GoodWe Solar: get data from the new semsportal (lua script)

[sandeman684]

I'm trying to get this working however i cannot get the curl command to work. I run windows 10 on my desktop and domoticz on a raspberry pi. Where do i put in the curl command? In de CMD on win 10 or in on the Raspberry Pi??

I think in Windows 10 you can run curl (https://stackoverflow.com/questions/950 ... on-windows) but it is probably better to do it on the RPi as domoticz will also use it from there. You should get the same response on both.

you have create your own sensor.
for hardware you have to create a virtual sensor from the type "Dummy (Does nothing, use for virtual switches only)".

then click on "Create Virtual Sensors", name the sensor "solar panels" and choose "sensor type" - "Electric (instant + counter)"

Do you have to create a new sensor or is it possible to use your existing "Goodwe solar inverter via Web API" idx-code?

you have to create your own sensor.

I have implemented this script without to much problems. The only thing i see after a couple of days is that the total value of monday is al wrong. It's not 19.2 kWh, but more around 8.8 kWh if i check it in the semsportal.

All of the other days are correct, i dont get it. Does anybody have an idea?

[Kencirot]

I experience the same issue as Marktap. The daily total of previous day is being used untill the currect day is higher for me.

I also notice when there is no power output I still get the last remain known output showing up (e.g 36Watts from 22:00h onwards till the morning).
Is there a way to set it to "0" when the solar system is offline?

Hi
I have installed the script and it works great.

There is one error remaining:
2019-06-08 07:28:10.493 Error: EventSystem: Warning!, lua script Solar Panels has been running for more than 10 seconds

i also try the upload to pvoutput script, but that needs some more work and my scripting is not that good.

lua script works like a charm. Up and running in no time. Thank you so much.
As by default I always build the stuff in Pass2PHP (and have some sort of multi-threading).
I updated my Github.

? so you make a php file from the Lua script?

[sincze]

? so you make a php file from the Lua script?

Yes, basically I rewrote the whole thing in PHP. As all my scripts use PHP. (Pass2PHP user)

This for me has the following advantages:
- I can run it outside of Domoticz and not be scared of 'script has been running for more than 10 seconds ' clogging up my 850 devices and 10 (different branded) inverters.
- In addition I could build some additional failure checks. If the webserver is not available.
- It integrates in Pass2PHP
- It can be used for non Pass2PHP users.

However for the typical user I would go for the lua.
- It works fine.
- Easy to implement

I even have it running on my spare pi.

impressive, ia'm truck with copy and paste only.

Also same problem.. Think of editing the database to correct..

This seems to be an issue with all my different branded inverters indeed within domoticz.
Seems like a Domoticz representation graph issue to me as the json request is processed correctly and device is updated correctly as well. I am running Domoticz V4.10730.

I also notice when there is no power output I still get the last remain known output showing up (e.g 36Watts from 22:00h onwards till the morning).

That I corrected with a statement (not within lua) to check if the current time is after sunset. If so I update the device with

Code: Select all

0;<daily_generation>.

ik got this problem 2 how to solve it?? i can't gat the solution

if have made som changed so i have a 0 value when de inverter is nog genarating

i get de status of the inverter

Status = getValue(splitString, "status")

if that is
1 = Generating,
0 = Waiting</option>
2 = Fault
-1 = Offline

if Status == "1" then
status_text = "Generating"
elseif Status == "0" then
status_text = "Waiting"
elseif Status == "2" then
status_text = "Fault"
else
status_text = "Offline"
end


so i can create a 0 when the status is 0,2 of -1

if Status == "1" then
UpdateDevice(sensorSolarPanels, current..";"..zonTotal)
else
current = "0"
print("current :" .. current)
UpdateDevice(sensorSolarPanels, current..";"..zonTotal)
end

and i use eTotal = getValue(splitString, "eTotal")

so i can get the total of my production

Thank you for your response. I’m not that experienced with Domoticz, can you tell in detail how to:

That I corrected with a statement (not within lua) to check if the current time is after sunset. If so I update the device with

Code: Select all

0;<daily_generation>.

Thank you!

Thank you!

I can help you if you are willing to consider moving to a Pass2PHP script kind of a solution.

I still have a problem retrieving the data.
Does anybody have an idea how to solved this error?

Have you been able to fix this error?

Anybody who has this script working on a Synolgy NAS, as I'm unable to find much about syntax differences between Pi and Synology if there are any.
First error already occurs at the first line of executable code: local Username = ... Unexpected keyword local near Username

Yes it is working on a DS412 as an alternative I created
However you could also look at: https://github.com/sincze/Domoticz/blob ... Goodwe.php
