Control Arduino with HC2

Question

Hi there,

 

I'm building a Nextion touchscreen with a arduino ESP8266 chip. I already can start scene's from the display. I'm now struggeling with a way to communicate back. Is there someone who can tell me how to send value's from a variable in Fibaro HC2 to the arduino ESPchip?

 

I created a webserver running on the arduino and can make different actions on it i.e. /ledon runs a led on script on the arduino. But this way i need to make a different script for every single action/value of a variable. undoable when I want to send temp or lux to the arduino. Is there a way, so yes how, to send the value of a global variable in fibaro HC2 to a global variable in the arduino.

 

Cheers,

 

Damien

Or you can build on the Z-Uno, an Arduino board with a Z-wave chip. Very easy to use.

    I'm familiar with the docs page, thanks.  Do I have to think the other way around? Let the arduino make GET commands in order to 'fill' it's variables?

            success = function (response)
                if response then
                    opt.success(response)
            end,
            error = function (error)
                opt.error(error); 
            end    
        })
    end

     

    function setLedOn()
        asyncGet(
            'http://' .. ip .. '/ledon', 
            {
            success=function(resp)
                local data = json.decode(resp.data)
                if data.code == 1000 then
                else
                end            
            end, 
            error=function(error)
            end
            }
        )
    end
     

    Is this what you mean?
