openhabian comes with all, if the installation is finished, OPENHAB should be running as a service.

the installer checks the architecture the installer is running on. Depending on the detected plattform default java package is being installed

build-image/openhabian.conf:# Java architecture mode
build-image/openhabian.conf:java_opt=Zulu8-64
build-image/openhabian.pi-raspios32.conf:# Java architecture mode
build-image/openhabian.pi-raspios32.conf:java_opt=Zulu8-32
build-image/openhabian.pi-raspios64beta.conf:# Java architecture mode
build-image/openhabian.pi-raspios64beta.conf:java_opt=Zulu11-64

In openhab-config menu 40 => 45 it’s possible to select from a list of java packages.

You would like to write a config file to a share on the Raspi from the computer you run visual studio on ?
Is the share successfully mounted on the computer you run visual studio on ?

My intention is to edit the config files in my host Raspi 192.168.0.15.

I think my share is successfully set up. Used explorer, open access, entered 192.168.0.15, and I see the 192.168.0.15 under Network.

Also visual studio shows settings.jason: {
“openhab.host”: “192.168.0.15”
}
Is this correct?

I also created a drive in explorer where the 192.168.0.15 files are located by using “easy access”.

Went back to Vis Stu on explorer>start.add workspace folder; and got this error repeated twice:
[Error - 9:39:48 AM] Connection to server is erroring. Shutting down server.

Suggestions?
Thanks

Thanks
How do I know if openhab on raspi is running as a service?

6

Enter 192.168.0.15:8080/start/index in a browser and you should see the dashboard.

7

Yes I got the dashboard.

8

So OPENHAB is running and will be restarted after a reboot because the openhabian script installed it as a service.

9

Am I still in trouble since I have an error explained in reply 4.

Also now I am missing my config files in Vis.

Any suggestions?
Jim

Not sure how to restart. Not sure what I am looking at the docs.

Should I cycle power or is there another soft start method?

Thanks

To reboot: login to your Raspi and run

sudo reboot

then all services will gracefully be shutdown and restarted once the host starts again.

Gentlemen

It appears i can access demo configurations. I tried to bring up the Preview Map by selecting the openHab icon in the upper right-hand corner, but it brings up a blank screen when on all demo items.

server output error: [Error - 11:41:45 AM] Connection to server is erroring. Shutting down server

I have no clue what UI you are looking. Please state the link you are using.

What are you referring to by “Previw Map”?
