Error: (BridgeFound)::Object reference not set to an instance of an object.

[wcross]

I keep receiving the error in the Subject every five minutes. I'm currently running HS3 with a single Hue Bridge. The plug-in detects the bridge and everything seems to work fine. Not sure what this error is for/from...

Could you send me a trace of the plugin? Somehow there will be wrong reference in your situation, I hope to be able to find this in the trace so we can solve this.

For a correct trace, please follow these steps:

1. enable the detailed trace and log to file options in the configuration of the plugin
2. Stop and start the plugin, so we have the start of the plugin included in the logs
3. let the plugin initialize and let it run until it logs the error in the HS3 log.
4. Then disable the detailed trace and log to file options.
5. In the Logs subdirectory of your HS installation directory you will find JowiHue.log, please send me this file?

Send the log to jowihue at ziggo dot nl?

Thanks,

Wim

I'll spare you the email, as I ran the log (snippet below) and I figured out the problem, or at least the cause of the error. I have a HA Bridge running to enable control of lights from my Logitech Harmony. Your plug-in is detecting the bridge, but is unable to communicate with it, hence the error.

Somehow the discovery of a HA bridge keeps changing. Though I did catch these emulators but every now and then it seems something changes and the plugin trips over it.
You you try and get the description.xml for me, so I can check in the plugin if I can catch it again?

f you go to 192.168.1.61\description.xml, it should open a text file showing contents?

I think I am seeing a possibility to recognize it, comparing with my Philips Hue bridge here. Thanks!
