Wrong ip value causes node red to crash

[Henkkas52]

I accidently made a wrong ip address entry, that causes node red to crash!!

To add a bit context, in your node, there is no error handling around the gree client so errors in async code crashes node-red. These should be handled/caught and fed back to node-red via node.error(...) as documented in the node-red docs.

Thanks.
