Working on it :)

[wgumaa]

In addition, some of the sensors I used to get it to work have been made into templates. Here are some of the conversions:

` convert_grid_power:
unique_id: convert_grid_power
friendly_name: "Grid Power Watts"
value_template: "{{ states('sensor.solarnet_power_grid') | float * 1000 | round(2) }}"

convert_total_solar:
  unique_id: convert_total_solar
  friendly_name: "Total Solar Year KW"
  value_template: "{{ states('sensor.symo_advanced_15_0_3_m_1_energy_year') | float / 1000 | round(2) }}"
  
convert_power_photovoltaics:
  unique_id: convert_power_photovoltaics
  friendly_name: "Power Photovoltaics W"
  value_template: "{{ states('sensor.solarnet_power_photovoltaics') | float(0) * 1000 | round(2) }}"

  friendly_name: "House Daily Load"
  value_template: "{{ (states('sensor.daily_energy_import') | float + states('sensor.solarnet_energy_day') | float - states('sensor.convert_daily_energy_export') | float )}}" 
  unit_of_measurement: kWh

  unique_id: essential_load
  friendly_name: "Essential Load"
  value_template: "{{ (states('sensor.symo_advanced_15_0_3_m_1_ac_power') | float(0) + states('sensor.convert_grid_power') | float )}}" 
  unit_of_measurement: kWh
  
convert_daily_energy_export:
  unique_id: convert_daily_energy_export
  friendly_name: "Daily Energy Export KW"
  value_template: "{{ (states('sensor.daily_energy_export') | float / 1000) | round(2) }}"

You don't need to convert W to kW or kWh to Wh and visa versa anymore. If you have defined the correct unit of measurement and have auto_scale enabled it will calculate the conversion for you.

[slipx06]

@wgumaa I've added support for the image in 4.7.0

[wgumaa]

Thanks @slipx06. I am away for the holidays but when I get back I will finish the mapping and update you with the entities to include the fronius system.

[wgumaa]

Fronius Status Codes.xlsx

Here is the mapping I did the best I could. As you said too many codes!

[wgumaa]

So the Fronius is made up of 3 components:

1. Smart Meter TS 65A-3
2. SolarNet Data Manager
3. Symo Advanced 15.0-3-M - Inverter

Fronius Smart Meter:

SolarNet Data Manager:

Symo Advanced 15.0-3-M - Inverter

This my current view:

You can see that there are some figures that are completely off or not working:

1. Daily load
2. Not sure that the autarky value is correct
3. and the load going into the house is showing minus

[wgumaa]

Here is the latest:

I fixed the daily load but reinstating the template sensor:

house_daily_load: unique_id: house_daily_load friendly_name: "House Daily Load" value_template: "{{ (states('sensor.daily_energy_import') | float + states('sensor.solarnet_energy_day') | float - states('sensor.convert_daily_energy_export') | float )}}" unit_of_measurement: kWh

But the load going in is still wrong.

[slipx06]

The load is being calculated base on your L1 +L2 +L3 sensors.

It look like you have a sensor from the SolarNet Data Manager that you can use for Essential, namely Power Load

So try adding

essential_power: sensor.power_load <----not sure the exact name

[wgumaa]

Yes there is a sensor "sensor.solarnet_power_load" Yes but still showing a negative value. Shouldn't it be positive?

Considering that the heatpump and charger are pulling?

[wgumaa]

The last update broke the ratio and autarky

4.18.1

[slipx06]

Its working as intended. You cant have negative Autarky. Your essential load is -2.36kW which is the problem

[wgumaa]

I see that but that is calculated and I can't change that unless I make a template sensor. How have you calculated the essential load?

[wgumaa]

ok we have to figure a way to calculate the essential power. Using "sensor.power_load" is giving a negative value all the time. Is there a way to inverse that through a template?

[slipx06]

Yes you can create a template sensor that simply multiplies by -1. I don't have an option in the card to invert the load at the moment, but maybe its something I can add in the future

inverted_power_load:
  unique_id: inverter_power_load
  friendly_name: "Inverter Power Load"
  value_template: "{{ (states('sensor.power_load') | float * -1)}}" 
  unit_of_measurement: W

[slipx06]

I've added an option to invert the load power in https://github.com/slipx06/sunsynk-power-flow-card/releases/tag/v4.19.0

[wgumaa]

The Inverse essential load seems to have done the trick!

[wgumaa]

Another bug appeared: when the system is running wholly on solar - not drawing anyhting from the grid, the Autarky and Ratio show 0.

What's interesting is when I plugged the car to charge, and the export energy dropped, the Autarky and Ratio now appear:

[wgumaa]

Could be because the energy going out is negative?

I noticed it disappears as soon as it goes in KW but still there when in W

[slipx06]

Autarky only considers in your case the PV and Essential load. So there is something odd with the sensors. It wont work if your power to load is negative. The Grid power has no influence on the calculation.

[slipx06]

@wgumaa I've gone though the list of status codes and these are my suggested mappings. These moslty map to error or fault conditions. I have confirmed here https://goodhewsolar.com.au/fronius-fault-codes/

Look here also for codes

@wgumaa I see that you have both error code and status code sensors? I assume that the table above is only for the error codes and we don't really want to use that for the inverter status sensor in the card. Please can you share a link to the home assistant integration you are using so we can try figure out what the status codes mean i.e 7,2,3 etc

[wgumaa]

Sure. It's part of the core:

[cloudbr34k84]

would anyone mind sharing their Fronius card yaml code. Having a hard time figuring out where everything goes?

[wgumaa]

Sure. Give me some time. Not at home right now
