Goodwe

[Danny]

Dear readers,

I am looking for the api of Goodwe inverters (Semsportal)
on Github I found the below but I don't know how to integrate this into the W4K.

Can someone help me with this?

thanks in advance

Code:

Post what you get in Logs tab.

Thanks admin
how do i get the power logs from the inverter?

Admin this works perfectly thanks
I will continue with this.

I will continue with this.

@Danny: What is your experience with the script? Is it working? Have you made further modifications?

Many thanks!

How can I pick a variable out of the table? 

For example I want to pick out “pac” and write this value to a group address. How would this work?

Many thanks!

Best Regards 
Steffen

[admin]

Use this:

Code:

1

grp.checkupdate('1/1/1', invert_full.pac)

[pioneersteffen]

Use this:

Code:

1

grp.checkupdate('1/1/1', invert_full.pac)

Many thanks admin! Works perfectly! :-)

I have a system with 2 inverters and one batterij, connected to one inverter.

I have copied the code above, but I have the impression that only the data from one inverter is displayed. How can I display the data of the other inverter?

[admin]

Try this for multiple inverters. The order of the returned data might not be constant. So you might have to check the serial number (sn field) invert_full_1 and invert_full_2 tables to distinguish to which inverter the data belongs to.

Code:

12345

invert_full_1 = response.data.inverter[1].invert_full log(invert_full_1) invert_full_2 = response.data.inverter[2].invert_full log(invert_full_2)

I works perfect! Thank you very much.

But, now, I have the error: attempt to concatenate field 'api' (a nil value) stack traceback. The line with causes the error is: 

Code:

1

url = response.api .. "/v2/PowerStation/GetMonitorDetailByPowerstationId"

A couple of days ago, I didn't have this error. I tried several thing, but I can't find what is causing the error. Can you help?

The response looks fine. You can modify this part to log only when api field is missing from the response, then check what the log says:

Code:

123456789101112131415161718192021222324252627

if res and code == 200 then   response = json.decode(table.concat(response))   headers.token = json.encode(response.data)   if not response.api then     log('invalid response', response)   else     url = response.api .. "/v2/PowerStation/GetMonitorDetailByPowerstationId"     response = {}     body = json.encode({ powerStationId = powerstation_id })     headers["Content-Length"] = #body     res, code, hdrs, stat = socket.http.request({       url = url,       method = "POST",       headers = headers,       source = ltn12.source.string(body),       sink = ltn12.sink.table(response),     })     response = json.decode(table.concat(response))     -- ...   end end

Thank you very much for your help. 

I still have one question. In the Goodwe app, I can see how many we inject. I want to load in into the LM, so I can ask to the heat pump to make more hot water so it fulfills also the function of a battery. When I send use the following script:

Code:

1234

url = response.api .. "/v2/PowerStation/GetMonitorDetailByPowerstationId" response = json.decode(table.concat(response)) log (response)  

The log ends with ..., so I have the impression that not everything is saved in the log and that I can't see everything.

Is there a possibility to saved everything, so that I can see alle the information that the LM is getting back.

For testing purposes you can write the results into a file before decoding it:

Code:

12345

response = table.concat(response) io.writefile('/www/log.json', response) response = json.decode(response) -- log(response)

Then open the log in your browser: http://LM_IP/log.json
You can use https://codebeautify.org/jsonviewer to view the JSON contents in a more readable form.
