Currently i use Node Red with the Rest/query interface to automate all of my home stuff - but as i am useless as Interface design - my dashboard looks like crap.
I have decided to have another plunge into HA now that they have fancy energy dashboard and have a couple of questions
My setup is as follows - in Australia 3 phase
Main meter board - this is where the Grid enters the premises and where the Solar and Battery are also connected - i have a single IOTAWATT in here and this is what i will be focusing on for the sake of this exercise
Switchboard - this houses all my circuits in the house and is where all the load for the house derives from
In the main meter board - i have a single Voltage reference (using the Jaycar suggested unit ) - this is monitoring my red phase (L1) and deriving the voltage for the other two phases (all 3 phases are within 3 volts of each other the majority of the time)
In this same meterboard i have deployed the following CTs
These are monitoring the 3 incoming grid lines - which can be either + or - depending on the amount of solar/battery and the load
This is always positive and reflects all the energy that is flowing into the house circuits regardless of the source (Solar, Battery or Grid)
Theoretically always positive - except overnight when the inverters draw a small amount of power in standby mode
Can be iether + or - depending on whether i am charging or discharging the batteries
Now i have followed most of the threads on here and on the HA forums about this and am up in the air about whether i should use the Standard Integration, the Custom integration (i believe @gregtd wrote this but it appears to be no longer maintained) or the Rest Sensors
Do you have opinions on the best way to go with this ?
I assume regardless of the method i will have to adjust my outputs through integrators on the IOTAWATT so ensure i have both a + and - flow to my batteries
