Twinkly script - gjniewenhuijse - 07.12.2020
I like to connect my Twinkly christmas leds to the LM.
I found a LUA example for Fibaro (see attached Twinkly.LUA), but i can't get the example working.
My code:
Code:
--[[ documentation
api: https://xled-docs.readthedocs.io/en/latest/rest_api.html
mqtt: https://xled-docs.readthedocs.io/en/latest/msqtt_api.html
--]]
-- init
if not init then
require('socket.http')
require('ltn12')
require('json')
socket.http.TIMEOUT = 5
host = "192.168.x.xx"
authToken = nil
init = true
end
local api = {
base = "/xled/v1/",
endpoints = {
login = "login",
verify = "verify",
mode = "led/mode",
deviceName = "device_name",
reset = "led/reset",
movieConfig = "led/movie/config",
movie = "led/movie/full",
gestalt = "gestalt",
brightness = "led/out/brightness"
}
}
function getTwinklyResponseData(endPoint, body, content_type)
local content_type = content_type or "application/json"
local url = "http://" .. host .. api.base .. api.endpoints[endPoint]
local method = "GET"
if body ~= nil then
method = "POST"
if type(body) == "table" and content_type == "application/json" then
body = json.encode(body)
end
end
local response_body = {}
local payload = body
log('input', url, method, payload)
local res, code, response_headers, status = socket.http.request
{
url = url,
method = method,
headers =
{
["Content-Type"] = content_type,
["X-Auth-Token"] = authToken
},
source = ltn12.source.string(payload),
sink = ltn12.sink.table(response_body)
}
log(res, code, response_headers, status)
log('payload', payload)
log('response_body', response_body)
if res and code == 200 then
return true
else
return false
end
end
log('start')
if getTwinklyResponseData("gestalt") then
getTwinklyResponseData("login",{challenge = "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa\a"})
end
log('einde')my data response from "gestalt" looks right with the correct device information, but the "login" gives as result:
Code:
* arg: 1
* number: 1
* arg: 2
* number: 200
* arg: 3
* table:
["server"]
* string: esp-httpd/0.5
["content-type"]
* string: application/json
["connection"]
* string: close
* arg: 4
* string: HTTP/1.1 200 OKCode:
* arg: 1
* string: response_body
* arg: 2
* table:
[1]
* string: {"code":1106}Who can help me?
RE: Twinkly script - admin - 07.12.2020
The challenge = "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa\a" part seems incorrect, try the one from the docs:
{challenge = "AAECAwQFBgcICQoLDA0ODxAREhMUFRYXGBkaGxwdHh8="}
You can also try MQTT instead of HTTP, the integration seems easier for MQTT.

same code 1106 response

Once the application knows the IP address of the lights, it authenticates with them, receives an authentication token and retrieves information about the device.
The authentication process, although a good idea, is flawed. First, the application makes a POST request to the endpoint '/xled/v1/login' with a base64 encoded 32 bit random number. The lights respond with an authentication token, how long it will be valid for, and a base64 encoded response to the challenge. This response is based on the random challenge number, the MAC address of the lights and a shared secret. The phone application sets the authentication token as a HTTP header and sends the received challenge response back to the lights on the endpoint '/xled/v1/verify'. This finalises the authentication allowing for authenticated endpoints to be called.
RE: Twinkly script - admin - 07.12.2020
You are missing the Content-Length header for the POST request. This should help:
Code:
function getTwinklyResponseData(endPoint, body, content_type)
local content_type = content_type or "application/json"
local url = "http://" .. host .. api.base .. api.endpoints[endPoint]
local method = "GET"
local cl
if body ~= nil then
method = "POST"
if type(body) == "table" and content_type == "application/json" then
body = json.encode(body)
end
cl = #body
end
local response_body = {}
local res, code, response_headers, status = socket.http.request({
url = url,
method = method,
headers =
{
["Content-Type"] = content_type,
["Content-Length"] = cl,
["X-Auth-Token"] = authToken
},
source = ltn12.source.string(body),
sink = ltn12.sink.table(response_body)
})
if res then
return code == 200
end
