I can't use that feature (yet) because my settings.js does't have the "httpsRefreshInterval".
I'm still investigating but it is due to the fact that httpsRefreshInterval requires "Node.js 11 or later".
My RPi4 had an older version of Node-RED, Node.js and npm.
I succesfully updated node-RED (using the instructions here [https://nodered.org/docs/getting-started/raspberrypi] ) but npm and Nodejs update are failing.
My current configuration is:
[info] Node-RED version: v1.2.6
[info] Node.js version: v10.21.0
I tryed various way to update Node.js and npm with no success....Any idea ?
Thanks!
