Omnik Export Script

[pgit]

It looks like Woutrrr has further devellopped Omnik-Data-Logger on https://github.com/Woutrrr/Omnik-Data-Logger.
It now uses a new file PluginLoader.py for output to Mysql, PVoutput, CSV and to the console.
Also make note of the additional settings in config.cfg.
Since the procedure to enable or disable these output options and to log does not use xxxx_enabled variables anymore, the modifications to the script in order to output to Domoticz should be adjusted as well.
Sorry, I am not a Python programmer...

http://tweaken.blogspot.nl/2015/01/domo ... utorg.html and http://www.domoticz.com/wiki/Upload_ene ... o_PVoutput both show (pretty complicated) ways to combine data from a (smart)electricity-meter (import and export) and PV energy data (production) to calculate consumption and upload this to PVoutput and Domoticz too.
I dislike to schedule more than one script to make api-calls and upload to PVoutput, with the risk of overlapping etc.
Couldn't someone combine calculating consumption and uploading this to PVoutput and Domoticz in the adapted OmnikExport.py script to make things simpler and less prone to errors?

Thanks to these post I'm almost ready at a point it works.

I still have two issue:
msg.e_today() and msg.temperature() both complain:
'svalue':msg.temperature(),
TypeError: 'float' object is not callable

python LiveStats.py shows:
ID: 000xxxxxxxx
E Today: 2.1 Total: 47.0
H Total: 0 Temp: 31.4
PV1 V: 176.0 I: 0.2
PV2 V: 0.0 I: 0.0
PV3 V: 0.0 I: 0.0
L1 P: 23 V: 230.5 I: 0.1 F: 50.0
L2 P: 0 V: 0.0 I: 0.0 F: 0.0
L3 P: 230 V: 0.0 I: 0.0 F: 0.13

My best guess is that the numbers don't correspond to the give position number in the functions in InverterMsg.py.

Can someone help me out here???

Thanks

Hi,

New update:

I removed :
@property
above def temperature(self) & def e_today(self)

in InverterMsg.py

Now it seems to work without errors ... Stll don't understand it completely.. anyway its dark so not way to test it anymore.. Hope this is helpful for others too.

Hello, (sorry for my poor english...)

i hope someone can help me..... i'm trying to get this work for a couple of weeks now but without any succes..
Livestats.py and omnikexport.py is working and I managed to get the pvoutput working as well.. (but unfortunately no automatic update....)

Im trying to visualize the data in domoticz, i've put the text in Omnik-Export.py.
But i'm getting the following error:

pi@raspberrypi ~/domoticz/Omnik-Data-Logger $ python Omnik-Export.py
Traceback (most recent call last):
File "Omnik-Export.py", line 82, in <module>
s.sendall(InverterMsg.generate_string(wifi_serial))
AttributeError: 'module' object has no attribute 'generate_string'

What do I have to change to get the string wright? I've tried the copies that were uploaded in the post above but i can't get it working...

Hope someone can help me with this...

Hi,

The following is missing in InverterMsg.py

def generate_string(ser):
'''
The request string is build from several parts. The first part is a
fixed 4 char string; the second part is the reversed hex notation of
the s/n twice; then again a fixed string of two chars; a checksum of
the double s/n with an offset; and finally a fixed ending char.
'''
responseString = '\x68\x02\x40\x30';

doublehex = hex(ser)[2:]*2
hexlist = [ doublehex[i:i+2].decode('hex') for i in
reversed(range(0, len(doublehex), 2))]

cs_count = 115 + sum([ ord(c) for c in hexlist])
cs = hex(cs_count)[-2:].decode('hex')
responseString += ''.join(hexlist) + '\x01\x00'+cs+'\x16'
return responseString

Paste at the end of the file and it should work.

Thanks for the response,

I have adjusted the text ... but unfortunately it does not work. I get the following error code:

pi@raspberrypi ~/domoticz/Omnik-Data-Logger $ python LiveStats.py
Traceback (most recent call last):
File "LiveStats.py", line 7, in <module>
import OmnikExport
File "/home/pi/domoticz/Omnik-Data-Logger/OmnikExport.py", line 146
"""
^
IndentationError: expected an indented block

Does this has to do with the way I have saved the files?


Sincerely

[jpbtew]

wrong copy/paste.....

pi@raspberrypi ~/domoticz/Omnik-Data-Logger $ python LiveStats.py

Hi,

The error is related to indenting, see text file.

Thanks for your reply,

i'm think i'm not that smart...
I do not know what I can do to resolve this......

[jpbtew]

pffffff.. getting grey hair......

pi@raspberrypi ~/domoticz/Omnik-Data-Logger $ python Omnik-Export.py

After each problem there's another problem...


nobody a working folder for a Omnik Data Logger???????

[jbr79]

Try these files:

You need a working git clone and subsequently a config file that has no space characters before the # signs (the comments) or else all will fail...

Good luck

Thanks for your help!

unfortunately I do not get it working. I have checked all the spaces in the config file and that's ok.
Livestats.py also works well and also the upload to pvoutput.

I've attached my files..
I'm using Omnikexport for the PVoutput upload. (this is working great)
I'm using Omnik-Export for Domoticz.. (Not working...)

There's nothing to do but check everything again.... and again.... and again..

[jpbtew]

YEAH! started over again and copied al the things that i was sure of.
A day of trial and error but now it works!

Thanks for your help, it helped me a lot!!!!

Hopefully its the correct topic
but when running python OmnikExport.py
I am getting below error message

[sincze]

Maybe I am missing something.
I see: File "/home/pi/domoticz/Omnik-Data-Logger/outputs/DomoticzOutput.py", line 13, in <module>

and

#change to correct folder.
config.read(['/home/pi/Omnik-Data-Logger/config-default.cfg', '/home/pi/Omnik-Data-Logger/config.cfg'])

Could it be it is not finding the config file ??

Hello,

Still working on it and i got it to work.
Thanks for the help.

I really like this idea about the Omnik plugin for Domoticz. I've not tried it yet, still reading on how and what to do to get my solar panel data into Domoticz. Would this plug-in with my Omnik device beause it has serial number: 626267xxx?

Don't know the plugin deals with the local Inverter webserver.
This one does not care about the serial number it scrapes the data from the webpage of the inverter.
