[SOLVED] HABPanel sluggish

Bigger problem is not loading the items but the event stream. The addon also does filter events that happen for the items present in the group. It also filters device changed and update events thus reducing processing power required for javascript on habpanel side.

Ah that’s what i was missing.

i have succeeded in building habpanel, so updated the zip file (https://www.dropbox.com/s/hy8kb2laphliqbn/openhab2-addons.zip?dl=0) with 2.5 version of the habpanel. Enjoy and do let me know if it helped you!

I’ve downloaded the file and tried it on 2.4 and get the following

I downloaded the 2.4 version this afternoon but seems the 2.5 and the 2.4 are the same.
Once I out the jars in the addon folder it breaks HP all together.

Any chance of getting a specific 2.4 version please?

Hi @arctus,

I just installed your modded habpanel but it does not work for me (I am on the latest snapshot #1689).
When opening Habpanel in a browser it states “Connection lost, trying to reconnect” and the log is flooed with the following error message

2019-09-15 21:29:46.859 [INFO ] [er.internal.web.FilteredItemResource] - Received HTTP GET request at 'items-filtered'

2019-09-15 21:29:46.870 [WARN ] [org.eclipse.jetty.server.HttpChannel] - /rest/items-filtered

javax.servlet.ServletException: javax.servlet.ServletException: org.glassfish.jersey.server.ContainerException: java.lang.NoSuchFieldError: editable

Any idea?

@CDriver these are the libraries I use personally on 2.4 and they work without any problems: https://www.dropbox.com/s/6jgqktsqo8ix1ka/habpanel-2.4.zip?dl=0
@Chrishab it seems there were too many changes to openhab after my last compilation for 2.5, these are the libraries compiled for latest snapshot: https://www.dropbox.com/s/2mpdydkzxprrs3b/habpanel-2.5.zip?dl=0

Thanks. I’ll try this evening.

Thanks for this @arctus. Would it be possible to have the filter group name as a user-defined parameter? Maybe via paper UI?

arctus · September 16, 2019, 9:07am

It is possible, but as this was done mainly for me - I did not bother much If this plugin gets recognition, we can make this as a parameter.

smar · September 16, 2019, 9:15am

That would be great.

BTW, I am still getting the connection lost message using your latest files, running on 2.5.0M3.

Kim_Andersen · September 16, 2019, 9:56am

It should!

The latest version of this (it is the first, that i tried) does not work for me… I´m on oh 2.5 snapshot #1665 (i made update at 19.08.2019).

I get an empty habpanel. I added all of my lights to this new group. And the habpanel with my lights on it also was empty.

arctus · September 16, 2019, 10:25am

just to confirm, you are using both the files from the zip: habpanelfilter and habpanel? Also, when you say empty - do you mean that habpanel does not even show any html markup, just empty screen? If it does not show the markup, that means it is not connected to the habpanel that I provided - if it would not work, you won’t see any values for the items, but html markup would still be visible.

arctus · September 16, 2019, 10:26am

Is this a constant message or habpanel works, but this message just appears from time to time?

smar · September 16, 2019, 10:58am

Constant message. Habpanel does not show any items. I just get the panel selection screen. Putting the original habpanel jar into the addons folder immediately brings all items and panel layouts back again (albeit with the usual performance issues)

arctus · September 16, 2019, 11:10am

thanks, are there any javascript issues in the development menu?

smar · September 16, 2019, 11:39am

Thanks and yes, the following are constantly repeated:

Error loading openHAB items… retrying in 5 seconds openhab.service.js:64:25

arctus · September 16, 2019, 11:45am

This one is definitely not mine.

Btw, what do you get when you go to http://youropenhab:8080/rest/items-filtered (replace your openhab with your openhab address)? Did you see any problems when installing habpanelfilter addon?

smar · September 16, 2019, 12:09pm

I’m getting:

HTTP ERROR 500

Problem accessing /rest/items-filtered. Reason:

Request failed.

No, nothing untoward showed up in the logs.

arctus · September 16, 2019, 2:09pm

As suspected there is something wrong with the habpanel filter and not habpanel, can you check whether it is listed in the installed bundles in karaf?
