Another new addition to the library. node-red-contrib-ui-level. Stuck

Dashboard
1

Sorry folks.

Seems I have been away from NR a bit too long.

I have just installed the new: node-red-contrib-ui-level and it looks nice.
(I'm also kind of comparing it to the node-red-contrib-ui-lineargauge)

Anyway: NR version 0.19.4. Dashboard version 12.14.0 (Rebooted to get it all working.)

This is the code I have made to establish a base line:

[{"id":"6076c897.13684","type":"ui_level","z":"a6e58cf3.b2eaa8","group":"6214df15.ae6b9","order":0,"width":"4","height":"1","name":"VU test","label":"VU test","colorHi":"#e60000","colorWarn":"#ff9900","colorNormal":"#00b33c","colorOff":"#595959","min":0,"max":100,"segWarn":"30","segHigh":"60","unit":"x","layout":"sh","channelA":"","channelB":"","decimals":0,"animations":"soft","x":510,"y":730,"wires":[]},{"id":"8df9a257.c030c","type":"inject","z":"a6e58cf3.b2eaa8","name":"","topic":"","payload":"","payloadType":"date","repeat":"1","crontab":"","once":true,"onceDelay":0.1,"x":130,"y":730,"wires":[["d7dfc01d.90e3d8"]]},{"id":"d7dfc01d.90e3d8","type":"random","z":"a6e58cf3.b2eaa8","name":"","low":"20","high":"45","inte":"true","property":"payload","x":330,"y":730,"wires":[["6076c897.13684","80203c39.c8c388"]]},{"id":"80203c39.c8c388","type":"ui_text","z":"a6e58cf3.b2eaa8","group":"6214df15.ae6b9","order":0,"width":0,"height":0,"name":"","label":"Value","format":"{{msg.payload}}","layout":"row-spread","x":500,"y":780,"wires":[]},{"id":"6214df15.ae6b9","type":"ui_group","z":"","name":"VU","tab":"bab81a9e.75a6","order":3,"disp":true,"width":"6","collapse":false},{"id":"bab81a9e.75a6","type":"ui_tab","z":"","name":"Linear gauge","icon":"dashboard","order":35}]

This is the screen shot. (Excuse the other stuff on the screen. It is my "test" screen at this time.)
See the red area

Ok, I'm missing something.

But reading the docs, this is what I see as the "bare minimum".

Hi,
Any errors in browser console?

3

Sorry, but I don't understand what you mean.

How do I see the browser console?

If I have the debug output selected, there is nothing going on there.

I added the fan node only so I could swap inputs from the random number to just a one off input and see the result on the GUI also.

Just for clarity here are better screen shots.

At the GUI level it is still "blank" as per first post.

No I meant the browser developer tool console if you are looking the dashboard.

5

I'll admit I have no real practical experience at using it.
Though I may have poked about with it once or twice.

I know: Shame on me.
Could you help me get the information you want?

ITMT, I'll try at this end.

Is this it?

Useful?

Ok, let's try this one.

I cleared the log and rewired it for manual injection.

When I pressed the inject node (35) this error popped up/out.

I just hope I got the important stuff.

you should open the console from that page you need info from.

This is the best I can do from what you showed me:

activate condole tab and do browser refresh

This?

You are using the ngTouch module. 
AngularJS Material already has mobile click, tap, and swipe support...

I've moved it to it's own screen to try and reduce other stuff.

Yes, and it means no errors in browser console. :thinking:

12

So that other stuff I saw (earlier post) about the "null payload" when I pressed the inject node that I saw aren't relevant?

Do you have any other browser to try it out?
Even then, please provide info about your setup.
System info
Browser version

(NR version 0.19.4.
Dashboard version 12.14.0 )

14

Stand bye. Gotta install ...... Chrome?

Opera?

15

Lets start with chrome :slight_smile:

16

Drats. I actually found I had Opera installed.

Alas.....

Standby for Chrome

Chrome installed and running.

Oh, I changed the inject from 35 to 25. (Two buttons) just so I know the data I am seeing is real.

Let's go back to the system info then. Please provide.
And couple of questions in addition.
Do you used Palette manager for installing or did it manually?
Was the installation clean? (no errors)
Any errors (non regular warnings) on node-red startup log?
Have you tried to uninstall / reinstall the node yet?

19

Ok, installation:

Yes, from Palette manager.
It didn't say anything, other than it is/was installed.
No, haven 't tried uninstalling/re-installing.

Haven't checked NR startup log. (Sorry.) Shall look now.
(Have to remember where it is. I have it written down somewhere.)

stand bye (Sorry, corny, I know.)

20

Ok....

/var/log/ Nothing exciting to report.
The only node-red files are old

me@me-desktop:/var/log$ ll nodered*
-rw-r--r-- 1 root root     0 Oct 15 06:59 nodered-install.log
-rw-r--r-- 1 root root 44337 Oct  6 08:12 nodered-install.log.1
me@me-desktop:/var/log$

Uninstalled and reinstalled.
(NO reboot.)

Same.

Ubuntu, not RPI.

Anywhere else for NR logs?
