Fibaro HC3 to homeLYnk

[tecnorte]

I am trying to make a simple integration between HC3 and LM5.
With Home Center 2 it was working fine but, now since I migrated to Home Center 3, HTTP method just doesn't work as before.
I know I have success on the HTTP communication because it debugs the success response. but I always get the following response as "success message":

[DEBUG] [RESPONSE ]: Unknown parameter "m" (mode)

Here is my code:

Code:

local ip = "192.168.1.100"; -- Logic Machine IP Address
local address = "1/1/2"; -- Group Address to be written on Logic Machine
local http = net.HTTPClient(); -- Http connection request
local zwIdStatus = fibaro.getValue(38, "value") -- Fibaro Device current value
local zwDevStatus = 0 -- Numeric variable for the string concatenation

if zwIdStatus == "true"
then
zwDevStatus = 1
elseif zwIdStatus == "false"
then
zwDevStatus = 0
end

http : request('http://'.. ip ..'/scada-remote?m=json&r=grp&fn=write&alias='..address..'&value='..zwDevStatus,  {
    options = {
        method = "GET",
        checkCertificate = false,
            headers = {
            ['Authorization'] = 'Basic cmVtb3RlOlRlY25vcnRlMjAxNA==',
            Accept = "application/json",
         
            },
        data = ""
    },

    success = function(response) fibaro.debug ("RESPONSE ", response.data)
    fibaro.debug("HEADERS:", response.headers["Content-Type"])
     end,
    error = function(err) fibaro.debug ("Error:" .. err) end
});

fibaro.debug('DEVICE VALUE = ', zwDevStatus)

Can anyone see what's wrong?
