ValueError Inverter State

[mieschc]

Moin Stefan,

after the core update yesterday evening Home Assistant lost connection to my Piko 20 Inverter. I had following error message in the logs:

---

Logger: homeassistant.components.sensor Source: components/sensor/init.py:583 Integration: Sensor (documentation, issues) First occurred: 10:06:34 (2 occurrences) Last logged: 10:06:34

The above exception was the direct cause of the following exception:

---

After a restart Home Assistant picked only up one updated value and stopped fetching values again.

I changed now the state class of Piko Inverter to None to fix the problem temporarly and it is working again. I now get updated values again, but the values are interuppted. See screenshots.

After change:

Before change:

Do you have any better solution for it?

I do have the same issue. A solution for this would be awesome. Loving this integration a lot and until the core update yesterday it was running like a "cat"!!!

[dinomyte76]

@mieschc May i ask where did you set the state class of Piko Inverter to None in HA? Thanks in advance!

[mieschc]

@dinomyte76 Go to folder custom components / kostal piko and open const.py. There you find the entry for the Inverter state.

As mentioned the fetching ist interupted but Energy Dashboard is still working.

[leon2908]

I do have the same issue.

[2121-4]

I have the same issue.

[dinomyte76]

I tried a bunch of things in the last days (also tried other integrations) and yesterday evening - after upgrading to latest core version - i gave this integration another try, but this time i commented the complete part of the inverter state which @mieschc suggested. It seems to work as before now. At least i do not have anymore interuptions.

[2121-4]

@dinomyte76 Did your fix. Seems it works again 🥇

[mieschc]

@dinomyte76 good idea. Did the same now and working as well.

[leon2908]

@dinomyte76 sadly still not working for me :( I commentet all your lines out but still only get one update after a restart HA.

[dinomyte76]

@leon2908 Hmm dunno. Do you see anything suspicious in your home-assistatnt.log file?

[leon2908]

@dinomyte76 I´m sorry, I only tryed to comment out the lines and after a restart of HA I saw the number only update once I shut down HA an loaded a Backup from yesterday.

[leon2908]

Any Update with the new HA Operating System 10.2 or the Core Update 2023.5.4 ?

[mieschc]

@leon2908 Looks not like Stefan ist still maintaining this Integration. I suggest to try commenting the Inverter state again. Maybe you Just missed one line last time.

[leon2908]

I give this one another go and now I get the following Error in the Log and had the same Error again.. @mieschc :(

[mieschc]

@leon2908 Sorry, I cannot help you really. I did the same like you. Did you restart Home Assistant after the change?

[mangan62]

Thanks for your work. Worked well up to version HA 2023.4 with Piko 20. after update 2023.5 the integration stopped working. Error message at Inverter State. After deleting # Inverter state and restart HA, it works again without Inverter State

Sorry folks, for some reason I do not get any notification when a new issue is created.

I will take a look at the issue in the evening and come up with a solution. Maybe you can be my testers, since I do not have this kind of Kostal inverter.

This should be the new way the sensor should be defined (according to the documentation):

    KostalPikoSensorEntityDescription(
        description=SensorEntityDescription(
            key="kostal_piko_inverter_state",
            name="Kostal PIKO Inverter State",
            device_class=None,
            state_class=SensorDeviceClass.ENUM,
            native_unit_of_measurement=None,
            icon="mdi:power-plug",
            options=[
                "Off",
                "Idle",
                "Starting",
                "Input (MPP)",
                "Input (limited)"
            ]),
        dxs_id=16780032,
        formatter=KostalPikoFormatter.format_inverter_state
    ),

if it does not work, I will release a new version with the following configuration for the inverter state sensor as it seems to work:

    KostalPikoSensorEntityDescription(
        description=SensorEntityDescription(
            key="kostal_piko_inverter_state",
            name="Kostal PIKO Inverter State",
            device_class=None,
            state_class=None,
            native_unit_of_measurement=None,
            icon="mdi:power-plug"),
        dxs_id=16780032,
        formatter=KostalPikoFormatter.format_inverter_state
    ),

BTW I have changed my mail notifications, maybe someone of you can create another dummy issue so that I can check that I receive mails for new issues now... I am so sorry guys.

[mieschc]

Moin Stefan,

unfo I am traveling abroud until October and have only limited access to my HA Installation. If I have a chance to test it, I will do, but hopefully someone else is faster.

[sla89]

I can also just release a new version that does what is mentioned here as the working solution. I will go for that approach.

[sla89]

I have just release a new version with the fix. Please give it another try - I hope it solves your issues. Otherwise feel free to open the bug again. :) Thanks to @mieschc for providing the fix and testing my email notification settings 👯

Thanks. the second option works. the first gives an error: ValueError: Sensor sensor.kostal_piko_inverter_state is providing enum options, but is missing the enum device clas have a nice weekend

[sla89]

The second option is part of the latest release. Thank you for testing
