Thanks you.

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:

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:

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

I send the information back, admin please check it for me
I see LM has connected and recognized
Please give me the command to control
Thank you very much

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:

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

end

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