Getting data from Philips Hue Outdoor Motion Sensor
#1
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:
Read Hue devices 14.04.2022 17:50:36
* table:
[1]
  * string: {"1":{"state":{"daylight":null,"lastupdated":"none"},"config":{"on":true,"configured":false,"sunriseoffset":30,"sunsetoffset":-30},"name":"Daylight","type":"Daylight","modelid":"PHDL00","manufacturername":"Signify Netherlands B.V.","swversion":"1.0"},"2":{"state":{"presence":false,"lastupdated":"2022-04-14T15:29:10"},"swupdate":{"state":"noupdates","lastinstall":"2022-04-13T18:57:32"},"config":{"on":true,"battery":100,"reachable":true,"alert":"none","sensitivity":2,"sensitivitymax":4,"ledindication":false,"usertest":false,"pending":[]},"name":"OutdoorSensor","type":"ZLLPresence","modelid":"SML004","manufacturername":"Signify Netherlands B.V.","productname":"Hue outdoor motion sensor","swversion":"2.53.6","uniqueid":"00:17:88:01:0b:d1:3a:b5-02-0406","capabilities":{"certified":true,"primary":true}},"3":{"state":{"lightlevel":7186,"dark":true,"daylight":false,"lastupdated":"2022-04-14T15:50:23"},"swupdate":{"state":"noupdates","lastinstall":"2022-04-13T18:57:32"},"config":{"on":true,"battery":100,"reachable":true,"alert":"none","tholddark":16000,"tholdoffset":7000,"ledindication":false,"usertest":false,"pending":[]},"name":"Hue outdoor light sensor 1","type":"ZLLLightLevel","modelid":"SML004","manufacturername":"Signify Netherlands B.V.","productname":"Hue outdoor light sensor","swversion":"2.53.6","uniqueid":"00:17:88:01:0b:d1:3a:b5-02-0400","capabilities":{"certified":true,"primary":false}},"4":{"state":{"temperature":2410,"lastupdated":"2022-04-14T15:48:19"},"swupdate":{"state":"noupdates","lastinstall":"2022-04-13T18:57:32"},"config":{"on":true,"battery":100,"reachable":true,"alert":"none","ledindication":false,"usertest":false,"pending":[]},"name":"Hue outdoor temp. sensor 1","type":"ZLLTemperature","modelid":"SML004","manufacturername":"Signify Netherlands B.V.","productname":"Hue outdoor temp. sensor","swversion":"2.53.6","uniqueid":"00:17:88:01:0b:d1:3a:b5-02-0402","capabilities":{"certified":true,"primary":false}}}

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?

Hi,

funny thing I just started working on the same topic today. :-)

I got it working for the motion state:

1.) Add the following code to the hue user library script:

Code:
-- function get data from sensors
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

2.) Implement a resident script (example for motion):

Code:
addressmapping = {
  -- Name                  -- Presence FB       
  ['Hue motion 1'] = {state = '47/2/6', statevalue = ''},

}


-- Use logging
logging = true

require('user.hue')
require('json')

  reply = getHueSensors()
  mysensors = json.pdecode(reply[1])
  for _, item in pairs(mysensors) do

    -- Check if sensor is found by bridge otherwise it make no sense to send commands
    if item.config.reachable == true then

      -- On/Off
      name = addressmapping[item.name]
      if name then
        addr = addressmapping[item.name]['state']
        if addr and addr ~= '' then
          currentvalue = addressmapping[item.name]['statevalue']
          if currentvalue ~= item.state.presence then
            grp.update(addr, item.state.presence)
            addressmapping[item.name]['statevalue'] = item.state.presence
            if logging == true then
              log('sensor ' .. item.name .. ' state is: ' .. tostring(item.state.presence))
            end
          end
        end
      end 
    end


  end

If you want to have the temperature just looking for the name inside the json e.g. = Hue outdoors temp. sensor 1" and change: "item.state.presence" to "item.state.temperature". This is working I tested it. Due to I just want to have the motion state I didn't implemented it.

To get the json "readable" I used: https://jsonformatter.org/json-parser

I hope this is helping you.

Best Regards
Steffen

In getHueSensors you need to replace return response with return table.concat(response)
Then replace mysensors = json.pdecode(reply[1]) with mysensors = json.pdecode(reply)

Otherwise your script will start failing if the response becomes larger.
