Hi folks.
This is a flow (two parts) that you can put on machines.
The idea is that if you are modifying the flow often, it is sometimes possible you destroy something.
This (these) flows allow you to back up your node-red flow.
As well as shut down or restart a remote machine.
In this example I have used the LINK to join the two parts, only for simplicity and leave HOW you connect them to yourself. Though MQTT is probably the best way to go.
Also!
It needs a script which is in a comment node at the bottom with instructions.
So: there are three nodes - I didn’t bother with buttons as they would only complicate the layout - you press one to SHUT DOWN the remote machine, another to REBOOT it, and the third to back up the flows.
I know it isn’t the best written, but I am new to NR and have got this little thing working.
It is handy for working on remote machines.
I hope you can work out what I mean in the somewhat attempt at writing the instructions both here and in the flow.
Oh, and in the two nodes: SHUTDOWN and REBOOT you will have to enter the name of the machine. Sorry I didn’t delete my names before posting.
But I am sure you will get the idea.
Likewise you will also have to edit the SHUTDOWN, REBOOT and BACKUP injection points with the machine’s name.
Flow below.

Yeah, sorry.
