deployment of openHAB on embedded linux device and new binding...

[dcand...@gmail.com]

Hi all,
i'm new on openHAB forum.

I'd like to deploy openHAB on an ARM powered device with linux embedded.
This device, named HomePLC.Linux, is a domotic PLC and its domotic network
is based on rs485 bus and on a proprietary protocol named XComm++.

My intention is to exploit directly the home automation system provided by the
device and use it as the basis for integration with other technologies.

HomePLC.Linux comes with the native library to access the PLC memory and the
interfacing (JNI) Java Class.
Currently I have made ​​my own system to read data from the sensors,  execute
commands to actuators and an event generator based on changes of registers.

I tried to start openHAB on the device but not all bundles were active, many
resolved and many starting, ending with... (sorry for the long list that will follow)
I saw the error "UnknownHostException" and i'm trying to solve it.

I'm trying to create a binding for HomePLC but I have many problems currently
and I have a lot to study because it isn't all clear to me.
I was wondering if i can use a reduced/minimal version of openHab to test the proper
initialization of the system.

Thanks.
Danilo

Hi, i solved my UnknownHostException error and i'm now able to
connect to the demo with browser.
Actually the following bundles remain in the state Resolved

  192|Resolved   |    4|openHAB Script Engine (1.3.0.201308140307)
  201|Resolved   |    4|openHAB Serial Transport Bundle (1.3.0.201308140307)
  223|Resolved   |    1|openHAB RRD4j Persistence Bundle (1.3.0.201308140307)

in fact, I get the following  runtime errors

15:47:47.790 ERROR o.o.p.r.internal.RRD4jService[:252] - Could not create rrd4j database file '/openhab/etc/rrd4j/Heating_GF_Toilet.rrd': Invalid argument
15:47:48.112 ERROR o.o.p.r.internal.RRD4jService[:252] - Could not create rrd4j database file '/openhab/etc/rrd4j/Window_GF_Toilet.rrd': Invalid argument
15:47:48.175 ERROR o.o.p.r.internal.RRD4jService[:252] - Could not create rrd4j database file '/openhab/etc/rrd4j/Heating_GF_Living.rrd': Invalid argument
etc...etc...

Many other bundles remain in Starting/Resolved state.
Do i really need them? I don't have so much space available on my embedded device.
I'd like to preserve it.

Thanks.
Danilo

Hi Danilo,

You won't really need all bundles that are included in the runtime, but I do not have any details of what you could possibly remove.

I actually planned to reduce the set of bundles to the absolutely minimum with issue https://code.google.com/p/openhab/issues/detail?id=138.

This should make openHAB more optimized for embedded hardware like the RaspPi (what it currently isn't).

Regards,

Kai

Hi all,
I made a mistake adding an answer sending to Kai a private message
so I post below his reply.

Thanks again Kai.

Hi Danilo,

There is a programmatic way to define items, rules, etc… ?

Yes, there are different options:
1. As the models are EMF models, you can use EMF in a programmatic way to add new models in the model repository
2. You can implement things like ItemProvider and SitemapProvider and directly add your own items or sitemaps to the system.

Regards,
Kai

Hi Kai,
thanks for your reply and... great project!!!

Fortunately I was able to deploy all 1.3.0.SNAPSHOT with demo bundles (without TTS - it doesn't fit).
My device has also an external sd memory (not for system startup) so i'm planning to route logging
and persistence on it... when I will be able to understand how :-)

I'm also trying to take confidence with xText, xBase but i'm new to them.
if I understand correctly all model bundles bridge from dsl to java.
There is a programmatic way to define items, rules, etc... ?

Thanks again.

Hi Danilo,

I try to run OpenHAB on OpenWrt on my TP-LINK TL-WDR4300 (which run on OpenWrt Attitude Adjustment 12.09). I got also error message about UnknownHostException

ERROR in ch.qos.logback.core.util.ContextUtil@732627d0 - Failed to get local hostname java.net.UnknownHostException: OpenWrt

at java.net.UnknownHostException

I wonder how did you fix this error. Can you please send me how fix this problem?
