Send GET request to https://api.cp.dyson.com/v1/provisioning...e/manifest after the first one to get device list. You need to decode the first result using JSON and then pass Accountassword values as Basic auth. See last example in HTTP docs: http://w3.impa.br/~diego/software/luasocket/http.html

Yes i found why there was no return data. I have to use the v2 api for newer devices:

Code:

https = require 'ssl.https'
require('json')
socket.http.TIMEOUT = 5

local cUsername = 'xxxx@xxxxxx.com'
local cPassword = 'xxxxxxxx'

-- get session info
local cBody1 = '{"Email":"' .. cUsername .. '","Password":"' .. cPassword ..'"}'
local cReq1 = {}
local cUrl1 = 'https://api.cp.dyson.com/v1/userregistration/authenticate?country=NL'
result1 = https.request({
    url = cUrl1,
    method = 'POST',
    headers = {
      ['content-length'] = #cBody1,
      ['content-type'] = 'application/json'
    },
    source = ltn12.source.string(cBody1),
    sink = ltn12.sink.table(cReq1)
})
if result1 and cReq1 then
  cReq1 = table.concat(cReq1)
  cReq1 = json.pdecode(cReq1)
  cAccount = nil
  cPassword = nil
  if cReq1 then
    if cReq1.Account and cReq1.Password then
      cAccount = cReq1.Account
      cPassword = cReq1.Password
    end
  end
  --log(cAccount,cPassword)
else
  log(result1)
end

mime = require("mime")
local cAuth = "Basic " .. mime.b64(cAccount..":"..cPassword)
local cReq2 = {}
local cUrl2 = 'https://api.cp.dyson.com/v2/provisioningservice/manifest'   -- v2 for new devices
result2, c, h = https.request({
  url = cUrl2,
  method = 'GET',
  headers = {
      ['authorization'] = cAuth
  },
  sink = ltn12.sink.table(cReq2)
})
--log(result2,c,h)
log(cReq2)

But the next question, how to decode the password to use it in my mqtt client. Original code from https://github.com/CharlesBlonde/libpure...k/utils.py:

Code:

def decrypt_password(encrypted_password):

    """Decrypt password.



    :param encrypted_password: Encrypted password

    """

    key = b'\x01\x02\x03\x04\x05\x06\x07\x08\t\n\x0b\x0c\r\x0e\x0f\x10' \

          b'\x11\x12\x13\x14\x15\x16\x17\x18\x19\x1a\x1b\x1c\x1d\x1e\x1f '

    init_vector = b'\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00' \

                  b'\x00\x00\x00\x00'

    cipher = AES.new(key, AES.MODE_CBC, init_vector)

    json_password = json.loads(unpad(

        cipher.decrypt(base64.b64decode(encrypted_password)).decode('utf-8')))

    return json_password["apPasswordHash"]
