I’ve just seen this thread regarding Fronius solar inverters and thought that since the API is available and a few people have integrated in various ways, it would be nice to have a proper core HA component for these. These solar inverters seem to be quite popular so I’d imagine plenty of people would end up using the component.
There are some other links I found if it helps in any way.
The component that was started by @nielstron has been merged in the dev branch of HA. I tried it today but couldn’t get it going. I did also try the CC from @safepay which works. I think it would benefit the community if that now official component would be used and tested to iron out any problems.
As soon as I get that one working I will start using that.
I’m using this custom component and it is working perfectly. I’m no programmer but wondering if maybe this should have been the core version instead of what is now coming out in v0.96
Big thanks to @safepay for your work mate, much appreciated. (now I just need to sort out a monitor for power usage…)
One issue I have discovered is that if I restart HA while the inverter is offline (at night) then the component fails to load:

which leaves me with:
I’m just waiting for the sun to come up so I can restart HA again to make sure it comes back to life, but it would be nice if this didn’t happen. Unfortunately I can’t help, only report
@safepay After struggling with why I could not get the core integration working I found this post (which talks about a couple of custom components that are working) so I decided to give one a try…works without any problems…Thanks for your work!
@safepayJust an update and a question. The component has proven to be excellent over the past 24 hours and I have been busy today connecting a fronius smart meter. That went well and connected very easily and quickly detected by the inverter. My question is as I already had the three extra sensors for the smart meter in my config (initially they did not appear which I thought was nifty) I was expecting that after the smart meter was connected and I restarted HA they would appear…sadly after several restarts they have not appeared.
I know the meter is working because I now see extra information both on the local IP application and the solarweb application.
Any ideas what to try in HA?
Here is my config:
- platform: fronius_inverter
ip_address: 192.168.1.181
monitored_conditions:
- ac_power
- day_energy
- year_energy
- total_energy
- ac_current
- ac_voltage
- ac_frequency
- dc_current
- dc_voltage ### all the above are working
- grid_usage ### these are the three that are not appearing in the /developer-tools/state
- house_load
- panel_status
This component has been working perfectly however I am noticing (not sure exactly when it started) that the values for Year Energy and Total Energy seem to be incorrect… I don’t think my system has generated the below figures somehow!
I am also using the Fronius compnent, works great, thanks to @safepay
Just one question I have regarding the polling interval. Can it be changed somehow to get faster updates?
Currently it looks like it updates the figures every 60 secs, I would like to change that to like 10 secs or so.

@safepay I have been using your Fronius Component for over 4 months now and its fantastic. I just updated to the latest release from https://github.com/safepay/sensor.fronius as I noticed you had made an update 19 days ago and I had noticed the below error when I was trying to remove all the errors under 0.107.7
020-04-18 04:02:54 ERROR (MainThread) [homeassistant.core] Error doing job: Task exception was never retrieved
Traceback (most recent call last):
File "/usr/src/homeassistant/homeassistant/helpers/entity_platform.py", line 425, in _async_add_entity
raise HomeAssistantError(msg)
homeassistant.exceptions.HomeAssistantError: Entity id already exists: sensor.fronius_ac_power. Platform fronius_inverter does not generate unique ID
Although there is this error I cannot fault the way the component is working?
Any ideas whats the cause of this?
Cheers again and this nothing urgent as outwardly the component is working well at the moment.
Just updated to 109 and get the below error in the logs
Detected I/O inside the event loop. This is causing stability issues. Please report issue to the custom component author for fronius_inverter doing I/O at custom_components/fronius_inverter/sensor.py, line 325: result = requests.get(self._build_url(), timeout=10).json()
