Getting data from Philips Hue Outdoor Motion Sensor

[Odd Egil Aasheim]

Hi.

Just bought this outdoor sensor from Philips, but struggeling to get some data out where it can be used.
I don't want to do something directly inside the Hue system, but to extract data.

The device does not come up in http://<ipadress>/api/<userid>/lights along with my other lamps/led's.
Instead it is visible http://<ipadress>/api/<userid>/sensors

Therefore I tried to modify the user.hue script by adding a section for sensors to search and get data from them.
So far so good.
This is a snippet from the user.hue script where I have duplicated the code, but renamed the original code from i.e function searchHueLights() to function searchHueSensors() and so on.
So "function" 2 and 4 below is new regarding the sensors

Code:

-- function 1 existing huesearch
function searchHueLights()
  local response = {}
  body_searchHueLights= ''
  -- Set username for LogicMachine
  socket.http.request({
  url = "http://"..ip_add.."/api/"..user.."/lights",
  method = 'POST',
        sink = ltn12.sink.table(response),
  headers = {
          ['content-length'] = #body_searchHueLights,
          ['content-type'] = 'application/json',
  },
          source = ltn12.source.string(body_searchHueLights),
  })
  return response
end

-- function 2 new huesearch
function searchHueSensors()
  local response = {}
  body_searchHueSensors= ''
  -- Set username for LogicMachine
  socket.http.request({
  url = "http://"..ip_add.."/api/"..user.."/sensors",
  method = 'POST',
        sink = ltn12.sink.table(response),
  headers = {
          ['content-length'] = #body_searchHueSensors,
          ['content-type'] = 'application/json',
  },
          source = ltn12.source.string(body_searchHueSensors),
  })
  return response
end

-- function 3 existing hue datacollection
function getHueLights()
  local response = {}
  body_searchHueLights= ''
  -- Set username for LogicMachine
  socket.http.request({
  url = "http://"..ip_add.."/api/"..user.."/lights",
  method = 'GET',
        sink = ltn12.sink.table(response),
  headers = {
          ['content-length'] = #body_searchHueLights,
          ['content-type'] = 'application/json',
  },
          source = ltn12.source.string(body_searchHueLights),
  })
  return response
end

-- function 4 new hue datacollection
function getHueSensors()
  local response = {}
  body_searchHueSensors= ''
  -- Set username for LogicMachine
  socket.http.request({
  url = "http://"..ip_add.."/api/"..user.."/sensors",
  method = 'GET',
        sink = ltn12.sink.table(response),
  headers = {
          ['content-length'] = #body_searchHueSensors,
          ['content-type'] = 'application/json',
  },
          source = ltn12.source.string(body_searchHueSensors),
  })
  return response
end

By using this code I then can make a new script for searching

Code:

require('user.hue')
-- get bridge to search for new lights
result = searchHueLights()
log(result)

the log showing that the search is started.

And a new script for reading data

Code:

require('user.hue')
-- get all sensordata from bridge
result = getHueSensors()
log(result)

I get a looooong string, but how can i break it up into the pieces that I want?

 Output from Log window, (it all comes in one long line in the log window starting with * string: {...   ) 

Code:

Let's say that I'm interested in the lightlevel and temperature
I can't find the fomat to extract the data for now.
Any thoughts how to extract?
