Can not get API data from url

[Guest Zooitje]

I have a HomeWizard Energy P1 device connected to my electric meter.

This device has al local api that does not require authentication.

 

There are two api calls:

 

http://<ip-address>/api/v1/data

and

http://<ip-address>/api/v1/telegram

 

http://<ip-address>/api/v1/data gives u the following response:

Please login or register to see this code.

While http://<ip-address>/api/v1/telegram returns the native P1 response.

 

I created a scene wher I want to read the P1 device but with no luck.

My code looks like this:

 

function process(response)
  local http = net.HTTPClient();
  http:request("http://192.168.178.61/api/v1/data",
               { options = {method = "GET"},
                 success = process,
                 error = error });

 

  if (response ~= nil) then
      fibaro:debug(response.data);
 

When I run the scene, nothing happens. The response is nil.

If I change data into telegram, I do get a response with the correct data but it is NOT the data that I want.

 

Can anyone tell me why the response is nil when using: http://<ip-address>/api/v1/data

First question, do you intend to make a scene or quickapp?

[Guest Zooitje]

I have a HC2 so I want to make a scene.

 

I tested it in a VD and that works with the following code (in a VD button).

(port = 80).

 

local self_id = fibaro:getSelfId();
local ip = fibaro:get(self_id, 'IPAddress');
local port = fibaro:get(self_id, 'TCPPort');

 

http = Net.FHttp(ip, port);
response, status, err = http:GET("/api/v1/data");

result = json.decode(response);

 

fibaro:call(self_id, "setProperty", "ui.TellerLabel.value", result.active_power_w);

Oh, you could update your profile, so we know. 
 

maybe you can use this example to make a quick start met a VD:

Thanks.

 

In a VD I have it running but I prefer a scene.

 

When calling the api in a scene the variable "response" remains nil.

I copied the code from another scene that reads the output of my solar panels (SolarEdge) an there it works fine.

 

Could it be that the format of the "data" is wrong?
