Although I have previously _complained_ about it and so on. I have now reinstalled the latest version to server a purpose.

Monitor usage of a USB stick.

This is the flow - basically.

Non standard nodes needed:  
`node-red-contrib-os`  
`fan`  
`gate`  
(and)  
`ui level`

Walk through:  
_input_ selectable between daily or every _n_ seconds.  
pulse `node-red-contrib-os` node to get used disc (%) of USB stick.  
convert to number.  
display on `ui_level` node. (3x2) vertical.  
Other stuff there that if over _x_% used generate message about USB getting full.  
There is also an `inject` node in there for testing. (I'll get back to that soon)

This machine is on 24/7.  
This morning I looked at the page and this is what I get:

 ![Screenshot%20from%202019-09-18%2006-44-34](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/2X/9/922bbbb30cbcdc1489d39be0270a31100db6b429.png)

Which to me shows 100% in use.

Pressing the `inject` node it changes to this:

 ![Screenshot%20from%202019-09-18%2006-54-00](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/2X/f/f4b4eb2ab0edc87dab198876bc5a13e68bab0db9.png)

Sorry, but what am I missing that if I don't look at the page, it _defaults_ to 100% full display?

You hit a bug. 🙂

Sorry.

I don't want to really say "bug". I've been caught a few times with my pants around my ankles because of something stupid I did.

This is what is happening. I'm not sure I'm not missing something or not.

(`ui_control`?) (😜 cheeky wink)

This is something you should never see.  
_value = 1 but shown as 100%_  
Definitely bug. 🙂

Thanks for the update.

Installed and working a lot better now.
