Domoticz

Posted: **Saturday 17 March 2018 12:02**

Dear Alla..
Did run this script for a few years...
I need to do a clean install.
And now i cannot get the script to work..
When i read the topic i need a specail version of python..:

Code: Select all

odroid@odroid:~$  sudo apt-get install idle-python3.4
Reading package lists... Done
Building dependency tree
Reading state information... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 idle-python3.4 : Depends: python3.4 but it is not going to be installed
                  Depends: python3.4-tk
E: Unable to correct problems, you have held broken packages.

Only i still get an error..
hope some will help me

Thanks

Still working like a charm! thnx.

anyone idea how fast i can run crontab to read out Ginlong? Because 5 minutes interval is to slow, thinking about 10 seconds or so..

Don't know if ginlong will run at that frequency..?

Where do i have to start?

Installed Domoticz on raspberry.

Version 4.97 and python is 3.5.3

First make the virtual device and what sensor type do i need to choose?

And which version of the scripts can i use?

Thanks for helping Tim

Using the wiki would be a nice start to get some ideas on how to create the virtual sensors.
https://www.domoticz.com/wiki/Omnik_Solar_Inverter
The rest comes down to writing down the idx values and using the script in cron.
Version of script depends on the inverter type you have. Probably the last script in the forum is usually the best one. I always start reading at the end and move my wake back to front of the thread.

Step1
Got the Ginlong-script running with a SOLIS DLS_L aka DLS_E hooked to a SOLIS700.

Step2
My other inverters by means of their loggers upload info to PVOutput.

Obviously (for complete picture at one place) than a desire to include/upload the SOLIS-information in this collection at PVOutput.
Info on Power and Energy is available from the script 'helping' Domoticz,
Have produced & tested an annex to the Ginlong-script doing that extra job.

Step3
For compatibility of graphs at PVOutput now looking for a source of SOLIS' info on Input_Voltage and Inverter_Temperature.
In the Ginlong monitoring pictures this info is present.
However, calling the infoURL does not show this information.
Therefore the question is: which other URL should be called to get access to that info?
Somebody having that information?

Are any other 'interesting' URLs available to get info from the SOLIS inverters (documented + undocumented)?
Either on the LAN, or at the Ginlong-website?
Example for my FP4All-Loggers: http-URLs, json-URLs and xml-URLs.

As announced under Step2 of my previous message, have extended the script which reads & feeds for Domoticz with a 2nd section feeding to PVOutput.

The code of the full package is below.
Changes relative to the original script:
- text-bar at the start of the 1st, original identifying the script and it's status
- line numbers added in the 1st section to help in trouble-shooting
- 'closing' bar for the 1st section after line 75
- 2nd section prepares and performs the upload to PVOutput
- I could have used the same parameter-names all over the script, but

I'm lazy, and therefore a transition section performs translation between the variables from the 1st section towards the application in the 2nd section
- The 1st section performing upload to Domoticz applies etotal: it works => OK
However, the resolution of etotal is 1 kWh and the resolution of etoday is 0.1 kWh: therefore etoday seems the better choice for the upload to PVOutput.
In the transition section therefore a formula to multiply etoday by 1000, because PVOutput requires all energy-uploads to be in Wh.
- pay attention to proper setting of the cum-flag (due to above argument now set for upload of etoday)!
- Printlines in the 2nd section are aid for checking the upload.
- On purpose no linenumbers added to the 2nd section, because to be foreseen that some people will modify & squeeze the script by taking out the redundancies and by application of the same variable-names all over the script.

Kudo's to the devros and his wireshark skills.

Pay special attention to the following values:
pn= on your wifi stick or can be found on the shinemonitor portal after signing in the regular way
sn= the serial number of your inverter. Can also be found on the official portal
devcode= this tricky number you have to extract using for example chrome f12 (under network) to see an initial string between your browser and shinemonitor. It seems every brand has its own devcode.

Just run with Python3 as cronjob every 5 minutes or so.

Have fun!!.

@devros, where can I find the companykey ?

Posted: **Tuesday 18 September 2018 10:08**

@devros & sincze

How applicable is your latter script for the Ginlong-inverters?
[In my configuration a cabled monitor-plug is the interface between the Ginlong SOLIS700-inverter and the LAN.
imho that is equivalent to a wifi-monitorplug]

Any further hints where to look and for what?

Posted: **Thursday 18 October 2018 18:53**

Totally new to both domoticz and most things to do with home automation so please bear with me.

I have a solis inverter that sends via a wifi dongle to ginlongmonitoring.com. At the monist I'm failing at the first hurdle of running stationed.py successfully!

I've saved the script from page 1 of this thread to my pi inserting my username and password that i normally use to log on to the website to view the inverter data online and then run the script and get this.

Code: Select all

Traceback (most recent call last):
  File "stationid.py", line 29, in <module>
    token = root.find('token').text
AttributeError: 'NoneType' object has no attribute 'text'

Normally I log in to https://www.ginlongmonitoring.com and noted the script uses http:// but changing this gives the error below. Any suggestions to retrieve the station id please?

@StKilda

Sometimes small things make the difference:
what did you use for Username?
Must be the email-address with which you login to the website, NOT a choosen username!
And don't forget the '' around the inserted info!

Have adapted the py-script a bit to make that clear, incl. addition of line-numbers as aid for erro-trapping.

thanks - although fairly sure I got that right. as I am using my email address and password within the quotes. I have noted that when logged into ginseng the url of the website is

https://www.ginlongmonitoring.com/Termi ... ?pid=12345

I am guessing 12345 (not the real numbers) is the station id?

ok so there is the text: As far as I can see it is as per your instruction: note my email address:

Compared with my script-version you miss 1 line with definition of station-id.
Without that line 14 the script obviously misses data.

@arnaudarduino

If username, password and stationid are correct, then the script should run.
On the other hand, for myself took quite some time before I solved the puzzle which info to insert how&where [for Ginlong]:

the documentation is far from clear .............

Posted: **Tuesday 29 January 2019 17:16**

Hello all - found this topic while trying to pull data for my Solis (Ginlong) inverter.
It looks like there is a new ginlong monitoring website http://m.ginlong.com which is much nicer than the old www.ginlongmonitoring.com The new website provides JSON feeds of data, which is great for scraping and pushing to Domoticz / influx. There's also a mobile app called "Ginlong Home" which is quite nice too.

I had to re-register for the new website - there is an option to bring user accounts across, but it didnt work for me. Once I'd re-registered I had to add the serial number for my wifi stick (I did this through the mobile app, but may be possible through the website). About half an hour after i'd done that data from the old website had transferred over to the new website.

I'm not particularly familiar with python, so havent attempted to modify the code in this thread, but I have posted an example node-red flow that pulls the data:

https://flows.nodered.org/flow/1a1e2bac ... 930fe788f0

Effectively, the flow submits a POST to

Code: Select all

http://m.ginlong.com/cpro/login/validateLogin.json

including a few fields such as "userName"="yourusername", "password"="yourpassword", "lan"=2, "domain"="m.ginglong.com", "userType"="C"

This logs us in, and provides a session cookie which we need to pass on further calls

Next, POST to

Code: Select all

http://m.ginlong.com/cpro/epc/plantview/view/doPlantList.json

to retrieve a list of Plants -

Then, from the returned PlantData we use the plantID in the querystring to GET

Code: Select all

http://m.ginlong.com/cpro/epc/plantDevice/inverterListAjax.json?orderBy=updateDate&orderType=2&pageIndex=1&plantId=***PLANTID***&sequenceNum=9&showAddFlg=1

which returns a list of inverters - and from that we can POST to

Code: Select all

http://m.ginlong.com/cpro/device/inverter/goDetailAjax.json

including a form field of "deviceId" = ***our inverter ID***

Which will bring back a large set of data. I haven't explored this in detail, but there are readings for each input string, providing volts, amps and power - along with current output power, daily output power, monthly etc.

Hope this is helpful or useful to someone.
Thanks,
Andy

Sure a new entry to Ginlong ready for exploration!

Unfortunately myself not (yet) able to shift from portal1.0 to portal2.0
When trying the ' account-shift-function' at the new URL,then get the report

Sorry,system is too busy to get your account information
on the platform 2.0 in time,
please click "retry" to try again
or call our customer service directly
Platform 2.0 account information not obtained

Trying an alternative rout to Login or to Register (for a new account), the response for the Username is either 'Invalid Account' or ' Wrong username / password', dependent on the info inserted.
Also see stories that proper & fast response on the new portal is dependent on the applied browser.
Apparently the Portal2.0-software is far from foolproof ........

;-( No Ginlong Helpdesk, and the telephonenumber in China is not a real help:
not really Customer Support.
