This node has a number of long standing unresolved issues - [Issues · urbiworx/node-red-contrib-hue · GitHub](https://github.com/urbiworx/node-red-contrib-hue/issues)

It also hasnt been updated in over 9 years.

Have you tried [other hue nodes](https://flows.nodered.org/search?term=hue&type=node)?

PS: to start node-red, use safe mode - then you can uninstall that bad node.

```auto
node-red --safe

```

Also, please give this node 1 star [in the flows library](https://flows.nodered.org/node/node-red-contrib-hue)

yeah I saw it hadnt been updated in 9 years. but when i looked at the nodes it were the one that made the most sense to use.

I will go and give it 1 star in the flows libary

I will try and remove it with the bit you texted.

What happens when you run  
`node-red --safe`  
Note there is a space and two dashes.

Your flow credentials file is encrypted using a system-generated key.

If the system-generated key is lost for any reason, your credentials
file will not be recoverable, you will have to delete it and re-enter
your credentials.

You should set your own key using the 'credentialSecret' option in
your settings file. Node-RED will then re-encrypt your credentials
file using your chosen key the next time you deploy a change.

That is not a well behaved node at all. Go into the .node-red folder (that is important) and run  
`npm remove node-red-contrib-hue`  
Then restart node-red.
