i've just finished a bigger project using 4 PTZ Cameras. Project works. Just 2 questions about handling.
my project had 4 cameras including, but only 1 was available. The other 3 PTZ nodes steadily send error-messages which made atherwise reading messages difficult. Is there a way to suppress messages from these nodes?
After finishing the work i deleted the nodes, deleted flows and ui-entries. But after addind new nodes for a different project and deploying them nodered found some more unused entries. And the PTZ nodes, also deleted, still produces error messages. Is there a possibility to make 'Tabula rasa', a clean enviroment ? Or can this be added to a next release?
All the best,
If they are errors (not warnings) and the node was written correctly, you can suppress these using a catch node pointed at them.
- Use projects mode (a setting in settings.js)
- Startup node-red with
-u parameters (e.g.
node-red -u /my/new/project/)
You could also just delete your userDir folder completely, restarting node-red will recreate a blank environment for you.
Thank you for your replies, i will try that tomorrow.
@Steve: When reading your reply i'm not shure wether it was an error or a warning - simply the camera was not present.
Well, it's an error, but catch does not help.
In which case, you should contact the author and ask that they catch errors and relay them to node-red using the mechanism
node.error(error, msg) or introduce an option to either send errors out of a 2nd output or to suppress them.
