Working on it :)

wgumaa commented 8 months ago

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:

  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"

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 commented 8 months ago

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

wgumaa commented 8 months ago

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 commented 5 months ago

Fronius Status Codes.xlsx

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

wgumaa commented 5 months ago

So the Fronius is made up of 3 components:

Smart Meter TS 65A-3
SolarNet Data Manager
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:

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

wgumaa commented 5 months ago

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 commented 5 months ago

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 commented 5 months ago

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 commented 5 months ago

The last update broke the ratio and autarky

4.18.1

slipx06 commented 5 months ago

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

wgumaa commented 5 months ago

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 commented 5 months ago

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 commented 5 months ago

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 commented 5 months ago

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 commented 5 months ago

The Inverse essential load seems to have done the trick!

wgumaa commented 5 months ago

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 commented 5 months ago

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 commented 5 months ago

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 commented 4 months ago

@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/ I'm not seeing many "normal" or "standby" states. Can you check
