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:

1234567891011121314151617181920212223242526272829303132333435363738394041424344454647484950515253545556575859606162636465666768697071

-- 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:

1234

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:

1234

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:

1234

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:

1234567891011121314151617

-- 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:

123456789101112131415161718192021222324252627282930313233343536373839

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.
