Python Plugin: MAC address presence

[Xorfor]

Great these Python plugins!!! Will the Domoticz team move all currently supported devices to python plugins?

I created a plugin to detect whether a mobile phone is in the Domoticz network, identified by MAC address. So, no fixed ip addresses are required. Still some work to do.

Please look at: https://github.com/Xorfor/Domoticz/tree ... acpresence

[Logread]

I wrote a similar plugin - with wake-on-lan and remote shutdown options - some time ago but did not yet find time to polish it for a public release, however I noted that a simple « arp-scan » did not reliably detect some mobile devices.

I had to force a repeat option for the scan and also move the scanning process to a shell script called by a cron, in order to avoid locking the python thread during a scan.

What is your experience with reliability of detection for mobile devices ?

[Xorfor]

@Logread: You are right, the reliability of detection of devices is not very good. That is one of the reasons that I added a timeout of 10 minutes (by default). An other reason for the timeout is that you will not switch off the heating immediately because you leave your home for a minute.
Arp-scan and also arp on windows need some retries to find the devices.
I use a lua script (like this python version) for months and that is working very good.

Hi Xorfor,

I'm really interested in this solution, so I installed your plugin and get NO errors
But the device status is not updated either
Running v3.8153 on a RPI
Triple checked the MAC adress, phone is pingable.

Did you install arp-scan???

I forgot to mention it in the readme. I just did an update.

The installation can be done (on Raspberry Pi) by:

sudo arpt-get arp-scan -y

Hope this helps. Be aware that arp-scan is not a bullet proof solution to scan mac addresses. But with a timeout of 10 minutes, I didn't have any problem with 3 mac addresses.

[Rodio]

Hi,

installed arp-scan now
Rebooted several time, because of error MacDetect ended abruptly (i think)
after 3rd reboot the errors disappeared .
Now I get this messages, but both phones are active at this moment (AccesPoints (apple airport) see them both.

[Xorfor]

@Rodio

Did you try on console: sudo arp-scan -lq? This is actual what the plugin is executing. Sometimes it will take a while before a device gets listed.

[EdwinK]

Could this (and your other script) also be used stand-alone. I (and others) seem to have problems running plugins from the RPI.

[Xorfor]

@EdwinK: This is the 'old' LUA code I used:

Code: Select all

-- List of smartphones with the mac address
local smartphones={} 
smartphones['Name1']='xx:xx:xx:xx:xx:xx'
smartphones['Name2']='xx:xx:xx:xx:xx:xx'
smartphones['Name3']='xx:xx:xx:xx:xx:xx'

function timedifference(s)
  year = string.sub(s, 1, 4)
  month = string.sub(s, 6, 7)
  day = string.sub(s, 9, 10)
  hour = string.sub(s, 12, 13)
  minutes = string.sub(s, 15, 16)
  seconds = string.sub(s, 18, 19)
  t1 = os.time()
  t2 = os.time{year=year, month=month, day=day, hour=hour, min=minutes, sec=seconds}
  difference = os.difftime (t1, t2)
  return difference
end

commandArray = {}
-- save list of connected devices
os.execute("sudo arp-scan -l -q > /tmp/scan-arp.txt") 

for key, mac in pairs(smartphones) do
  -- search for the mac address in the temporary file
  local mac_success=os.execute("sudo grep -e " .. mac .. " /tmp/scan-arp.txt") 

  if mac_success then
    -- device available, or wait 5 minutes
    if ( 
        otherdevices[key] ~= 'On' 
        or timedifference(otherdevices_lastupdate[key]) > 300 
       ) 
    then
      print("MAC address: " .. key .. " (" .. mac .. ") in LAN")
      commandArray[key] = 'On'
    end
  else
    -- device not detected after 10 minutes, then switch off
    if ( 
        (otherdevices[key] ~= 'Off' and timedifference(otherdevices_lastupdate[key]) > 600) 
        or timedifference(otherdevices_lastupdate[key]) > 1800 
       ) 
    then
      print("MAC address: " .. key .. " (" .. mac .. ") not in LAN")
      commandArray[key] = 'Off'
    end
  end
end

return commandArray

Create a dummy device (this is not working with 3.8775, so wait for a fix for that) with a switch for each mac address (mobile phone). Create in Events a new LUA/Time event with above code. Replace Name1 ... Name3 (or more) with the names of the just created switches and fill in the corresponding mac addresses.

[EdwinK]

Thanks. Looking into this one

[Rodio]

Hi Xorfor,

I got an answer, including the MACs of the 2 phones, but still Domoticz doesn't seem to know.
What I noticed is that the arp-scan returns lower-caps, so I changed one of the devices in lowercaps.
Did not help


Thx
R

[Xorfor]

@Rodio: I made some improvements and added extra debugging. Can you please try the latest version.

[Rodio]

ehhhhh



sooooooooo heeeeeee

stupid me, the lowercase was the solution.
But I didn't notice the extra space I put behind the devicename.
I entered 'S6, xx:xx:xx:xx' instead of S6,xx:xx:xx:xx.

So now both devices work

so my solution is 'S6,12:a3:bc:d4:56:ef'

I'm happy and gonna test some more.

@Xorfor, thx for the help.
I really appreciate it

[Rodio]

I disabled the WiFi of the S6, just to test.

Hi Xorfor, do you think it's possible to have a version without arp-scan? That would make it usable in more situations.

I'm no programmer of any sorts but I tried this in a shell:

Code: Select all

#flush cache to get rid of old stuff
sudo ip -s -s neigh flush all
#look for the mac on the network
arp -a | grep -v incomplete | grep -i "xx:xx:xx:xx:xx:xx" > phone

This gives me a file named 'phone' with mac and IP address on one line. So no need for arp-scan
Is this something you could use in your script as an alternative?

[Bolten88]

Is this plugin still working?
