[EDIT] Displays if a new Node-Red update is available online, and update it from the Dashboard

This flow will search every 7 days if there is a new online version of Node-Red on https://nodered.org/.

If that is the case, [EDIT] : In this new version :

1. Indicates whether a new online version is available. Click on it to start the update : image

2. A wheel that turns to make you wait : image

3. When the update is complete, you can select:

  • either an automatic restart of NR
  • or (by default) a popup which proposes if you want to restart (or not) in addition to indicating the time taken for the update. image

4. After the restart indicates NR is up to date : image

New: to know the internal version of Node Red, you have the choice between manually entering the IP address of the NR server OR let it do it automatically by adding the node-red-contrib-ip node from the Manager palette.

The output of the array to online node, send :
msg.actualVersion is the running NR version
msg.onlineVersion is the online NR version on https://nodered.org/

Are there in addition:

  • A RESTART button image : if you want to restart NR for any reason :
  • A hidden DOWNGRADE button image : if you want to test with a previous version of NR

Tested on raspbian RPI 3B, RPI zero ...

Enjoy :slightly_smiling_face:

A similar question has been discussed in the following post:

Hi Andrei,
I read diagonally the topics which deal with this subject, but without succes. I will continue on this topic, with a little luck I will fall on @knolleary .

have you made progress with the high quality camera based on PI?
Thanks

Hi Chris, I could not even start that project. My trusted supplier for Raspberry Pi hardware halted the dispatching to our country, via regular mail, because of the ongoing health crisis. For the time being they are only dispatching via courier and that more than triple the final cost.

New in this EDIT : added update Node-Red button to Dashboard

Giving this a go now on a 1.1.0 Pi install

1st thing I noticed is that I deployed your flow and then opened up xxx:1880/ui and the dashboard appeared but it didn't show a new version was available so I thought it hadn't worked.

I went back to the flow to make sure i'd deployed and then came back to the dashboard to send you a pic when a few seconds later 1.1.2 appeared

So I pressed the update button and a message appeared saying updating but when I navigated away and came back - it wasn't there. Maybe add some status to main editing tab to say when update started and come back in 30 minutes?

Just passing this onto you for info

I put a delay of 5s to start the flow. This is probably why it took a long time to display the new update ?

have you tried the UPDATE NR button?

I'm still waiting to see if it updates - still currenly 100% CPU on my Pi so I'm thinking its not finished yet

I'm still waiting to see if it updates - still currenly 100% CPU on my Pi so I'm thinking its not finished yet
After >30 mins - still at 100% CPU - I'm re-booting my Pi

on my RPI 3B I noticed an installation time of about 35-45s suddenly I set a tempo of 50s before resetting NR.


Depending on the power of your RPI it may take more time and increase the tempo?
I would have liked the end of the installation to return a Flag to me but I am a beginner.

After reboot - it has upgraded to 1.1.2 :slight_smile:
This is on a PiZero which is much slower than a Pi3B

It took a long time ( > 1 min) to see the version number in the dashboard again and its telling me that there is a new 1.1.2 version (but now I am on 1.1.2 so I shouldn't see this)
image

Editor window shows this (but spent a long time say requesting (>1 min) on the http request node before showing this)

:+1:.
you let it do the reboot all by itself, or you forced it manually with : image ?

It does the job anyway: cool!

I'd forgotton that button existed - sorry :frowning: - I just assumed that the Pi was effectively stuck so I manually rebooted

If it monitored o/p 3 from the exec node it could indicate success or failure at the end and provide a popup to prompt for a restart.

It takes about 5 minutes on a Zero

If you want to redo the test with an earlier version of NR and optimize the settings (increase "delay 50s" node to 60 or 70s), here is the command for installation in the Terminal:
sudo npm install -g --unsafe-perm node-red@v1.1.1
image
this first "http request: http://192.168.1.54:1880/settings" asks the system for different information internal to your PI.
is it surprising that it takes so long? Unless he is stuck performing another very heavy task.

still a lot to learn, I will try, thank you @Colin

I'll wait till version 1.1.3 comes out and try again then

I'll make sure its at its normal 2% CPU before doing it next time

in the meantime, I will try to automate the reset of NR by scanning the output of the exec node. Rather than adjusting a tempo which can vary from one PI to another. Stay tunned :wink:

@cymplecy Simon, for testing you can always downgrade NR with
sudo npm install -g --unsafe-perm node-red@1.1.0

New update . See post #1

While I trying to get local version I get "unauthorized"
I have adminAuth enabled in the settings to access node red.
what now ?
