I’m discovering a solution for observing voltage and current measurements across our multistory house
We have 4 sections with two separate power inputs each
Each power input is a three phase line 220V/380V
Each sections consist of about 100 apartments and we have 400A fuses on each phase
In each electrical panel room I have uninterruptible power supply and a wifi/ethernet connection
I need a budget solution which will give me a visibility of the state of each line - current voltage on each phase. I do not need high precision, just the visibility if everything is ok, or some phase has burn off, or the entire line is out. As a bonus - some charts of power consumption.
I would avoid any classic Ampere-meters passing through themselves all the possible 400A - it would be very expensive and I do not want to cut into lines
I’m looking into Hall effect sensors which seems optimal for me. And I struggle with how I should gather measurements from 6 sensors in each section of the house and dump them to HA
Would appreciate if anyone share similar experience or just give me a hint what to look at
