OpenHAB binding

[Pauli Anttila]

Hi All,this forum has been very useful for me, so like it to inform that I have recently developed OpenHAB binding for IHC / ELKO LS controller. I not understand a word in Danish, but luckily google translator works very well OpenHAB is open source home automation system. I discovered OpenHAB half an year ago, when I researched system to expand my current IHC system. OpenHAB is based on OSGi and it's looks very promising.Codes are already available on OpenHAB clone's repository, but If there are any interest I can post pre builded binding as well and some information how to configure the binding.Regards,Pali

Hello PaliVery interesting.It seems that you have done a very thorough job ...Thumb's up

[Pauli Anttila]

I've got few emails about the binding, so I just posted some quick information on the OpenHAB's forumCheers,Pali

[Mikkel Skovgaard]

Great work!

[Jens Vestergaard]

Nice

[Pauli Anttila]

IHC / ELKO LS binding is now included to OpenHAB's official repository. Before OpenHAB version 1.1 is officially released, latest version could be found from snapshot buildings (link).There is also wiki page for binding available.Br,Pali

Nice work indeed Pali.

 

I have got it installed on my beaglebone black on an Ångstrøm Linux.

But I have this problem when trying to parse my big project file (2.4 MB) it just hangs there for ages.

Then when I try one of my earlier project files that are smaller (1 MB) it gets through it and loads it. but it I can't connect to the OpenHAB server after this.

If I then try to disable the IHC binding after this and tries to start OpenHAB it is not able to start.

The only thing that I have found until now that fixes this is to unpack OpenHAB again in another folder and start again.

After this it starts alright again but after I have loaded the IHC project file again after having enabled the IHC binding it doesn't work again.

If I have a fresh OpenHAB and enabled the IHC binding but put in a wrong IP og password and there for not loaded the project file it starts up in demo like it should.

But after the load of the project file I can't get it to work again.

 

Thanks for your feedback in advance

 

Kind regards

Jesper

Hi Jesper,

 

1) Which version of OpenHAB are you using? 1.2 version contains bug in ihc binding, but bug is not related to startup. Anyhow this bug is fixed on nightly buildings (https://openhab.ci.cloudbees.com/job/openHAB/).

2) Have you tried to run openhab on normal pc (windows/linux/osx). If not, you probably should first try to get it work on that, before beaglebone. How much RAM is on your Beaglebone black, 512MB?

3) You should enable debug logging on openhab to get more information about the problem.

 

My project file is 2,6 MB and I don't have any problems. Parsing take few seconds.

 

-Pali

 

FYI...I have run openhab now 9 month without single problem. My openhab is installed on mac mini, which i have need to boot few times during 9 month for other reasons. There are also other users using ihc binding. Probably from this forum as well, because names sounds danish.

[Jesper B]

Hi Pali

 

1) Yes im using the version 1.2.1 bindings from the 16th of April.

2) Yes I have just tried to run it  on my mac air and it seems to run well - it is much faster   . My BeagleBone Black is equipped with 512 MB of RAM as you say.

3) I have run it in debug mode i usually does that to get more info. 

 

But just a sec. I have just tried to run it again after having tried it on my mac and now it works on my BeagleBone Black.

I don't know what you did Pali but something worked  .

 

Next step will be trying out to get info forth and back and try to control something.

 

Thanks all.

 

I will get back to you with progress or issues  .

 

Kind regards

Jesper

[Pauli Anttila]

You definitely should use v1.1 or latest nightly build, because v1.2.x branch does not contain bug fix yet. Problem on v1.2 is unfortunately so fatal, that e.g. switch items does not work correctly. Any functional change is not done since v1.1 on ihc binding.

 

Cheers,

Pali

Hi Pali,

 

I have been trying to do a use the Setpoint item with no luck.

 

Setpoint Setpoint_GF_Living "Temperature [%.1f °C]" <heating> (GF_Living, Heating) {ihc="0x291b14"}

 

do i need add Setpoint somewhere else ?

 

 

got it now.. 

 

i sitemap :

Setpoint item=Setpoint_GF_Living step=0.1 minValue=15 maxValue=30

Can any one give me detailed description on how to import the certificate to Java on a win 7. I must do somthing wrong when i start openhab it comes with an security error by connecting to IHC. 

 

 

C:\OpenHab\openhab-runtime-1.3.1>keytool -importcert -alias ELKO -file c:\openha

b\ihc.cer

Enter keystore password:

[Gilbert]

Kan du ikke bare godkende den i ie eller Firefox, tænker og din path til cert måske skulle være noget i denne stil "C:\Program Files\Java\jdk1.6.0_32\jre\lib\security\cacerts" medmindre du har ændret det

[Togi]

Please see picture on how I imported the certificate to the keystore. Note that while I wrote the command I was "standing" in the "C:\Program files\Java\jre7\bin"

 

 

By the way OpenHAB has been working great for me as well. Had a few issues in the start but have been running smoothly for months now. Great thanks to Pauli for his contribution with the binding.

[FrankGP]

Thank you very much for the ansver I found the solution in the picture you send. I had stored the certificate in the wrong Java version instead of JRC I had used JDK. Now it works fine. 

[Gilbert]

Anyone who already have some defined rules for IHC <-> squeezebox 

[JanneSjo]

Hi

 

I have installed OPEN HAB and gotten the demo to work. I get info below when starting OPEN start.bat

 

Does this mean everything is ok and that I now  shouldto start adding something in items file?

 

or should I see somewhere that OPENHAB have fetched my IHC projectfile from controller?

 

regards Janne

Hi Janne, yes i looks like that all is startet, and good.

Did you configurer everything in openhab.cfg file

[JanneSjo]

yes like this I guess I should use https:

 

So then I should just try then to get something to work...

 

########################### IHC / ELKO LS Binding ####################################
#
# Controller IP address
#ihc:ip=https://192.168.1.xx/

# Username and password for Controller
#ihc:username=userid
#ihc:password=userspassword

# Timeout for controller communication
#ihc:timeout=5000
 

[Gilbert]

yes uncomment the settings you need and edit them so they match your ihc.

 

########################### IHC / ELKO LS Binding ####################################
#

ihc:ip=https://192.168.1.2

[Gilbert]

Janne,

 

with Openhab it is also really easy to chart/graph of your heating an etc.

 

 

[JanneSjo]

yes uncomment the settings you need and edit them so they match your ihc.

 

########################### IHC / ELKO LS Binding ####################################

#

# Controller IP address

ihc:ip=https://192.168.1.2

# Username and password for Controller

# Timeout for controller communication

ihc:timeout=5000

 

got excited getting so far with this but gave up at 0230 in the night - and today I with help from your post realized I missed uncommenting.....  no wonder nothing worked

[JanneSjo]

Got some error "Controller is null...." when OPENHAB tried logging in to IHC controller.

 

What could the reason be for the error in OPENHAB?

 

 

in firefox, going to the IHC homepage via http://192.168.x.x  works and then clicking e.g. Sceneview fetches the .jnlp and it connect to https://192.168.x.x:443 and Sceneview works

 

if I in firefox try to open page https://192.168.1.60/  or https://192.168.1.60:443  I get the error

403 Forbidden

Rogatkin's JWS based on Acme.Serve $Revision: 1.36.2.1 $

 

in controller I have DNS set to 192.168.1.1  = my router IP if that matters

 

 

below is log from OPENHAB

Hi Janne,

 

You should define just a ip address not a whole url in config.

 

# Controller IP address
ihc:ip=192.168.1.60

 

And it's normal to get "403 forbidden access" error if you try access https://192.168.1.60 url directly by firefox, because controller does not provide any web pages by https.

 

Next you probably need to import controller TLS certificate to java trusted list. See further details from http://code.google.com/p/openhab/wiki/IHCBinding.

 

Regards,

Pali

[JanneSjo]

Thanks!

 

the error was the HTTP before IP Address

 

using

# Controller IP address
ihc:ip=192.168.1.X

 

made it work!

 

now my test IHC lamp is updated in toilet - although not using timer . since I am monitoring resource id for output - should probably use resource that is used to toggle on/off with timer  in IHC instead

 

but I do get an error when logging in to IHC controller via Service View - see below. I had to change login to same user as OPENHAB user

 

NB  even with error OPENHAB works and can update lamp etc

 

questions:

can OPENHAB user be a normal user or does it need to be a administrator user?

 

 

is error below due to simultanious log in via serviceview with same userid - or some other error?

Most probably user need to be a admin user. I have never tested with normal user rights.
