Is there any way that I can get DHCP table?

You should save the device IP in storage and periodically run the scan via a scheduled scripts to check for IP changes. You should also set a lower value for socket.http.TIMEOUT because default is 60 seconds to speed up the script. Check if your device has a non-standard TCP port open so the scan more consistent, because many network devices can have port 80 open.

Here's a script that can quickly check if any of local IPs have port 80 open:

Code:

1234567891011121314151617181920212223242526272829303132333435363738

require('socket') prefix = '192.168.1.' -- ip address prefix rangemin, rangemax = 2, 254 -- min/max of the scan range port = 80 -- TCP port to check sockets = {} ips = {} -- create sockets and connect for i = rangemin, rangemax do   ip = prefix .. i     sock = socket.tcp()   sock:settimeout(0)   sock:connect(ip, port)   sockets[ #sockets + 1 ] = sock   ips[ sock ] = ip end -- get a list of sockets that can be written to, this means that the connection is established _, res, err = socket.select(nil, sockets, 1) res = res or {} -- log IPs of all sockets that accepted the connection for _, sock in ipairs(sockets) do   if res[ sock ] then     ip = ips[ sock ]     log(ip)   end   sock:close() end -- clean-up in case running as a resident script sockets = nil ips = nil

Is it possible to get Name and MAC adress with this script?
