Fronius Integration into Energy dashboard

Hello,

I had succesfully configured (basic) by fronius integration but I cannot find the current usage sensors in the Energy sessting.

Help!! I have the same problem!

The meter device id should be “0” in most cases. It would also have been the default.

If you have a meter you should probably turn off night-shutdown in the inverters preferences - otherwise no consumption data can be read.

6

I think device ID “1” is fine as I get the data and check it.

So you don’t have the Fronius SmartMeter installed?
What do you get for http://solar.homeland.local/solar_api/v1/GetMeterRealtimeData.cgi?Scope=System ?

In your templates you are mixing up energy and power everywhere (Unit, device_class, name, …).

That’s unfortunate. Fronius doesn’t seem to report energy data when using an S0 meter. You’ll have to use the Riemann sum integration integration to calculate energy from power.

Hallo Toboli,

danke fĂźr deine Informationen!
Ich besitze einen Fronius Gen24 Wechselrichter und eine BYD Batterie.
Die angezeigten Werte stimmen nicht mit den vom WEB Interface des Wechselrichter zusammen.

Meine Konfig sieht derzeit so aus.

Hi!
This is very unreadable. Try editing your post and put yaml in code-blocks (tripple backticks `)

Make sure your Gen24 inverter runs the latest firmware. I think last week 1.13 was released - it fixes some bugs with the API.

Hallo, de Wechselrichter läuft mit der letzten Firmware 1.13…
Den Code habe ich nochmals, nun hoffentlich richtig, angefĂźgt.

Doesn’t a Gen24 inverter with 1.13 provide energy entities by default (without having to use Riemann sum integration)?

Hallo Franz

Ich habe anscheinend die gleiche Hardwarekonfiguration wie du. Ist es dir gelungen den Fronius in das Home Assistant Energy Board einzubinden?

Hi, I have tried to use your config with my Fronius Symo Hybrid, so far it looks good, only that in the Energy Dashboard is reporting the power I am using from my Battery as consumption from the grid.
See screenshot below, maybe there is a solution for it. Did you manage to set it up correctly?

So the consumption from the Grid seems to be wrong, as it shows the same mount I am using from the battery.

17

Hallo, leider bin ich auch noch nicht weiter gekommen.

18

@farmio First of all, thanks for providing the New Fronius Integration. My Fronius is a Gen24 with Firmware 1.14.1. In the Documentation you mention that we should use a Riemann Sum for adding a Battery to the Energy-Dashboard. Do you have an example? I can’t get my head around for Integrating my Battery.

Thanks
Lukas

have a look some posts above: Fronius Integration into Energy dashboard - #13 by almtaler

This looks quite promising, apart from the entity names - which are used twice for grid and battery (grid_import_power and grid_export_power) - but you should only need the battery ones anyway. So I guess (copied untested as I don’t have a battery myself):

sensor:
  - platform: template
    sensors:
      battery_discharge_power:
        device_class: power
        friendly_name: "Batterie entladen"
        unit_of_measurement: "W"
        value_template: "{{ max(0, states('sensor.power_battery_fronius_power_flow_0_http_192_168_99_1') | float) }}"

      battery_charge_power:
        device_class: power
        friendly_name: "Batterie laden"
        unit_of_measurement: "W"
        value_template: "{{ max(0, 0 - states('sensor.power_battery_fronius_power_flow_0_http_192_168_99_1') | float) }}"
        
  - platform: integration
    source: sensor.battery_charge_power
    name: Batterie geladen
    unit_prefix: k
    round: 2

  - platform: integration
    source: sensor.battery_discharge_power
    name: Batterie entladen
    unit_prefix: k
    round: 2

Just try it and let me know if it works :man_shrugging:

Looks promising.
I’ll let it run for a few days and check the values and will come back with a result.
