SolarEdge via LAN interface

[McMelloW]

Very interesting indeed. Will try to install as well and perhaps optimize the script in order to sent the sensor info to Domoticz.

Thanks!

Looking forward to that.

Hi everyone.
I can communicate with my solaredge SE3000H with command on windows console.
I have created 11 dummy devices with idx' numbers, correct ip and port of domoticz sever.
I have this dzVent script that doesn't update dummy devices :

return {
on = {
timer = {'every minute'}
},
execute = function(domoticz,device)
domoticz.utils.osExecute('perl C:\\Mia\\solar2.pl -n -m 0 192.168.1.13 > C:\\Mia\\SEoutput.txt')
domoticz.log()
end
}

All seems to work and no errors appears in logging domotics.
Domotics create the file SEoutput.txt with correct content:

1581066840,4,1822,1850,129345,245.40,7.44,390.50,4.74,32.55,0,0

bat devices don't receive any updating and report all 0 value.
Thanks everybody who will help me.

I have to add that if I add a the command
Print 'Hallo' at the beginning of script perl solar2.pl, at the beginning of file SEoutput.txt Domoticz write correctly Hallo and values of my solaredge.
I think my script Solar2.pl have something wrong bat I don't know what.
I attach my file that I have modified in txt file.
Thanks

Hi

You are missing the -z parameter

domoticz.utils.osExecute('perl C:\\Mia\\solar2.pl -n -m 0 192.168.1.13 > C:\\Mia\\SEoutput.txt')
domoticz.log()

should be

domoticz.utils.osExecute('perl C:\\Mia\\solar2.pl -n -z -m 0 192.168.1.13 > C:\\Mia\\SEoutput.txt')
domoticz.log()

I found sunspec_ardexa

It ia a python script and is working much faster then the pearl script

https://pypi.org/project/sunspec-ardexa

Anybody worked on this already ?

I have found that

sunspec_ardexa log 192.168.1.140 1 /home/pi/sun

Generates a nice .csv file in the logdir. But where or in what file is this generated as I would like to make the json calls from
there directly into the Domoticz

Anybody ?

Contacted the support email address.

Till now very responsive , hopefully I get some hints so can modify the script for Domoyicz

Thanks frejjn. Now is all OK.

Guys,

Who already installed the sunspec_ardexa python tool ?

Can you please run the below command and tell me in which directory your sunspec_ardexa.py is located ?
I like to see the full path.
If you do not understand the question.. please run the below command and sent the output

Code: Select all

sudo find / -name sunspec_ardexa.py

I have found where I can / have to change the file in order to use sunspec_ardexa as an interface between the SolarEdge and Domoticz.
I will have a test version ready this week, but need some help from you guys for testing on serveral systems and feedback on the install.

Will keep you updated...

Frank,

Code: Select all

pi@mcmellow-pi:~ $ sudo find / -name sunspec_ardexa.py
/usr/local/lib/python2.7/dist-packages/sunspec_ardexa.py

I am not sure or i use it. But it is on my RPi present anyway.

[freijn]

Perfect, McMellow

Same place as me

If I have made my modifications to the file, I think you would like to use it

To make the script work you have to install several PERL modules:

@Jackb Many thanks!
I do have it working with update every minute when there is no light and "every second" when my Aeotec ZW074 MultiSensor Gen5+ gives Lux > 0 but energy Today in device SolarEdge Actual Power DC and AC is lower than https://monitoringpublic.solaredge.com/ ... /dashboard
Any suggestions?

i.e. Updates are done between 00:01 and 23:00

I fire the script to update the solar when the P1 update comes in.

I do fire it from the update event of the P1.
Within this P1 update event you could check the Lux...

I've no P1?

Ohhh sorry... Still I would solve it in Lua of Dzvents.. not in bash...

Guys,

I have started a new topic for the Python SolarEdge script

My issue is that the dummy devices (Instant+Counter, Computed) gets correctly? updated with Power but the calculated? Energy is a bit to low.
Today I do have DC Energy = 6.084 kWh and AC = 5.994 kWh
https://monitoringpublic.solaredge.com/ ... /dashboard has 6.185 kWh

[freijn]

I do not have computed but from device :

Perfect match.. although SolarEdge does a round up...

OK, I'll change AC Power to From device and see, fingers crossed
You can get three decimals on the SolarEdge page if you change to month view and hover with the mouse over the days
