Hello

I ask me a question (Homey pro 2023), I developped small homey script using global variable. It’s works, the variable is correctly updated but I don’t understand why values are not update inside the homey interface ?

Exemple: I use 4 global variables. If I log all values, I can found good values:

But if I display them by homey, variable values stay same as initial values:

Same thing inside the chart:

Did I forget something?

Global variables are not the same as System variables.  
Global variables are created by HomeyScript, System variables you create in f.i. web app-flows editor like the ones you show here above.

example HomeyScript create globalvariable:

```auto
// Create Tags

log('Creating My String...');

await tag('My String', 'abcdef');

```

So what is a difference between

- global.set(‘My String’, ‘abcdef’);

and

- await tag(‘My String’, ‘abcdef’);

Other question, It’s possible to edit System variable from homeyScript ?

Global = for (all) HomeyScript scipts  
Tag = Homey Tags/Tokens to be used in flows.

Yes it is possible to change Logic variables with HomeyScript, there is already some topics about it on the forum ~~somewhere~~.  
Found 1, not the one I first was thinking of, but has the same end results with the correct API points:

I find out the varible’s ID and on “Web API Playground” i wrote the follow instruction: Homey.logic.updateVariable({id: “2de431c4-ddc1-49d8-b98b-536d9acd1d59”, variable: {“value” :48}}) Response “root”:{5 items “\_\_athom\_api\_type”:string"HomeyAPI.ManagerLogic.Variable" “id”:string"2de431c4-ddc1-49d8-b98b-536d9acd1d59" “name”:string"Power\_Surplus" “type”:string"number" “value”:int48} The variable is set . … Instead, Writi…
