SolarEdge individual optimizer dzVents script

[freijn]

i did , and if i do the url manual i get the response with a lot of content

Perhaps.......

how did you create the script ? as a file directly in the directory or (as i did ) in the gui interface ?

Just in the gui. save it. switch it on and saved it again. Then it is active in generated scripts

[freijn]

What type of script ? timer I assume ?

[McMelloW]

Copy - Paste from dzRequestSolarInfo.lua at github in the event gui.
Then saved it.

Hi Richard,

Very interested in your code but somehow I can't get it to work

Below my extra debug steps.
Below that the logfile of it.

of course I double checked my login password and site-id. Just thinking, could the capta be the issue here?

Hmmm, strange.

Just copy / paste the script from github. Change the lines for email, password and siteID. Saved it and switched to active.
It works like a charm. See my output in previous posting.

[freijn]

Richard,

I had to change :

if component.data and component.data.type == "INVERTER" then

into :

if component.data and component.data.type == "INVERTER_3PHASE" then

Now its working!

Cheers,

Frank

Today, I discover a difference in values of my Daily Energy Production. See picture below.

SE-DailyProduction.png (23.69 KiB) Viewed 2547 times

Actueel Vermogen SE = directly taken from the Inverter via a LAN connection to my RPi
Inverter 1 = With the use of the lua script from the Solaredge Monitor website
String 1.1 = With the use of the lua script from the Solaredge Monitor website

Why do I have 3 different values of Vandaag, all 3 from the same inverter.

[Dols]

Hello Richard,

Is there no figure for the Total Lifetime Energy? (Totale energie) I could not find it in the test output.
https://monitoring.solaredge.com/solare ... ut/logical

imo This a counter within the Inverter? At least it is also available on the monitor homepage.
SolarEdgeHeader.png

Not in that json file. Maybe with different uri. I haven't found it yet. But even then, looks like its only for the inverter, not for the individual optimizer. Thinking about this, the original web hardware already does this.

Not having tot the total energy gives some problems with the day graphs, which needs a continuous increasing value.

In my commit of may 21, i have the first attempt to calculate the "total" energy from the cumulative day energy. It failed. Currently testing a second attempt. Will take a few days to verify if this works correctly.

Thanks for your answer.
Getting the information directly from the inverter via a LAN connection contains the total lifetime production. See my picture "Totaal Vermogen SE"

Can I redirect the the http respond to a file, so I can investigate all information received from Solaredge.

[Dols]

[..]

Looks like it can't find the data. Some items in the json are localized. What is you language setting in you solaredge monitoring web site? Can be found under account settings. My guess is that you have metric setting and language dutch. That should work.

Never mind, you found the real problem.

If you want can you send me one json result? I have just a 1 phase converter. I want to check if there is more different.

What does the solaredge website say?

I don't trust my calculation to have continuous increase energy value. It has some problems on the daily rollover. I just committed a change that disables the calculation.

This makes even more complicated. An 4th number 10.92 kWh

Hmm, total energy of the optimizers can be found with next url. But it is an HTTP POST and needs an session ID.....

https://monitoring.solaredge.com/solare ... meUnit=ALL

timeUnit can be "DAY", "WEEK", "MONTH", "YEAR", "ALL". And with ALL i get the strange reading.

In this api guide http://www.solaredge.com/files/pdfs/se_ ... ng_api.pdf They speak about "lifetime" But not all API's return with this value.
Do you use the same API guide?

Quick question.
What is the difference in the device options Computed or From Device?

[Dols]

Quick question.
What is the difference in the device options Computed or From Device?

"computed" it does not use the energy (Kwh) information provided, but instead in calculates (integrates) the power (Watt) instead. This is typically used when there is no (reliable) energy information available.

"from device" stores the energy (Kwh) as provided. It expects this to be an ever growing number to work correctly. (total energy). Providing it with the day energy will break the day graph, maybe some other stuff too.

No i don't use the official API. I use the API the monitoring website is using. Found a hint somewhere on the internet, from there it's reverse engineering.
