Getting a bunch of these on my installation:

"TypeError: Cannot read property 'addListener' of undefined"

It says "No connection" not sure what this can be?

When NR tried to set up one of the event nodes there was no connection to HA that caused the error to be thrown. This should be handled better.

Does this have one connection for every node? It seems like they are reaching a limit on my house automation. Not working properly all the time. It worked with the old version (not websocket).

There's only one WebSocket connection to HA no matter how many nodes you have placed on the workspace.
