Context to file creating temp files

General
1

Hi,

I have created a flow which has 24 context variables saved to file.
When I browse to the context directory of that flow (Raspberry Pi with Raspbian Buster), I notice that every minute a tmp file is created.

/home/pi/.node-red/context/8b2862b307a292bb

What is causing that?

I have injectors in the flow that restore the context values to the dash board objects after restart node-red or reset the raspberry, but repeat is set to "none" the only inject once after 0.1s

How are you saving the context variables to file? Using a file node? Using a contrib node? Using file backed store set in settings.js?

My settings.js is like this:

I save context variables to file with:

  • 17 change nodes
  • 7 function nodes e.g. flow.set("ct_mon_G", time1, "file");

I load context variables from file to:

  • 17 dashboard nodes with 17 injection nodes
  • 14 function nodes e.g. flow.get("mon_time_G", "file");
  • crontab pro node

And I use one "node-red-contrib-moment" node to show the current time on the dashboard.
I see in the context directory that this node also creates every minute a tmp file

I can't post the flow because of to much characters , but here is a link:

The google home alarm clock flows are made for 2 mobile android phones. When I save a shortcut of this page in google chrome to the mobiles home screen, the dashboard always shows the first tab and automaticaly fills the nodes. But when I switch to the other tab, the nodes are not automatically filled.

So I created a flow, using the ui_control node, which triggeres the nodes again when switching to the other tab.

I figured it out, it was a domoticz mqtt node causing a loop trying to sync the dashboard ON/OFF button with a switch in Domoticz. I used it to turn off the ON/OFF switch with google home voice
