ValueError Inverter State #6

mieschc · 2023-05-04T11:27:59Z

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

File "/usr/src/homeassistant/homeassistant/components/sensor/init.py", line 579, in state
numerical_value = int(value)
ValueError: invalid literal for int() with base 10: 'Input (MPP)'

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

raise ValueError(
ValueError: Sensor sensor.kostal_piko_inverter_state has device class None, state class measurement unit None and suggested precision None thus indicating it has a numeric value; however, it has the non-numeric value: Input (MPP) (<class 'str'>)

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 · 2023-05-05T20:57:25Z

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

mieschc · 2023-05-05T21:39:24Z

@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 · 2023-05-08T17:27:33Z

I do have the same issue.

2121-4 · 2023-05-16T09:38:30Z

I have the same issue.

dinomyte76 · 2023-05-16T09:47:11Z

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 · 2023-05-16T10:59:06Z

@dinomyte76
Did your fix. Seems it works again 🥇

mieschc · 2023-05-16T19:01:33Z

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

leon2908 · 2023-05-18T10:23:35Z

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

dinomyte76 · 2023-05-18T10:28:58Z

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

leon2908 · 2023-05-18T10:52:51Z

@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 · 2023-05-30T20:06:11Z

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

mieschc · 2023-05-30T20:24:21Z

@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 · 2023-05-31T17:07:18Z

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

mieschc · 2023-06-07T20:48:35Z

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

mangan62 · 2023-06-12T17:03:54Z

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

sla89 · 2023-07-21T05:13:53Z

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 · 2023-07-22T06:58:50Z

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 · 2023-07-22T09:41:04Z

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 · 2023-07-22T09:53:54Z

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 · 2023-07-22T17:58:18Z

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