I am using the B-Model of an RPi which I have as well overclocked to 900 MHz, but as soon as my OR model becomes quite large (>40 commands, >20 sensors, >20 sliders and some pictures), the Pi does not start the server anymore. On my powerful Windows7 machine everything works fine and extremely fast.
Am I doing something wrong with the RPi or is this just a limitation of the RPi's processor power?

What other "mini-PC" is doing the job without stopping the OR server in case I add some graphics?
I found a similar PC to the RPi (--> but these ones are not available until late February 2014.
My goal is still using a mini-PC due to the power consumption.



Hi Marc - I had the same problem with the Pi it was just too slow and could not cope when I had lots of sensors, especially with the logs running. I went with an eBox 3310MX-AP which I tried to set up with Linux but had lots of problems - in the end I installed Windows XP and this is working fine. I also ended having to buy an external CD drive to install Windows XP and I put a SATA HD in as well. I also had trouble finding a Java version that ran on the Ebox as it is quite old architecture. For you and others just in case it is:
java version "1.6.0_22"
Java(TM) SE Runtime Environment (build 1.6.0_22-b04)
Java HotSpot(TM) Client VM (build 17.1-b03, mixed mode, sharing)

It takes about 1 minute to boot up into Openremote and I've installed VNC so I can control it remotely. It also has Auto power on so if there is a powercut it recovers fine.

Like you previously I had OR running on a fast Windows7 machine and of course the Ebox is not as quick but it is fine for OR. The ebox is definitely less power hungry though.

This post looks interesting to me.
I was thinking of buying a BeagleBone Black for running openremote for my home automation.

I would have:
30 lightpoints on z-wave
10 plugs on z-wave
11 window/door sensors on z-wave
8 danfoss thermostats on z-wave
2 Samsung TV-s
1 Plex media server

So in the end it will be a big project...
I am not so convinced now anymore this will run on my BeagleBone Black

Possibly system on Intel i3 or i5 will suit the best for you?

Odroid X2 just came to me. Installed Ubuntu 13.11.
Going to install Java nearest days.
If anybody needs can make experiments.

I havent plugged any sensors yet.
Going to use it with 1-wire devices and OpenRemote.

For so many Z-wave devices you will need the pro designer
It this case the eBox is an obvious choice. Beside the one offered in the pro bundle for 200 EUR extra you can find other suppliers too. For example

Hi Michal,

All my Z-wave devices would be linked to my Vera and then my Vera linked to OpenRemote.
So I haven't really figured out yet if I would buy the pro designer or not.

I was planning on buying a NAS for my home entertainment system.
Would running everything on the NAS be an option?

Yes, NAS is an option. But there are different NAS'es. As far as I know most experience is done with Synology.
