Cannot connect to ESS

[gluap]

As the message says: get_password is only known to work on the ess wifi (the one opened by the ess), not your home network. In that network, the ess ip should be valid.

Thanks for your response - understood. However, how do I create a direct connection to ESS. I have only been able to connect from a smartphone via EnerVU app. How to do this under raspian OS or ubuntu OS 18.4, where an EnerVU app is not available?
My ESS is configured via WLAN , no LAN cable.

You need to enable the ess wifi like shown on the 2 screenshots of the lg enervu app below and then connect to the wifi from a computer that you can run the "esscli --action get_password" command on (Of course you need to change the IP address back from 192.168.178.45 to the default 192.168.23.1). Once you have the password you can then connect to your own wifi again and use pyess from there.
PS: Thank you gluap for making this!

Thanks for the procecure, with which I could connect and get the ESS password.

Next, I connected via WLAN to my 7490 router and tried to receive data with esscli:
esscli --action get_data --password
The command failed.

The Wifi is the local WLAN , not the ESS WLAN which is disabled now, the 192.168.23.1 is no longer available.
The ESS Ip-address 192.168.178.45 in my own wifi can be ping'ed.

Traceback (most recent call last):

raise ESSException("could not find any ESS devices via mdns")
pyess.ess.ESSException: could not find any ESS devices via mdns

Also the list_ess (which initially worked) now brings this message:
File "/home/stephan/.local/lib/python3.9/site-packages/pyess/ess.py", line 266, in find_all_esses
raise ESSException("could not find any ESS devices via mdns")
pyess.ess.ESSException: could not find any ESS devices via mdns

Can you please give advice how to proceeed from here?

I finallly found a problem within ESS communication setup which is now solved.
The get_data command now smootly delivers data.

Thank you very much for assistance.
The pyess interface is a great solution!

Tzhe issue can be closed.
