Using API with Arduino

[gilbert 0]

Hope somebody can help me...

I want to use my Arduino Uno for sending a http request to HC2 for turning off a light. When I enter

"http://admin:[email protected]:80/api/callAction?deviceID=7&name=turnOff"

into the address bar of my browser, the light nicely turns off.

I tried the following code for the Arduino, but with no succes:

I tried different things like PUT and POST and different examples I found on different forums. The serial monitor of the Arduino IDE prints "connected", so I assume a connection is established with the HC2. I'm not that familiar with http requests so any help is appreciated

gilbert, try with on the same line

. Perhaps try encode url

but I don't know much about this platform... Good luck

The reason your browser is successfull is because you are logged in to the HC2 with a session. But you don't enter your credentials with your arduino code...

So you have to find out how to add that. I am very interested in the code you are building. Was thinking of building a Arduino device with a Keypad, rfid, and tts engine for arming and disarming the alarm with voice feedback. What kind of arduino and module do you use?

Krikroff, thanks for your reply. I will try this tonight.

stevenvd, I hoped using

would log into the HC2. But 'm not sure it works correctly.

I use an Arduine Uno Rev3 with an ethernet shield (Wiznet W5100) from dealextreme.

You can also try

or put basic authentification (encoded in Base64) in header:

Krikroff Thanks for your help, appreciate it. I tried a lot of things, but with no succes. I think indeed the problem is with the authorization.

As I did not found examples for http communication between Arduino and HC2, I found enough examples of http communication between Arduino and Vera from micasaverde. I assume it also needs authorization, but I don't know the Vera.

Nevertheless, I made some progress. I managed to create a TCP connection between HC2 and Arduino. To do this I created a virtual device button with the following code:

The Arduino can read this code and send back an acknowledgement using the following code:

However, to get information from Arduino, HC2 has to poll the Arduino, for example each x seconds in the main loop of the virtual device. I know this isn't the best solution, but for me it will work for the things I want to achieve.

Still, any suggestions and tips are welcome

gilbert, have you try to add a custom header to your http request with

? normally it should work...

Solved the problem?

Did you manage to get it working? I want to build a wall thermostat and Alarm panel on an Arduino with a 4d systems touchscreen and Wifi shield.

Is it possible to tunnel through with API commands on Fibaro remote service?

 doubt that you can.

[Guest samuelboerhoop]

gilbert or others how did you solve the problem?

 

I have a arduino nano with en enc28j60 ethernet module. 

a webserver, with a webpage is working, with 4 inputs and 4 outputs, displaying.

From my HC2 I can sent commands to the arduino nano to switch on/off the relays, when i go to the webserver from the arduino nano on the webpage i am able to switch on/off the relays too.

 

Now I have to arrange the inputs feedback and output feedback towards the fibaro hc2 isn't working yet.

 

if someone needs my arduino sketch let me know. 

 

when i type this line below in a normal browser it will trigger by means of a VD button a global variable.

So i need to convert this to arduino language to sent to the fibaro hc2

login = loginname from hc2

password = password from hc2

ip-address-hc2 = ip address from Hc2

deviceid = device id from virtual device

last digit 1 = number button

 

love to hear from you guys

Gilbert: you said: However, to get information from Arduino, HC2 has to poll the Arduino, for example each x seconds in the main loop of the virtual device.

 

What is the code you put in de main loop to read the response ? Thanks for sharing
