What exactly do you want to control via API?

What exactly do you want to control via API?

Thanks for the feedback.

I want to have it detect me and send information via the API to trigger contexts that are specific to me. Or send a welcome home notification to the ceiling speaker.

Run this script as resident. Change host variable to your camera IP and auth variable to access credentials in username:password format. Make sure that Basic auth mode (not digest) is set on your camera. Then post what you get in LM Logs when running this script.

Code:

123456789101112131415161718192021222324252627282930313233343536373839404142434445464748495051525354555657

local json = require('json') local socket = require('socket') local mime = require('mime') local host = '192.168.1.1' local auth = 'user:password' local sock = socket.tcp() sock:settimeout(15) local res, err = sock:connect(host, 80) if not res then   sock:close()   log('connect failed', err)   os.sleep(5)   return end local function init()   local crlf = '\r\n'   sock:send(     'GET /FR/events/live/json?heartbeat=10 HTTP/1.1' .. crlf ..     'Host: ' .. host .. crlf ..     'Authorization: Basic ' .. mime.b64(auth) .. crlf .. crlf   ) end local function parse(resp)   resp = json.pdecode(resp)   log(resp) end init() local pat, len = nil, nil while true do   res, err = sock:receive(pat)   log('rx', pat, res, err)   if err then     sock:close()     log('receive error', err)     break   end   if type(pat) == 'number' then     pcall(parse, res)     pat, len = nil, nil   elseif #res == 0 then     pat = len   elseif not len then     len = res:match('Content%-Length: (%d+)')     len = tonumber(len)   end end

Thanks for the reply.
I am sending the log again as attached file.
Please help me.

You need to trigger a face detection event and check if it's logged. You can disable the log call on line 40 to filter out debug info:

Code:

1

-- log('rx', pat, res, err)

Replace parse function in the script with the following code. The script will send ON to 1/1/1 each time the camera detects you.

Code:

123456789

local function parse(resp)   resp = json.pdecode(resp)     if resp.type == 'person' then     if resp.name == 'luan thanh' then       gpr.write('1/1/1', true)     end   end end

I checked, tested everything works perfectly.
Thank you very much
