NR 1.1.2 From this link New in 0.19 So I believe I am included in this. contextStorage: { default: { module:"localfilesystem", config: { // see below } } } So, off I go to settings.js. contextStorage not found Looking..... // Anything in this hash is globally available to all functions. // It is accessed as context.global. // eg: // functionGlobalContext: { os:require('os') } // can be accessed in a function block as: // context.global.os functionGlobalContext: { // os:require('os'), // octalbonescript:require('octalbonescript'), // jfive:require("johnny-five"), // j5board:require("johnny-five").Board({repl:false}) myDeviceName: "BedPi" }, So we have gone from contextStorage to functionGlobalContext. How do I set it up so context is stored in/on the filesystem? (Just to check:) (now things are getting vague for me) I have seen some nodes talking about context (gate for instance) but then the switch/button node has no mention of this. I want the switch (as in dashboard type) to get their previous state back if the machine is rebooted. Is this the better way of doing it?

[image] Trying_to_learn: Ok, so I may not be actually doing the right thing then. Correct. See node-red/packages/node_modules/node-red/settings.js at master · node-red/node-red · GitHub This is what you need to establish context storage.

How old is the settings.js file? It's easy to keep updating node-RED (which does not update the settings.js file), and then find that new options have been added which require a setting in the settings file. Compare your settings file with the current version - available from github.

(Me showing my stupidity.) Thanks. So next dumb question: How do I make the settings.js file up to date? My efforts at finding the latest settings.js file on github are only showing stuff that are old. Like > 2 years ago.

[image] Trying_to_learn: So next dumb question: How do I make the settings.js file up to date? As I have already said; [image] Paul-Reed: Compare your settings file with the current version - available from github If you just want to add the context storage, just add & edit this, to your settings; // Context Storage // The following property can be used to enable context storage. The config$ // provided here will enable file-based context that flushes to disk every $ // Refer to the documentation for further options: https://nodered.org/docs$ // //contextStorage: { // default: { // module:"localfilesystem" // }, //},

So the part I posted is....... redundant? Superfluous? not needed/used?

[image] Trying_to_learn: So the part I posted is What part?

This: // Anything in this hash is globally available to all functions. // It is accessed as context.global. // eg: // functionGlobalContext: { os:require('os') } // can be accessed in a function block as: // context.global.os functionGlobalContext: { // os:require('os'), // octalbonescript:require('octalbonescript'), // jfive:require("johnny-five"), // j5board:require("johnny-five").Board({repl:false}) myDeviceName: "BedPi" }, Oh, is that more for global context rather than general context? As I said: I'm confused.

[image] Trying_to_learn: So the part I posted is....... redundant? That isn't the section that you need.

Ok, so I may not be actually doing the right thing then. I'm not sure. If I want the switch nodes to go back to the state they were in before an unexpected reboot, is that under this of which I am now asking - or that you showed me - or something else? And other things as well. Reboots can be painful if I am not here/on site. I get that some things will default to things, but a lot of stuff I want to go back to how it was before the reboot.

I hope it works. Obviously I removed the leading // on the required lines and I had to restart NR.

Andrew, maybe this will help too [image] A guide to understanding 'Persistent Context' General It depends on what you have set for the default. Did you read the documentation and the write up I did ?
