How to check table data stored in global variable in easy readable JSON format

[Sankotronic 2,205]

Hello everyone!

 

LUA is great with handling data organized in tables. Home automation is all about data. Weather, various measurements, actions can all be nicely stored and organized if data tables are used. Also using tables can greatly reduce number of global variables needed.

 

More about LUA tables and table functions you can find here:

During development of VD's, QA's and scenes and testing it might be necessary to check tables stored in global variables in a nice easy readable format.

 

Here is a way how to do it on HC2:

NOTE: I recommend using Firefox since it has ability to show JSON data

 

1) Go in your Firefox browser to API documentation of your HC: http://<YOUR_HC_IP>/docs/#!/globalVariables/getGVariables_0

It is also possible to copy JSON table and paste it to your LUA editor for further action.

 

Enjoy coding!

You could add Chrome extension jsonvue (or jsonFormatter) and you don't need to copy&paste to another json decoder...

Hi @jgab ,

 

I did what you suggested, but still didn't get nice JSON tree as you can see it on the last screenshot in the right box.

Is there something else needs to be done or this is final result of this extension:

My goal is to get global variable value only that contains table and then get easy readable JSON tree with nice syntax coloring showing string, number and boolean values in different colors. Can JSONVue and Chrome do that?

Ok, I was a bit fast - only used this to look at device structures. Your data is json encoded inside another structure (the global resource structure) so that complicates things.

I may be possible to add som JS to make jsonVue look inside the value...

 

but another approach is to have a QA with one line of code (assume it has deviceId 844) - it becomes a 2-step process.

Then one url to update what variable to look at ex. global variable "A"

and another to look at the actual data (need to be reloaded)

Alternatively, create a dedicated QA that regularly updates a given global variable  (or triggers on that global changing value) - that way you only need to update the first url.
