LG ESS PV System

Buktahula · April 12, 2023, 4:05pm

I created an addon based on the pyess python script for LG ESS PV Systems.

How can I test this integration? From the sources it looks like it’s not completed?

Ephigenia · April 28, 2023, 10:55am

I got into contact with Buktahula who updated the GitHub project also with example template and sensor configuration and with that the add-on works like charm. Here’s a screenshot of my dashboard created using the ESS values:

How do I install this addon?
When adding it as respository, HA tells me my processor or OS is not compatible…

Hey there,
what exactly did you do with the sensor configuration to get it working?
My MQTT broker shows the receiving ESS-data in the logs, but I don’t have any entity shown up in HA.

Got it. My testing Pi had an old 32bit OS running🤦🏼‍♂️

@n3096 You have to add the code from the sensor.yaml to your configuration.yaml or better in your personal sensor.yaml (!include).

Hi,

i Have installed the LG ESS PV Addon on my HA.
Did you install the MQTT Broker?
And how does the Entiteten comes into HA?

Hast du diese manuell angelegt in der pv.yaml oder kamen diese automatisch?
Bei mir hängt es aktuell da, das ich keine Entitäten habe.

Danke!

Hi @morph,

I got a LG ESS too and installed the LG-AddOn and the Mosquitto-Broker AddOn.
Then configured the MQTT-integration and finally added the sensors to sensors.yaml - or you might put them into configuration.yaml.

I took the example-yaml-file from github, there is all I need for now.

Läuft für mich soweit

Thank you very much.

My Failure was that i thought that the ess Password is the one to go into the System of the LG as an installateur.
No, it is an Password what you need to extract anyway…

For now it works. Only the Battery for the charging dont work yet. Maybe tomorrow when its sunny

sorry that I didn’t report the problems and couldn’t help, unfortunately I was very busy at work and privately. But I see that you were all able to help each other, if anyone has any suggestions for improvements to the instructions or something, just contact GitHub.

Hi everyone

can someone explain how to install the addon anche get the ess password? I tried to run the command but nothing happen.
Thanks

pb1971 · April 6, 2024, 8:15am

Hi,

it works very well after i modify all sensors in the example sensor.yaml from

ess_…

to

ess_ess_…

The only Thing i miss is pv3.

Thanks for this.

Hello,

now got all that going and I really like your dash-board card. You’d like to share the code of that?

By the way, by searching around for the ESS device password, it’s mostly the MAC adress of the ESS in lower case w/o the : so you can easily find out by having a look into your routers UI

Continuing the discussion from LG ESS PV System:

Sorry, i dunno wether it is the right thing to ask here, because a lot of time has passed since your last posts,
Well i tried everything to get it to work but i cant see my mistake: i did the configuration as followed:
password: “macAdress” extracted by pyess and double checked with router arp table
mqtt-server: i entered the ip Adress from home assistant
mqtt-user: my user
mqtt-user-pw: as entered in mqtt configuration but contains special characters like !?$

i use for mqtt the port 1883 - but cant define it

added sensor.yaml
with sensor: !include sensor.yaml

log looks like this:

21:31:54] INFO: Initialize the essmqtt configuration…
INFO:pyess.aio_ess:fetching auth key
WARNING:pyess.essmqtt:Expected exception while talking go ESS or MQTT server, restarting in 60 seconds.Usually this means the server is slow to respond or unreachable.
