Ember EM35x Coordinator creates lots of warnings

  • Platform information:
    • Hardware: Raspberry 3
    • OS: Openhabian
    • Java Runtime Environment: which java platform is used and what version
    • openHAB version: openHAB 2.4.0 Release Build

I have installed the Zigbee binding with the Nortek Security Control HUSBZB-1. Works fine, but now my openhab.log is flooded with warnings from the Zigbee binding, e.g.:

2019-03-14 17:46:56.017 [WARN ] [.core.thing.binding.BaseThingHandler] - Handler EmberHandler of thing zigbee:coordinator_ember:66825950 tried updating channel rx_dat although the handler was already disposed.

Warnings for other channels are generated, too, and they appear approx. every 30 seconds. I could just don’t care as everything works fine, but perhaps I could get a hint what it means and how it can be solved. As it refers to BaseThingHandler it might be something deep in the guts of OpenHAB.


Do you get the warnings after restarting OH? There have been a lot of very good updates to the binding since 2.4 was released, especially for Ember, so if you have troubles, think about upgrading.

That was it. Restarting the service helped.
