get value and store in global variable

[dawiinci 5]

I want to get a value from my Arduino Yun. The idea was simple:

The html page look like this: 21.3

This label however is always nil. I tried a lot of variations but it never worked.

Am I missing something?

Btw. Why can't I see these variables when making a new graphic scene?

I used the virtual device since the scenes didn't work well with the html part. Why is this?

Thanks!

Try making it look like a json string, i.e.

{"value":23.1}

And then get the hc2 to parse the json. That should return an array with a single value.

Just make sure that the html has absolutely no other code in it. If you open the source in a browser, it should look exactly like the json.

isnt the syntax

fibaro:getGlobalValue("pc_state") == "active"

?

You are using getglobal without Value.

and did you declare the variable?

eg

--[[

%% autostart

%% properties

%% globals

pc_state

--]]

Be warned Value is with a capital letter hope it helps

You don't need to declare a global in the triggers section. That section will just make the scene trigger if the global variable pc_state changes. You only need to do:

The global variable has already been declared (you did that when you created it in your variables panel).

And if it is a number you want to use as a floating point or integer, the code should look like:

Local is not strictly necessary, but variables should be declared with the correct attributes. "tonumber" parses the global (which is for some reason always returned as a string) into a floating point number so it can be used arithmetically.

I only use getGlobal and it works as expected. Not sure if there is any issues by doing that but I didn't experience any.

Anyway the solution to my task was really simple. No need for JSON in that case as the Arduino passes a straight number.

What is the arduino source code of this project?

 

I am trying to have an input(s) connected on an arduino nano then sent to the fibaro HC2.

 

How to do so?
