BMS tab is empty about bms-to-inverter HOT 18 CLOSED

netty-common-4.1.94.Final.jar is in my lib folder

Its a Pi 4B.
I'll try running directly on the pi, I need to spin up a linux build on my PC

Have you downloaded the latest Configurator application?

from bms-to-inverter.

Yes I have

from bms-to-inverter.

Please get the new Configurator app again. I've tested it and it works fine for me

from bms-to-inverter.

got latest configurator. couldn't do a clean install as the BMS tab was still empty. I copied my config.properties to the location of the new configurator and ran again. it read the configuration and I updated and did a clean install. the install window was also blank but I watched files get added and closed the window when it stopped adding files. ran ./start and the web server fails. I'm attaching the log
start.log

from bms-to-inverter.

Just tested the Configurator app on my Pi and also there it works.

The Webserver won't run if the BMS-to-Inverter application is not running. You need to select the Webserver in the Configurator and it will automatically also select the MQTT broker and client.

Have you tried to run the Configurator on a PC or laptop and then transfer the installation folder per e.g. WinSCP or Putty to the Pi?

from bms-to-inverter.

I have the gui working now. something is messed up with file permissions. if I run sudo configurator.jar all of the dialogs are blank. I tried chmod 777 and ran sh configurator. the gui is correct now but it fails to write the configuration and also fails to install. doing a combination of adding a config folder and a temp folder seemed to let me save and clean install. The web server is still crashing however. here's a new log :

b2log.log

from bms-to-inverter.

Ok, that is strange. I will have a look at that tomorrow.

The crash of the webserver is due to the Bms-to-Inverter application (and its MQTT broker) not running or not started in time.
Be sure to have the Webserver, MQTT Broker and MQTT Client enabled in the Services tab of the Configurator.
Maybe try to run the app seperately first and then the webserver.

In your installation folder run:

java -DconfigFile=config/config.properties -Dlog4j2.configurationFile=file:config/log4j2.xml -jar lib/bms-to-inverter-main-0.0.1-SNAPSHOT.jar

and then in another terminal when that is started and running:

java -jar lib/webserver-0.0.1-SNAPSHOT.jar --spring.config.location=file:config/config.properties

from bms-to-inverter.

the bms-to-inverter application fails to run:

bms_cli.log

from bms-to-inverter.

Could you please replace your log4j2.xml in your config folder with this one (please remove the suffix .txt):
log4j2.xml.txt

and run the program again to get more information. It is very strange that there is not more in the log.

from bms-to-inverter.

here you go.
newlog.log

It looks like your install did not finish downloading all the libraries. Please check your lib directory in the installation folder. I'm pretty sure its missing a file called netty-common-4.1.94.Final.jar.

But back to the problem of this issue:

1. Have you tried to run the Configurator application on a PC? How does it look there? Then you can copy the files over via SCP or a USB stick.
2. Have you tried running the_Configurator_ application directly on the PI without using VNC but a connected monitor?
3. Could you tell me what PI model you are using and which Java is installed (java -version in the terminal)

I'm sure we'll find the cause of this now pretty quickly. I've tested the Configurator application from here now on 3 Pi's (3B, 4B and 5) and its working on all 3, including PC.
My guess it might be a problem with the VNC.

from bms-to-inverter.

running directly on the Pi the configurator worked correctly without issues but I still have the crash in bms-inverter

from bms-to-inverter.

Still the java.lang.ClassNotFoundException: io.netty.util.internal.PlatformDependent exception?
Could you please delete the .m2 folder in your home folder and also delete your installation folder and do a fresh Clean install again and be sure to enable the Webserver, the MQTT Broker Server and MQTT Producer services.
Maybe the Netty Jar file is corrupt due to a incomplete download.

did a clean install on PC and copied over to the PI. it's running again but the can info is still wrong on the web page. A can dump does look correct but not the values displayed on the page

Hi,
can you confirm that the Configurator is working? Because then I would close this issue and continue the discussion in the issue #20

from bms-to-inverter.

Yes. Configurator is working correctly. We can close this
