Hi, great article thanks.
After a few years it’s time to upgrade nodered, npm etc etc on a raspberrypi 3b.
Do you have any articles on how to do that please?

Hi, I tried to install node-red on my Raspberry 5 but I get this warn when I start node-red
31 Mar 12:27:08 – [info] Node-RED version: v3.1.8
31 Mar 12:27:08 – [info] Node.js version: v18.20.0

31 Mar 12:27:10 – [info] Started flows
I do not understand why it says Encrypted credentials not found. Moreover if I enter the command sudo reboot it seems not to be executed since the green cursor is not followed by the usual bruno@raspberrypi5: However if I type Pi5_IP_address:1880 the node-red dashboard opens Could you help me ? Thanks

Hey Guys, got a problem with this one. I’ have an older version running on a Rpi2b, and just aquired a 3b and planned to use it as a backup. Things have changed since the first one, like Node Red being on node-red 3.2 with the security features, so when I get through the admin init stage, and type node-red-start in the terminal window, I get “bash: node-red-start: command not found”. Not sure where to go with that?

Hi.
Next week, we’ll be publishing two getting started guides about Node-RED.

Probably a great article but… what is Node-RED and why we need it (or not). I don’t think mentioning some usefulness of it at the end is the right way. I got it, you have to keep it short and to the point on how to install it. In this case a link to external source would be more than enough.
