Hallo,
I just installed everything and the system works great.
In order to read out my PV power (parallel to grid) I ordered he AC current sensor, connected it to AUX 1 and run the Assistent.
So far OK. It's displayed on the remote console and show values (tested with a 1000W heater)
DIP setting is all off (1.5kw on 230V)
But if I turn off he load, the reading is still above 80W.
Looking in the device it shows 240V 0A biu 84W ???
How to adjust the Zero Point?
Thanks for reply

The 87W is probably what the system is using to keep itself powered (self consumption).
Also it takes about a to 2 days for the Multiplus/Quattro to calibrate the Zero point, so have you waited that long , without any changes to the assistants.
it should settle down in time
I am using Acs712 sensor to measure Ac current. But the problem is I have to adjust it's zero point after every few seconds (about 50 seconds sometimes later).
The second problem is :
I am using 5V relays. so that whenever current value crosses the limit, the relay should operate. But the problem is whenever the relay operates, the sensor values automatically get change.
I am using this code to measure the current.
