Hi all, I have a following setup: Multiplus II managed by a raspberry PI, connected to the battery (JK BMS) no solar. I am using a “virtual” mqtt based grid sensor which is visible and recognised by the system. The issue is that the refresh rate of the sensor is 10s, which means that with ESS set i…

You should try using the custom control /Hub4/L1/AcPowerSetpoint instead of Venus settings Grid set-point. /Settings/CGwacs/AcPowerSetPoint . [afbeelding] [afbeelding] (Currently my system is in mode-2)

I kind of managed to obtain what I want when setting the ESS in mode Battery Optimized with [image] Where the calculate gridpointset is let currentSet = parseFloat(context.get("currentSetPoint")) || 0 let gridPower = parseFloat(msg.payload); let newCurrentSet = currentSet - gridPower; node.warn(…

If you only want to control the grid setpoint, use mode 2 and let the system handle all the other values. With ESS Mode 3, the grid setpoint has no impact, because the multiplus is no longer adjusting it’s output based on that. You then have to provide a explicit InverterPowerSetpoint for the Inver…

Sooo the documentation ( ESS mode 2 and 3 [Victron Energy] ) is completely wrong? 3.3 paragraph states that When controlling the Multi using software running on the GX device, you should set Settings→ESS→Mode to external control. The following dbus paths can then be adjusted on the com.victronenergy.…

I think the documentation is correct but the catch is “setpoint for Lx” is in reference to the inverter and NOT to an external grid-meter or even the meter of the inverter itself. This is explained in 3.1. So setpoint -100 on L1, will make your inverter provide 100W. If your consumption is 200W, yo…

the whole logic behind ess is weird. I got it to work in a mode 1&2 by removing the external grid sensor (mqtt based) and setting “grid metering” to inverter/charger. [image] [image] In this mode ESS do more or less what I want it to do, but I need to bear with the built in smoothing algorithm w…

This works on mine [ { "id": "6b4e02d041c66f30", "type": "tab", "label": "Manual Automation", "disabled": false, "info": "", "env": [] }, { "id": "cd1e6f25932e95b7", "type": "victron-input-ess", "z": "6b4e02d041c66f…

In mode 3, how often did you push the setpoint to the inverter? If it doesn’t receive any setpoint for a minute (if I recall), it switches back to idle. Inverter/charger metering works “instantly” if you have all your loads on the AC-out side of the multiplus and the grid on the AC-in side. (Both n…

Yeah, only AC in due to being parallel install, so no luck there (given where the MP is it would be pretty complicated to wire it differently). I have been trying to push a constant -500 as well via a simple 1second timestamp but no luck. Even now for the sake of a test I set disabled my current f…

flows.txt (31.2 KB) [image] flow as a text file I use this to force my system to export before battery fully charged -50w is nearly zero on my system, i do have 2x MP2 in parallel

David solution didnt work (same results as my tries out). [image] @snowwie :folded_hands: that worked. I swear I tried it in the past but probably due to some combination with external sensor it was not working as expected. Thanks you!
