    using curl and particle functions

    well, i figured out how to replace the webclient which no longer works with curl, and have posted what i did to help others.

    first, i have a particle device that accepts a function called led. it has 4 arguments: led, red, green, blue. these get passed to the particle function as a string like this: led,red,green, blue

    i used
    • putty to get into homeseer
    • winSCP to transfer files back and forth
    • dos2unix to remove all the hidden windows formatting since i wrote on my PC

    i created script called and placed in into /usr/local/HomeSeer/scripts.


    echo $PARAM

    curl[id]/led -d arg=$PARAM --data-urlencode access_token=[token]

    i added that directory to the path
    export PATH=$PATH:/usr/local/HomeSeer/scripts)

    i made sure the script was executable:
    chmod +x

    i checked that it works by typing on the command line
    ./ 10 255 128 64

    now create an event in Homeseer and select RUN ANOTHER PROGRAM OR PROCESS not (RUN A SCRIPT), select your script and add you params under the advanced tab. params here should be seperated by spaces, not commas.

    and you are done!

    No longer working

    This worked for quite sometime, but during the last update on Homeseer for me it stopped.

    when i run the script i now get

    Exception: Error getting response stream (Write: The authentication or decryption has failed.): SendFailure

    and i really dont know enough to know why.

    If i run my command via curl on my pc everything works so i know my token/device_id/events etc are all ok.

    any ideas on what to check?

    also, does anyone have an example calling curl from a vb script? i could do that just as easy as webclient

    Perfect. I ended up with this code:

    Const LT As String = "Particle"
    Const DeviceID As String = "deviceID"
    Const AccessToken As String = "AccessToken"

    Sub Main(Parm As Object)

    Dim URL As String = "" & DeviceID & "/led" 'led is the name of our access point
    Dim responsebytes() As Byte
    Dim commandToSend As String = "9,255,255,0"

    Using Wclient As New Net.WebClient
    Dim headerlist As New Specialized.NameValueCollection
    headerlist.Add("access_token", AccessToken) 'Send the access token
    headerlist.Add("params", commandToSend) 'to match the entry command in the spark code
    responsebytes = Wclient.UploadValues(URL, "POST", headerlist)
    hs.writelog(LT, "Reply: " & System.Text.Encoding.ASCII.GetString(responsebytes))
    End Using

    Catch ex As Exception : hs.writelog(LT, "Exception: " & ex.Message.ToString)
    End Try
    End Sub

    and I get this in the log:
    May-30 12:26:42 PM Particle Reply: {"id":"devideID","last_app":"","connected":true,"return_valu e":1}

    Sending HTTPS commands to Particle Photon

    hi all,

    converting from a vera to HS3 finally, and wanted to get peoples advice on the best way to send commands to my particle photon. Basically I need to send SSL commands to send and get data.

    Lets start with the easy one, the code below would send a message to my photon. in vera i would do this via Luup:
    local socket = require('socket')
    local https = require('ssl.https')
    local ltn12 = require('ltn12')

    https.TIMEOUT = 5

    local body, code, headers, status = https.request("{device}/led","arg=9,255,255,0&access_token={token})

    return true

    very simple, it would basically POST via SSL to my photon.

    What would be the best way to do something like this via scripting in HS3?
