House Load

[gjhill6100]

Hi,

What is the correct sensor to monitor to show actual current house load ?

I have a H1-5 and also a S2500 which is monitored using CT2 Meter in to the H1-5.

If I try to use Load Power, then this does not give the correct current house load power

Thanks

So the H1 and the S2500 are in parallel, both feeding energy into the house?

I suspect you'll need to create a template sensor which calculates your load as the power which both inverters are outputting minus the power going to the grid, ie Inverter Power + CT2 - Grid CT.

Actually, since load should just be Inverter Power - Grid CT, you should be able to do Load + CT2?

I use load_power + ct2_meter.
I've got an AC1 plus a separate solar inverter.

This is my template sensor

'- name: "PV Power"
unique_id: pv_power
unit_of_measurement: 'kW'
device_class: power
state: >
{{ [0, (states('sensor.ct2_meter') | float(default=0) * 1)]|max }}'

'- name: "House Load Power"
unique_id: house-load-power
unit_of_measurement: 'kW'
device_class: power
state: >
{% set load = states('sensor.load_power') | float(default=0) %}
{% set pv = states('sensor.pv_power') | float(default=0) %}
{% set power = ( load + pv ) %}
{{ "{:.3f}".format(power) }}'
