Server Requirements

[Hannes Werner]

Hello,

is there a proposal what hardware-specs a server for OpenHab should fullfill?

Thank you very much for your answer.

[Thomas Eichstädt-Engelen]

Hi,

no, we haven't figured them out in detail! For now there are just some examples:

* Seagate Dockstar (Arm - ???)

* Pogoplug Pink V2 (Arm - Arch Linux)

* Cube (Arm - ???)

* Alix 2D13 (x86 - Debian Squeeze)

* PC (x64 - Ubuntu)

* PC (x86 - Debian)

* PC (x86 - Windows 7)

Although openHAB runs on embedded devices as well it isn't yet optimized for that. Meaning startup time is significantly longer compared to Intel-based machines. Which hardware are you going to use?

Regards,

Thomas E.-E.

hello,

thank you very much for your answer. I'm investigating into home automation and trying to find out what bus system would be best for a private house beeing build. I'm with linux for quite some time, also running a mpd music sever and an asterisk pbx on alix boards with voyage debian.

because of java I would think one would need better hardware than a seagate docstar or pcengines alix. is anyone using openhab with one of these?

cheers

yes, there are openHAB users with both :-)

Hannes,

Independently from choosing hardware for openHAB I would choose KNX as
a bus for your house if it is a greenfield, cause laying down KNX bus
requires laying down KNX cable between your sensors (switches). Unless
you have a whole house system of ducts in an existing building it is
quite complicated. On the other hand you can choose some of KNX power
line or RF solutions.
I run openHAB on D2Plug (http://www.plugcomputer.org/development-kits/d2plug/)
with oracle embedded JVM. It is really much slower in startup then on
my MacBook Pro, but after starting up it works quite ok. At least I've
never seen any performance issues.

Best regards,
Victor Belov

hello,

thank you very much for your answer. the house is currently in planning and I would like to consider KNX as bus system. my focus would be to have a fire detector in particular with a visual alarm for a deaf family member. if there are other useful scenarios for my needs please share them. one question I ask myself for example is how to trigger open or closed windows. can this be controled with wired sensors?

I would be thankfull for any hints,

cheers

[Victor Belov]

Hi,

you can do it with wired sensors connected to binary input KNX
devices, but I plan to do windows with wireless Enocean sensors and
Enocean<->KNX gateway, cause this is the only task which is visible
better done with something wireless instead of a wired bus. If you are
doing a new construction then KNX is definitely is the right choice.
I've spent about a year deciding on which way to go. I've tried Z-Wave
and Zigbee from wireless field, checked different power line
technologies and proprietary buses. KNX's most powerful point is
amount of vendors producing different types of devices which are a
priory 200% compatible with each other.

Best regards,
Victor Belov

I've just started using openHAB -> so I can't give any user experience about performance, stability and the connectivity to other systems (KNX, Asterisk, FritzBox and so).

As mentioned before, I think the really important thing about the platform is that you can install a java package. In my case I'm using a NAS from QNAP (259 Pro+) http://www.qnap.com/de/index.php?lang=de&sn=375&c=292&sc=528&t=536&n=3441 for backing up my MacBooks, DLNA, Airplay, File Storage, LDAP, iSCSI and now also for openHAB.

Of course I'm a linux guy ;-), so it was really easy to get it up and running.

What I had to do:

- install JAVA over QPKG

- download the openhab-runtime Package to my macbook

- unzip it (because of a compression problem the NAS couldn't unzip the package)

- scp the package to the NAS (scp -r openhab-runtime* nas:/mnt/HDA_ROOT/opt/openhab/ )

- modified the start.sh file (changed the Jetty HTTP and HTTPS Port)

- made the script executable

- start the server

done!

I wrote a small init Script for starting, stopping the openHAB runtime on my QNAP box.

If anyone is interested in, I can provide it here.

Best wishes,

Matthias

I use it with Raspberry Pi. The only issue is that openHAB starts really slow (about 3-4 minutes). Then everything works OK. However it uses almost all the available RAM memory and I have installed only the KNX and EXEC bindings. I guess it will fail with more bindings or other software running. My raspi runs with the old Debian image with soft float point, not Raspbian OS with hard float. This is because Oracle JVM doesn't supports hard float.

[Hannes Werner]

thank you very much for your reply. as I supposed...

Hi Victor

On Enocean, just for for my understanding, why did you prefer Encocean<->KNX instead of Encocean<->OH<->KNX?
Already considered Enocean plug to remotely switch a power socket?

I am myself wondering if I should prefer Enocean above Zigbee (e.g. plugwise devices)

[Victor Belov]

Hi Karel,

I didn't consider to do it through openHAB cause OH doesn't have
Enocean binding yet :-)
I also had a lot practice with Zigbee and I should say that though
Zigbee guys think of themself as an open standard and certify tons of
devices those devices are not cross-vendor compatible on application
level unfortunately. You can't use Control4 devices with Alert.Me and
vise-versa.
Z-Wave which is reported as a closed standard have 100% cross-vendor
compliance, the same is KNX and the same is Enocean. The only thing I
don't know about Enocean is if it is possible to extend the range of
network with some kind of repeaters, cause people who used KNX-Enocean
gateways reported they had to install several gateways in a house to
cover all Enocean sensors. So I would prefer Enocean and Z-Wave over
Zigbee for wireless rights now. Though Zigbee is great at transport.
And I'm still waiting for 6lowpan devices to appear on the market -
this will be really cool with new RFC for COAP.

I came across enocean repeaters today - so that is definitely possible.

so far, the easiest solution (to me) to bring Enocean to OH is to work with the Thermokon gateway. There is already a C# opensource implementation available, so learning from that would make the effort "reasonable" :-)
Advantage is that it is a device that is independent from the OH host (no USB dongle limitation or bad reception), you can plug it anywhere in the house and it comes with an external antenna to optimise coverage.

Hi,

Do you have a link for repeaters?

Hi,

Cool, thanks. I think that this gateway is the best way to go:
http://www.greenelectric.eu/STC-Ethernet-Gateway-Thermokon-Wireless-EnOcean-Transceiver
It is 2-way, so you can both read sensors and control actuators. If
someone develops Enocean binding with this gateway it's gonna be the
best thing in openHAB since KNX, probably :-)

Best regards,
Victor Belov

[Kai Kreuzer]

Hi,

I would also love to see EnOcean support in openHAB :-)

But the gateway that you mention is rather pricy - I would have hoped that a USB dongle like http://www.enocean.com/en/enocean_modules/usb-300-oem/ is enough. At its price of only 50 EUR, you can buy two repeaters and are still below the price of the gateway :-)

Kai

hi

[mbor...@googlemail.com]

Could you explain what Java -version and so on you installed?
Java is not supportet anymore by qnap..
I tried your explanation with the "ejre-7u21-fcs-b11-linux-arm-sflt-headless-04_apr_2013.tar".
I got the openhab up and running, but it dont find my Items.
(WARN  o.o.b.h.i.bus.HomematicBinding[:316] - No item found for <myadress>:1#VALVE_STATE - doing nothing.)
I used the same openhab-setup for my raspberry-pi with an "jdk-8-ea-b104-linux-arm-vfp-hflt-21_aug_2013.tar" installation of java.
here it works with no problems.
So I think it mustbe a problem with the java-version??

can you help me with this?
I#d like to run openhab on my qnap and not on my raspberry-pi

thanks alot.
Markus

Hi,

I'm also looking for a way to install openhab on my QNAP TS-412. Can you explain how you did this ?
