enable near realtime mode (feature request)

Issue related to

Sunsynk / mbusd Home Assistant Add-On

I ask if it's possible to add a feature to the addon timing config.
It's very usefull to have the real time consumptions when looking for failures, so in that ocassions the polling modbus times have to be the lowest possible, but it's not advisable that these values remains that way in the setup forever in order not to load the inverter, and the n the typical 30 seconds are fine.
So I ask if we can put two polling times, realtime polling, and normal polling.
And from the frontend somehow the frontend can switch that time in the addon.

Would you want to do this for only power sensors? or voltage & current as well.

Any other that makes sense?

I think power sensors are the most useful, and the less items we ask the modbus, the better for the realtime answer. Thanks kellerza.

May I ask for an explanation of the times:
Example of key ´´W´´

Read 5 seconds reads every 5 seconds from the inverter?
Report 30 seconds means that the value is updated for me in a readable form in the sensor or graph in the interface?
Change by means that if I change by 80 watts the Report time will be interrupted immediately?

If the answers are YES,
can I set the Report to a lower time for example every 5 seconds? and Change by to remove it completely.

Or is it already beyond what MQTT can handle and the edge is the mentioned 30 seconds?

What is the lowest possible read and report time?

Thank you
PS:
I have tested the HF-5111B serial network server and confirm that it is functional simply connectable via pymodbus and TCP connection
I have tested the USR-TCP232-304 RS485 and confirm that it is functional simply connectable via pymodbus and TCP connection
