Zoneminder binding

mr_eskildsen · June 18, 2017, 2:37pm

Can yopu check your log to see if you have a line like this:

[MONITOR]: Configuration for Thing 'zoneminder:monitor:xxxxxx:monitor-1' is not loaded correctly.

The ‘xxxxxx’ should be changed toi the same id as your bridge?
I am quite sure that this is somethineg that appears when something isn’t started correctly. Somehow it seems like things can happend in a order so that it doesn’t work.

mr_eskildsen · June 18, 2017, 2:42pm

Nope, I really believe that your connection is stable. It is something in the binding that falsely indicates an unstable connection. If you take a look at the debug log all http calls is logged with returd code. I bet all of them returns 200 (=not wrong with your connection).I see somewhat the same problem, so I guess it is related to initialisation.

Mike_Bagdanoff · June 18, 2017, 2:45pm

not seeing that in the log, I did notice this line though:

[MONITOR-1]: refreshThing(): Bridge 'zoneminder:monitor:756ae518:monitor-1' Found for Thing 'zoneminder:monitor:756ae518:monitor-1'!

is that a bad log message or does monitor-1 have itself as its own bridge?

mr_eskildsen · June 18, 2017, 2:47pm

Seems to be an error in the logmessage, if it isn’t an error message, you shouyldn’t worry

mr_eskildsen · June 18, 2017, 2:54pm

This is really strange, My openHAB build i #929, I am having somewhat the same problems. I have now build a addon from sources and when running in debug env. there is no problems, when running the same addon in #929 I see problemjs. I will try to update to latest openHAB build. Hopefully that solves the problem.

Mike_Bagdanoff · June 18, 2017, 3:07pm

I’m hesitant to update to the latest as a there seems to be a breaking change in the latest snapshot:

mr_eskildsen · June 18, 2017, 3:10pm

Thanks for notifying, would be a problem for me too,a s I am using Z-Wave

mr_eskildsen · June 18, 2017, 4:13pm

I have updated to latest build and now it starts to connect (consistently) as expected. The strange thing though is that in console it is still reporting Build #929, so I am uncertain if the upgrade is done completely. Also Zwave seems to work, but haven’t testet in details…

chris · June 18, 2017, 7:21pm

The breaking change only impacts the development version of ZWave at this time, and hopefully in 30 minutes or so I’ll compile up a new one anyway…

I don’t restart openHAB very often, but when I do, the zoneminder binding often fails, giving me a series of messages like this:

2017-06-26 09:08:12.862 [ERROR] [andler.ZoneMinderServerBridgeHandler] - [MONITOR]: Method 'refreshThing()' for Bridge failed for thing='zoneminder:monitor:zm:monitor-5' - Exception='java.lang.ClassCastException: org.openhab.binding.zoneminder.handler.ZoneMinderThingMonitorHandler cannot be cast to org.openhab.binding.zoneminder.handler.ZoneMinderBaseThingHandler'

The only solution I’ve found that works is to manually delete all the cameras and zoneminder server Things, restart openHAB, and then re-add them.

Anyone else seeing this?

I’ve recently updated to the 7/1 snapshot and I’m seeing better performance until this happens:

06:26:08.892 [ERROR] [andler.ZoneMinderServerBridgeHandler] - [MONITOR]: Method 'refreshThing()' for Bridge failed for thing='zoneminder:monitor:756ae518:monitor-1' - Exception='java.lang.NullPointerException'

Which seems to trigger sometimes when a command is sent to the Thing to change its state to Movies or Nodect (the only thing my rules do when someone comes up the driveway). The logs get full of this every two seconds and stopping/starting the bundle in karaf is the only way to fix it.

Mike_Bagdanoff · July 7, 2017, 4:57pm

These refreshThing errors seem to happen any time the camera changes state on its own to. If the monitor is set to mocord, the errors start if a recording is triggered from zoneminder due to motion. Then the log is filled with these errors every 2 seconds

mr_eskildsen · July 14, 2017, 8:35pm

Thanks a lot for you observations, I haven’t had time to look at them due to vacation :-). I will try to find som time to look at the code with your observations in mind.

crankycoder · August 7, 2017, 1:36pm

Hey Rich,
I was wondering about zoneminder / motion as well. This is what I ended up doing.

I have a VM running motioneye as my central box. Then I use a raspberry pi to be my remote camera.

I have motioneye do the motion detection even on the remote cameras and fires off motion detect scrips to openhab.

I am currently working on a newer version of the camera using a raspberry pi zero / POE / IR cut filter and IR leds.

whopperg · August 16, 2017, 8:05pm

Hi @mr_eskildsen,

i’ve also got this wierd problem after upgrading to oh 2.2.0 build 1014 (online). Zoneminder Version is 1.30.4

I’ve set the main zm language to en_gb and also the language for the user to en_gb:


Username	Language	Enabled	Stream	Events	Control	Monitors	Groups	System	Bandwidth	
openhab	    en_gb	    Yes	    View	Edit	Edit	Edit	    Edit	Edit	High

Reinstalled the binding multiple times, also restarted everything (oh and zm):

Thanks for your logs, seems like I have to do some debugging. Unfortunately I have been quite busy with other things lately, first of all a broken disk in my fileserver - ended with a large cleanup project…

trumee · August 17, 2017, 12:08am

Unfortunately, my ZM server goes from Running state to Stopped state if i do an Operating mode change from Modect to Monitor. I have to then login into ZM webserver, and change the ZM state from Stopped to ‘Start’.

Is it possible to change the ‘state’ of the ZM server in rule?

Here is a short log

Hi! Did you check the ZM log? Also the message log?

whopperg · August 17, 2017, 4:42am

@mr_eskildsen: oh, doesn’t sound fun… hopefully you didn’t lost any important data! So good luck with fixing your server!

trumee · August 17, 2017, 11:01am

@whopperg, yes the logs do show that zmc has stopped working. It is some sort of race condition which cause zm to shutdown. Here are the details of it.
