[APP] Better logic / Variable management

Uranday

Make a number variable, create flow that assigns the output of the card to the variable. Use the special assign card that I thought is called set a variable (sry, not behind my pc.  But you can recognise because the dropdowns shows all variables) . This converts the variable (while others enforce the type). Then create a second flow that uses the variable in the condition.

What would be the easiest way to use a Better Logic variable from within another app?

I can get them from a command line at http://homey/api/app/net.i-dev.betterlogic/variable, but how do I do that using JavaScript?

Does Homey.manager allow this? I can get app settings with that just fine

No, that is not possible. The only option is to use the http interface.

MartijnDeRhoter

Do you have an example somewhere of how to do that? The development documentation is a little too cryptic for me (I've had a look at API section, I've created the api.js in the root of the app, but how do I execute the GET?)

MatjaLipu

app 2 app is possible using api. see https://developers.athom.com/library/permissions/

Homey.manager('api').get('/app/net.i-dev.betterlogic/variable', function(err, result) {

  Homey.log(result)

})

MartijnDeRhoter

Thanks! That works! I totally missed the part where it said GET is a method, I used it as a function. Good for when you need errors!

MartijnDeRhoter

Homey.manager('api').get('/app/net.i-dev.betterlogic/variable', function(err, result) {

  Homey.log(result)

})

How would I get the above 'result' in a variable though? Somehow all my attempts end up being null.

I'm missing something here

var test = Homey.manager('api').get('/app/net.i-dev.betterlogic/variable', function(err, result) {

  Homey.log(result)

})

Test ends up being null, whereas result contains what it should. As you can see, I'm not an expert at JS

Uranday

You should assign result to a variable in a higher scope. 

MartijnDeRhoter

Can you give me an example of how to do that?

Uranday

var test;

 Homey.manager('api').get('/app/net.i-dev.betterlogic/variable', function(err, result) {

  test =result;

})

MartijnDeRhoter

var test;

Homey.manager('api').get('/app/net.i-dev.betterlogic/weather', function (err, result) {

   test = result;

})

    Homey.log('Test var contains', test)

If I run that, test still contains null. What gives?

Uranday

But the homey.log before gave an output? 

MartijnDeRhoter

Yes it did! And still does, but as soon as I try and capture that in a variable to use elsewhere, it gets nulled.

If I assign a value to the test variable before, that value gets replaced by null. I'm at a loss here

I can only get output inside the get method, I can't get it out.

Indeed, that works, thanks!

Think synchronous! At the time your code is at Homey.log, the function with result is not yet run.

Try this:

var test

function callback() {

   Homey.log('Test var contains', test)

}

Homey.manager('api').get('/app/net.i-dev.betterlogic/weather', function (err, result) {

   test = result

   callback() 

})

 

MartijnDeRhoter

Ha! I only sort of half know what that means, but the code works!

Thank you thank you thank you - I'll go play with this tomorrow and think synchronous until it makes sense

Submitted version 0.1.0 with the following features:

* Feature: Added API support to GET, GET all variables and SET (post) a value.

    * GET: HTTP://HOMEYADDRES/api/app/net.i-dev.betterlogic/VARIABLENAME

    * GET: HTTP://HOMEYADDRES/api/app/net.i-dev.betterlogic/ALL (Get all variables)

    * PUT: HTTP://HOMEYADDRES/api/app/net.i-dev.betterlogic/VARIABLENAME/VALUE  //Please ensure that the value matches the type, otherwise it will not be set.

Would it be possible to create API support for toggling a boolean where doing a PUT to the URL switches the boolean to it's other value, something like HTTP://HOMEYADDRES/api/app/net.i-dev.betterlogic/VARIABLENAME/toggle . Having that it would for instance allow to create toggle widget buttons in Tasker for Android.

Uranday

I'll put it on my todo list! 

Phuturist

And another thing, would it be possible to add autorization headers with the bearer token to these API requests for better safety (similar as how the Homey api manager works)?

MartijnDeRhoter

If an action card updates a variable using a token, and the token value is the same as the current value of the variable - does the time stamp change on the settings page?

Uranday

I'm not sure. But I dont think so. What I do know is that it does not trigger an event. 

MartijnDeRhoter

It would explain why it looks like some of my action cards didn't run, whereas they did (I use(d) the variable update time stamp as a simple debugging tool).

Uranday

In my mind it only make sense to trigger if it changes. If there is a need for other behavior I can make a card for that.

MartijnDeRhoter

No it's fine, you may want to put it in a FAQ or something - I blamed Erik's HTTP flows because I only looked at the timestamp on your settings page.

And if the flow gets something that doesn't change, it looks like it didn't run.

ErikVanDongen; it's not your app's fault!

Thanks. I just started an investigation

Uranday

Question is, do we want a trigger if the variable is set but not changed?

In HomeSeer I can choose between 'set to' or 'changed to'. And I use them in various scenarios.

Uranday

Thing is, I could add a Variable Set card, but if you have a variable set and variable changed card both will trigger..

Just one question. Did you mean that when you set the variable but it was the same variable as before that still the date changed was changed?

Uranday

For the upcomming release. If anyone has any great sugestions for this release, please let me know!

V0.9.0

* After testing it is very stable, so almost at version 1.

* Removed: Insights is removed for now until Athom stabalized the API for bool, int and string

* Feature: Add toggle to API support

    * PUT: HTTP://HOMEYADDRES/api/app/net.i-dev.betterlogic/VARIABLENAME/toggle This will force to flip the boolean value

* Feature: Enable authorization on the API.   

* Feature: Add 'text starts with' condition

* Bugfix: Dont change last changed timestamp when value is edited manually but not changed.
