Fronius power meter (and inverter) - help with configuration

superkco · February 24, 2022, 3:30am

Hi all, I’m using Fronius since one year ago, but now I have started to use the HA integration. I would like to change the frequency updating consumption data to use it for my EV charger. Do you know how to change from 10 seconds to 5 seconds?

Hi !

I’m afraid this is not going to be as straight forward as you’d like. See New Fronius UI Integration with Multi Inverters - #2 by farmio and the link provided there.

If you really need more frequent updates in HA (Inverter not controlling the charger directly / via its IO port) I’d probably go for Modbus as the HTTP-API is not super fast / reliable and the Modbus people say theirs is. See Integration of a Fronius Symo Gen 24 plus Inverter via Modbus TCP

This worked for me with Gen24+BYD:

I’m in the same situation. Did you fix it? Thanks

Can you share this? I’m not familiar programming

If you really need more frequent updates you are probably better off using the Modbus integration. Integration of a Fronius Symo Gen 24 plus Inverter via Modbus TCP

I included several entities of the same device on my automation and now I’m getting very awkward values (sky high values) on the Energy dashboard (for my own dashboards I’m getting values as expected).

Does it matter to update only one sensor vs updating them all via automation?

Updating one sensor of one endpoint - power_flow, inverter, etc. - updates all entities that get data from that endpoint.

But it shouldn’t matter for the energy dashboard how frequently these are updated 🤷

Jumping on the bandwagon

Just got a FSM installed. Below is my dashboard setup

Im bloody confused as to what this is now showing me compared to my Fronius app.

farmio · March 30, 2022, 6:47am

Where is the meter installed? Grid connection path or consumption path?

cloudbr34k · March 30, 2022, 6:49am

is says meter is installed Location 0

farmio · March 30, 2022, 6:51am

That’s grid path, which is good - assuming it is correct.

Now what values don’t match to Fronius data?

cloudbr34k · March 30, 2022, 6:56am

well i was trying to delete the post as i think i figured it out

im just used to working off Power instead of energy, its just a number but in the fronius app shows this

its just understanding it better

The HA energy page is showing energy data, summed for each hour. That Fronius app screenshot is a snapshot of live power data. They are different things.

The HA energy page is showing in the lower pane the solar PV output by hour, while the top panel shows where that energy went - some of it self-consumed (orange), the balance exported to the grid (purple).

The HA Energy page animated graphic on the right with the moving dots is a bit confusing as it is showing energy totals, while the animated graphics give the impression it is power data like the Fronius app is showing.

Hello,

Newbie here. Installed Fronius via integration and local IP. The inverter is limited to 0 injection into the grid due to paperwork ongoing. No battery, just on grid system. Is this configuration OK?
Thanks!

Hi,

Is there any way to get the energy dashboard working correctly if the inverter is set in consumption path (meter_location=1)?

I’ve tried to change it to 0 but then I get wrong mettering data so I guess it has to stay set to 1.

Thanks!

See How to configure meter in Consumption path (1)? · Issue #21804 · home-assistant/home-assistant.io · GitHub
If you figured out how to do it correctly, it would be great if you contributed to the integration documentation

Changing it to 0 would not help. It is the physical position of the meter.

0 - Feed-in point, means that the meter has been installed between your utility meter and anything else inside your house. It measures what comes from the grid and what leaves your house to the grid.

1 - Consumption point, means that all your consumers on the house side of the meter, but your PV installation on the grid side of the meter. SolarWeb does the calculations according the values about produced and consumed electricity.

GSzabados · May 1, 2022, 12:28pm

Looks good! If it is a Primo, then you are absolutely good. If it is a Symo, make sure how your utility meter really counts consumption and production.
If the meter does algebraic calculation, you need to set the limitation per phase to do not produce to the grid.
If the meter does vector sum calculation, then the limitation can be set to whole system.

I believe the Fronius Smart Meter does a vector sum calculation. Your utility meter might do it differently.

Hey @GSzabados and @luixal, thanks for updating the HA documentation for the Fronius integration for consumption path-based Smart Meter’s. I have been struggling to get this functional and your above post and diagram were very useful, however with your abovementioned post and pending HA documentation update I am getting closer to resolve.

I have a Fronius Primo 5.0-1 (latest firmware 3.21.4-1) with Smart Meter 63A-1 configured within the consumption path. HA has confirmed the Meter Location is ‘1’ and I have updated the configuration.yaml and energy config with your documented changes and all appears to be working with exception of the sensor.energy_sold is not enumerating a value. i.e. Unknown.
