Bob,
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
Grid-Red
Grid-White
Grid-Blue
These are monitoring the 3 incoming grid lines - which can be either + or - depending on the amount of solar/battery and the load
Consumption-Red
Consumption-White
Consumption-Blue
This is always positive and reflects all the energy that is flowing into the house circuits regardless of the source (Solar, Battery or Grid)
Solar-Red
Solar-White
Solar-Blue
Theoretically always positive - except overnight when the inverters draw a small amount of power in standby mode
Battery-Red
Battery-White
Battery-Blue
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i should use the Standard Integration, the Custom integration (i believe @gregtd wrote this but it appears to be no longer maintained) or the Rest Sensors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
regards
Craig
