I tried to enable the context storage in Node-RED: I opened the Node-RED settings page in cockpit then changed the `Context Storage` section as follows

contextStorage: {
default: {
module:"localfilesystem",
config: {
dir: "/var/lib/revpi-nodered/.node-red/",
cache: true,
flushInterval: 10 ...

Sven, I added user nodered to the "video" group, and created a directory `/var/lib/revpi-nodered/Videos` where I loaded all the videos I want to play: nevertheless, when I run the command
mpv --fs /var/lib/revpi-nodered/Videos/video1.mp4
I do not see anything on the screen and get the following ...

Thank you very much, Sven. I'll apply your solution soon as possible. By the way is there also a "printer" (maybe "cups") group? I am asking this since the flow I am designing need also a printing part that has not been tested yet (due to momentary unavailability of the USB printer), so I wonder if ...

An update : if I restart the flow, I get the following message

Hello to everybody.
I have just purchased a RevPi Connect 5 and, following the standard RevPi procedure, I've enabled Node-RED, updated all the software and configured the RevPi DO in order to enable the outputs and inputs I need for my application. Initially I thought I should enable also the Node ...

Hi crismancich,
I solved the problem by using your suggestion in a ladder structure, precisely the one shown in the picture below:

The input of this submodule is activated at start-up: the shown subflow then takes a screenshot of the input status and send it ...

HI crismancich,
Thank you for the flow you suggested: do this implies that it is not possible to "take a picture" of all inputs jointly, for example by using some initial state of the node revpi-multiple-input ? I mean, if I need to know the state of all inputs at a given time, possibly in the form ...

The title says all: I'd like to know if a message is generated at turn on to make a Node-Red system aware of the status of DIO inputs. I see that when an input changes, the associated payload property assumes a string value "1": however the other properties have an integer 0 or 1 value, thus I'd ...

I had the same problem last week with my laboratory Core 3+: then I flashed the Buster image and it now works correctly.

Hi Amar,
I just tried your solution: it works perfectly, as my workaround does. Thank you very much.
