Node Red : update frequency on Victron nodes

I have a Multiplus-II 5000, Cerbo GX and "tore" meter connected to the Multiplus' 3.5mm jack input.

I'm trying to use node red to turn on/off various appliances (EV charger, water heater, ...) to manage spare solar power but there is one major hiccup : measuring AC output through Victron nodes only gives me a value every 5 seconds, which is way too slow and the EV charger keeps turning itself off because it expects much faster udpates to both stay on solar charging or not trip the main breaker.

Is there any way to get a faster refresh rates on Node Red?

Would I get a much better update speed using Modbus TCP? (I'm trying to figure that one out also, but even with a Modpus polling client and the Victron excel sheet I can't seem to find where the values I want are)

Will I not get fast enough updates from the Multiplus and should I get an external energy meter?

ET112 reset Energy Bought

I have added a ET112 to my campers setup so I can measure consumed energy when on a pay connection.

What I would like to do is be able to reset the 'Energy Bought' back to zero when I hook up to a new supply. I believe this is possible through the Carlo Gavazzi UCS software but I hope to reset the ET112 counter from Node-Red over RS485.

I thought I'd ask here if anyone else has managed this so I don't re-invent the wheel.

Thanks for any help or suggestions.

Grid Meter nicht angeschlossen (meldet sich ab) - Auto Neustart möglich? NodeRed?


Bei meinem Multi 2 5000GX melden sich ab und an der Grid-Meter EM24 und ET112 ab.
Da dadurch keine Informationen zum Stromverbrauch kommen, regelt der Fronius ab und die Batterie wird nicht geladen.
Ist es irgendwie einen Automatischen Neustart anzustoßen? Vielleicht über NodeRed.

Beide Geräte sind mit einem USB Y Kabel am GX angeschlossen.

mqtt Energy Meter for 600/5 CT

Can any one advise if there is a Energy Meter available that accepts the 5A secondary for larger CT ratios 600/5 that could publish real time kw out every 1 or 2 seconds in the form of an mqtt publish.

I would like to read this value into a Venus running Node Red which is 100m away from the Energy Meter.
