node-red-contrib-homekit-bridged: Error: This callback function has already been called by someone else...

Hello guys,

thank you very much for the large progress you have made with version 0.6.0. I’m really exited how linked services work now. Right now the only issue I have with that is I got a lot of this message in my node-red-log:

18 Mar 14:35:26 - [error] [homekit-service:XXXXX-XXXX-temp] Error: This callback function has already been called by someone else; it can only be called one time.

It looks like this is cause by re-deploying modified flows on node-red but I haven’t figured out right now if this is based on changes on node-red-contrib-homekit-bridged-nodes or on changes of any other nodes as well.

Any ideas?

Please update to new version 0.6.1 using node-red. Then please retest this bug if it’s still occurs.
