I suggest use Virtual Devices. This application will allow you to monitor individual parameters of the inverter on one screen.

Virtual Devices

Here is guide how to setup it:

Hello!

I am trying to my Goodwe inverter but get an error:

measure_battery OutOfRangeError: 400 is greater than 100 (out_of_range)

What to do?

Michal_Stranik · August 20, 2022, 7:31pm

Hi, could you write me email to mistradev@gmail.com? If you will agree to share temporary your data, I will check why this is happening.

Hi! Thanks for the app! Really nice!
How often does it poll for new numbers?
Thanks.

Michal_Stranik · September 2, 2022, 10:00am

@Lintin Default interval is 5 minutes, inverter also report only every 5 minutes, so it doesn´t make sense poll more often.

Hi,

since this morning the app throws this error

{“'language”:“en”“function”:
['ADD"“UNBIND”|, hasError":true’msg"“T
,
““code”:“innerexception”“data”:”; comp onents”:
('para":“{'model":{'PowerStationld": 'xxxxxxxxxxxxxxxxx}”“langVer”:1 53 “timeSpan”:3131 6,'api":“http://eu.semsportal.com:82/api/v2/PowerStation/GetMonitorDetailByPowerstationld”
… }

When I restart the app the error shortly disappears, but then (I assume after using api to get the data the first time) the error is shown again (red sign with ! Next to the goodwe device).

Anyone else experiencing this issue?

Thorpedo · September 13, 2022, 10:55am

Suddenly the error disappeared. Seems to have been a problem on sems/goodwe site!

rikadoo · September 13, 2022, 5:34pm

@Michal_Stranik Is this problem fixed? I got the same issue.

Thorpedo · September 13, 2022, 5:59pm

Around midday CEST the error didn’t appear again after I restarted the app.

As I didn’t recognize any app update, I think the issue has been on sems/goodwe site. In parallel i tried to install another solar app which also connects with goodwe. I wasn’t able to do so at that time. I just tried a moment ago and it works now.

Michal_Stranik · September 13, 2022, 9:24pm

Hi @Thorpedo @rikadoo , sorry, but I can´t fix something, what is not broken : )
It seems to be problem of Goodwe, their API is not reliable. I suggest contact their support.
When I contacted them some time ago, they wrote me, they can´t/won´t help me with API, so there is nothing I can do about these fails. App I made just use their API and if it fails …

rikadoo · September 15, 2022, 3:14pm

Thanks for the reply, well then this app is useless for me I will follow this app, maybe in the future when GoodWe fixed his API i will be usefull.

Thanks for the work!

Michal_Stranik · September 15, 2022, 9:56pm

It is interesting, that app works on my device without any problem. Did you try contact Goodwe support?

Stortkoker · September 23, 2022, 6:53pm

Hi michal,
Nice work! do you have the nice svg icon available for use?

Michal_Stranik · September 23, 2022, 8:23pm

Hi @Stortkoker , I don´t understand your question.Could you be so kind and clarify it for me?

Stortkoker · September 24, 2022, 10:54am

You used some nice icons on your virtual devices, I hope you could share these.

Super! Many thanks

Lintin · October 10, 2022, 6:46am

Hi @Michal_Stranik , have you looked into to send commands via this app to GoodWe? I have the battery solution and would love to be able to choose from triggers (electric prize) when the battery should start chargning/dischargning.
Thanks,
