Cast Hue Bridge Exception [message #1429688] Tue, 23 September 2014 11:44 Go to next message

Hello all,

I am using the Hue Binding as an example to better understand how to develop a binding, however i get the following exception when i declare a Hue Bridge in the .things (like this: hue:bridge:home [ ipAddress="1.2.3.4" ]):

16:38:36.796 ERROR o.e.s.c.t.i.ThingManager[:297] - Exception occured while calling handler: org.eclipse.smarthome.core.thing.internal.ThingImpl cannot be cast to org.eclipse.smarthome.core.thing.Bridge

you need to put the "Bridge" keyword at the beginning of the line in your things file. The DSL parser is not clever enough to check whether a thingTypeUID is a bridge or a thing, that's why you have to manually mark it.

+1

Just spent the last hour or so trying out to figure the same

That being said, in the DSL, how do you couple Things to a defined Bridge?

Maybe it is worthwhile to post the complete .things for the Hue binding with lamps defined in the DSL and not sourced from the Discovery process
