 2.1 the difference between two types of registers to avoid wearing the flash based memory in the GX. Can I assume that Node Red is accessing automatically registers 2716 and 2717 which should be save even in case of a very high change rate for Grid Setpoint? I’m using the node “ESS Control / Venus settings / Grid set-point (W)”. Is there generally a way to see which register is accessed in a specific node?
System set-up:
Gateway: Cerbo GX (v3.54)
Inverter: 1x Multiplus-II 48/5000
Battery: 3x Pylontech 3000
Solar Charger: Third party MPPT VS120
Battery Monitor: Pylontech BMS
Energy Meter: VM-3P75CT

Thanks, Christian

Hi @SoliB

I’m curious about this also as it has been a concern I’ve ran into in the past.

I’ll try test it out when i get home. ie write to registers and monitor node red and gridsetpoint per gx and see what happens when each register is used.

Dear Community,
Are there any ideas regarding the register addresses accessed in Node Red?
Do you have experiences with frequently changing setpoint register values in Node Red, is this risky for the Cerbo-GX HW or not?
Many thanks in advance, Christian
