Python Plugin: GoodWe solar inverter via SEMS API

@jan-jaap : update runs now ! Thank you !

Awesome Work Jan-jaap!

It seems though that the data is coming trough is not what Domoticz expect it to be:

I've reset the value but am not sure if im missing 3 days of generated power. Ill investigate further.

Also:

1 of 2 MPP-trackers is going to zero occasionally but they are working both as well in domoticz. Current output value is also none.

I have the same problem in my dzVents script.

i think Goodwe now delivers sometimes nil- values, so domoticz calculaties te difference.

i think we need an otter variable witch always holds the cummelative total values.

Regarding time-out errors : the token has a live of 60 minuten, so it does not have to be renewed every time. Goodwe says renew every 50 minuts.

Fair enough .

In the fixed script no output current comes with the data. Could this be addressed?

*update:

The total generated values as of 2020 comes with the total generated daily output (even after resetting the graphs from yesterday. Could this be a bug?

Very strange; one moment it shows the correct daily value, and the next, the total quantity produced appears as a negative figure.

My dzVents script (seen here) only is capable of retrieving total and temperature, i can't find detail info on the api.
Anybody more info about the new Goodwe API?

It works now again but it has some strange results.
It seems it sometimes sends values with factor 1000 (Wh -KWh) too much.

The totals for the day are correct so not sure what is going on here. The red bar is because of the few days of errors and not counting.

@waltervl : Nice earrnings

[RNEE]

For those interested : i completed a dzVents script with fills all data i had before for 2 strings.

This is not an easy to use tool like the python plug-in from Jan-jaap. You have to set up some things manually.

It is still a work in progress but now it suits my needs.

You can find my script here : https://github.com/RneeJ/Domoticz-Goodwe-SEMSPLUS

I made a github issue for this as the plugin resets the counter due to receiving partial values from the portal. https://github.com/JanJaapKo/domoticz-G ... /issues/38

Plugin also support reading individual strings? What do you miss in the plugin that you prefer the DzVents script?

Cant wait to try it out, unfortunately the sun is letting us down lol.

Is this fix so that the total generated output will no longer comes trough on the daily value?

Is this fix also to get the PV AC output back? Cant get this one to work since..

Your plugin is great, please keep up the good work. I miss nothing in it and i will use it again if the data come in nicely.

And yes the script scans for different strings within the inverter and gets its individual data !

This dzVents script was a learning process for me. I had an life error and testing situation on hand and some time available.
I want to be able to make more scripts in dzVents but lack knowledge and experience.
I used several AI but ended up with Claude witch worked very very well.

Yes it fixes the spikes in the generated energy

I did not check all the devices. Which one is now missing? The output current?
