Power Consumption Using Solar Panel's Smart Meter

Hardware
1

Hi, newbie here and would appreciate some assistance.

I am getting solar installed at my house and have been looking at the GoodWe inverter as it is cost effective and appears to have decent integration with HASS.

To also track and manage the power consumption of the whole house, I have been recommended the “GoodWe 1P Smart Meter” which supposedly integrates into the inverter and is trackable through the native app.

Does anyone have experience with this smart meter or smart meters for other solar inverters that can comment on how that data can be integrated into HASS?

There is some information on supported models here:

I have sunpower panels with micro-inverters on each panel. I have a sunpower pvs6 and a tesla powerwall. I take everything for HA from the powerwall. I created utility meters for each flow direction and use hacs Power flow card. I have this on my home page:

I bastardized the card to do energy as well as power. I just couldn’t fix the units. I created an energy page to display my utility meters and record the data.

I also use the energy page.

I would like to control more of the Tesla API but haven’t figured out how to do it. I would like to prevent pulling from the grid from 4-8 pm as my utility assess demand charges. The tesla app is not feature rich enough to do this.

If you would like to see configuration on the meters and energy page I will be glad to share.

I would also recommend Powercalc (hacs) for calculating things you don’t have power monitors on.

I also have two shell 1 em monitoring four circuits. AC condensers and furnaces.

Hope this shows you some of the potential.

Thanks @tom_l, I’ve read through that page but it doesn’t specify anything to do with actual power consumption or working with an integrated smart meter

Thanks @AllHailJ, nice to see the potential. Just trying to see if anyone has had success with extracting data from the GoodWe smart power meter, which I suspect wouldn’t be as well supported as Tesla’s powerwall.

You mean other than the picture from that page I included that specifically mentions which models are best for using with the energy dashboard?

Also regarding this:

I can tell you than the SMA meter is expensive and not very accurate.

The Shelly EM is pretty good for the price.

Yeah, so the only model that appears to be available where I live is the D/NS model, however what I’m trying to understand is not how to get data from the inverter, but from the smart meter that is an additional component to the inverter.

Unfortunately that isn’t covered on that page (or anywhere else I’ve been able to find).

Thanks for the comment on the SMA meter, it makes me suspect the GoodWe one probably isn’t worth the cost.
I’ve had a look into other solutions people have used (especially in Western Australia where I’m from), however no one seems to have mentioned reading data from an integrated smart meter.

Hey, how to make a power flow panel?

it is automatically created when you fill in the configuration for the energy dashboard.

I’ve been investigating this too and I think I’ve cracked the issue (that I was falling into too): The Goodwe Smart Meter doesn’t have any communication channel to users. It’s only comms is RS485 to the inverter. I’m pretty sure their Smart Meters are useless without one of their Inverters.

So I think it should just show up as extra data in the data output by the Inverter.

Which I think means I should be able to make it work if it doesn’t already do so.
