I am planning to install and run the openremote controller and other components on a Stratus plug computer which is an ARM CPU based computer running debian linux. Has anybody done this already? Looking for help in this regard. Please help.

If it's running Debian, you should be able to just "apt-get" the Java VM onto it, and away you go - although you may need to acquire some other libraries if the default distribution wasn't built statically - but on mine I just grabbed the Java VM, downloaded the OR zip, and ran the " start" script and off it went - although I did have to alter a few things to get the webserver running as I run other web servers on the ports that OR defaults to

The main questions is how much RAM does the plug have?

I have a NAS (also running Debian) with 6GB of RAM, and the Java process running OR eats 3%-5% of the memory - which is about 300MB of RAM.

If it doesn't have lots of RAM, it may swap a lot, and if it's a plug device, I imagine it would be using an SD Card as it's filesystem, and depending on how swappy the Debian install was set to be, it may wear your SD card a bit?

Thank you very much Mr. Truman. I just saw your reply now. The Plug has only 512MB RAM. If it does not run anything else except Open Remote and its accessory components like Java VM, do you think it will still swap a lot? Thanks again for the prompt reply. I shall now download the OR zip, install it and see how it goes.

512MB should be enough.

Not a problem - did it work?

You can google "Linux swappiness" and amend how much swapping the thing can do, but that may affect performance depending on RAM utilization - but given Juha says 512MB should be enough, you should be ok

(just don't go installing too many other things on it)

Thanks everybody and sorry for the late response. I have installed "Oracle Embedded Java SE 6" and OpenRemote controller without any hiccups. OpenRemote is able to start up. I need to configure it and continuosly run it. Shall do so and give feedback.
Thanks again.

I have come back with more clarifications. Please help me.

Now, I am able to start up the open remote controller on the plug. It starts running but displays a few INFO messages in the middle of its startup for which I need help to sort out what it says. I am giving below the console commands and output messages:
root@debian:~# export JAVA_HOME=/root/java/ejre
root@debian:~# cd Open*
root@debian:~/OpenRemoteController# pwd
root@debian:~/OpenRemoteController# cd OR

With this message, the controller seems to run on.

My plug computer has an ethernet interface. This I connect direct to my laptop's ethernet. I can see the addresses are for the laptop and for the plug computer. I can ping each other successfully. So the connection is very much ON.

Now when I attempt to do from my browser on the laptop, it fails. But again if I do just on the browser it connects successfully and shows the "It works" message.

What is the mistake that I have made in installation that resulted in this behavior and how to correct it. Please help me.

Sorry folks. I could get the controller home page on the browser with 8080 port. So please only clarify on the startup INFO messages that seem to indicate that something is wrong.

Posted by m.gopikrishnan at Feb 22, 2014 12:33

Further to my last post, in spite of the INFO type of messages coming at startup time, looks like the openremote server is running on the plug. Now I can connect to the controller from a laptop using the browser, and sync with the designer component after supplying username and password. Also I could access the controller from an android app and got a sample panel to display on it.

Thanks for the handholding so far. Now I have to go ahead and figure out how to connect to some z-wave sensors and switches and design some control apps. Can u please point me to some information on getting started with these?

Try the search function at the bottom of the forum page with the obvious terms:
