LM and Mikrotik routers - AlexLV - 13.06.2017

Mikrotik network devices more and more popular. I used it more than 2 years.. Know that Mikrotk has API. Can we integrate it with LM?

Possible use - try to swith WiFi On/Off by deep night over LAN from LM, if Mobile device registered at home Wifi - you can start scripts on LM, - Home automatics works you are just comming closer to home... :Smile If somebody try to connect to home Wifi - Mikrotik and LM can try to inform you... API works with no problem with .php, but I don't know LM possibilities..

Have link to some info (russian) :

Hi, AlexLV!
It's time to start russian threads on forumSmile

you could try to send  http request from microtic to LM and then do some logic operations on microtic.
I found some links that might help you (Russian too)
https://toster.ru/q/196163

https://wiki.mikrotik.com/wiki/Manual:Tools/Fetch

in LM you should use remote services

interesting

RE: LM and Mikrotik routers - AlexLV - 16.09.2017

Hello,

just yesterday started to use API from Mikrotik on one other system - now can see my devices connecting and disconnecting to my Wi-Fi, can add action to this, it is working fine. Will try to test more, but want use such functionality with LM...

Is possible implement this Mikrotik API to LM??

May be Guru of LM can adapt API and script and we can use LM with Mikrotik routers?? FOr usage this script I also need enter Mikrotik IP, login and pass. After that my mikrotik showed me list of all connected device's MAC addresses and system wrote - device not recognized. Later I entered for every MAC name of device I want to see and started monitoring of my devices in my WiFI... Can we do such possibilities??

RE: LM and Mikrotik routers - edgars - 09.03.2018

Hi guys,
here is a Scheduled script for Mikrotik RouterOS (v6.41.2) which will monitor WiFi registration table and if one of both MACs appear it will send 1 to grp address 1/1/1 on LogicMachine (192.168.1.13)  via HTTP POST command. If both of MACs disappear from the list, it will send 0 to 1/1/1. 

You can adjust Scheduled script run interval and list of MAC addresses. Or you can send different POST commands for different MAC addresses.

Code:
{
 :local exists [/int wire reg find mac-address="78:02:F8:7A:96:01"];
 :local exists2 [/int wire reg find mac-address="B0:E2:35:CD:46:48"];
 :if ($exists!="" or $exists2!="") do={
    /tool fetch url="http://remote:11111111@192.168.1.13/scada-remote" http-data="m=json&r=grp&fn=write&alias=1/1/1&value=1" http-method=post;
  }  else={
           /tool fetch url="http://remote:11111111@192.168.1.13/scada-remote" http-data="m=json&r=grp&fn=write&alias=1/1/1&value=0" http-method=post;
     }  
}

Here is detailed example.

This script only works if you don't use capsman i think.

RE: LM and Mikrotik routers - gjniewenhuijse - 12.03.2018

i you use mikrotik capsman for wifi management change:
/int wire reg find mac-address=
to
/caps-man reg find mac-address=

RE: LM and Mikrotik routers - DGrandes - 09.11.2019

Hi,

I used this script in my mikrotik to know if a mac was connected to the wifi and works perfectly.


Code:
{
  :local iPhoneDavid [/int wire reg find mac-address="MAC"];
  :local iPhoneVeronica [/int wire reg find mac-address="MAC"];


  :if ($iPhoneDavid!="") do={
     /tool fetch url="http://remote:remote@192.168.2.205/scada-remote" http-data="m=json&r=grp&fn=write&alias=33/1/41&value=1" http-method=post;
   }  else={
            /tool fetch url="http://remote:remote@192.168.2.205/scada-remote" http-data="m=json&r=grp&fn=write&alias=33/1/41&value=0" http-method=post;
      } 
  :if ($iPhoneVeronica!="") do={
     /tool fetch url="http://remote:remote@192.168.2.205/scada-remote" http-data="m=json&r=grp&fn=write&alias=33/1/42&value=1" http-method=post;

      }
}

Is there any way to know witch MAC are connected to DHCP server to use an external Acces Point..

Thanks

RE: LM and Mikrotik routers - edgars - 11.11.2019

Hi! do you want to check on Mikrotik DHCP server lease list either it has specific MAC or not?
If yes, here is the script:

Code:
:local exists [/ip dhcp-server lease find mac-address="78:02:F8:7A:96:01"];

Hi, it works perfectly but it doesn't work for what i whant because dhcp server keep MAC address even if i disconect from the network.
I've seen that ARP lease change DC to C when disconect from network.

Do you know the best option to know conected MAC address to network in real time?

Thanks

RE: LM and Mikrotik routers - edgars - 11.11.2019

I just tried with ARP table. It changes from DC to D if the client is disconnected. In this case you should use the following command:

Code:
:local exists [/ip arp find mac-address="78:02:F8:7A:96:01" and complete=yes];

Ok, i'll tri it!

RE: LM and Mikrotik routers - DGrandes - 30.08.2020

Hi!

I have a question about http post with mikrotik.

I have this code to write value on LM:
Code:
/tool fetch url="http://remote:remote@192.168.2.205/scada-remote" http-data="m=json&r=grp&fn=write&alias=33/1/41&value=1" http-method=post;

But I see that it´s posible getvalue from LM.
I´ve tried this:

Code:
{
  :local value [tool fetch url="http://remote:remote@192.168.2.205/scada-remote" http-data="m=json&r=grp&fn=getvalue&alias=33/1/241" http-method=get];
  :put $value
}


But I cant´t get value. Is there something wrong?

Thanks

The same, i can´t get value

RE: LM and Mikrotik routers - admin - 30.08.2020

I think you're also missing / before tool, it should be:
Code:
:local value [/tool fetch url="http://remote:remote@192.168.2.205/scada-remote" http-data="m=json&r=grp&fn=getvalue&alias=33/1/241" http-method=get];

Yes,

I just see this mistake but it´s not the problem. I try with / (with post and get) and nothing.

See this example and make sure that you have RouterOS v6.43 or newer: https://wiki.mikrotik.com/wiki/Manual:Tools/Fetch#Return_value_to_a_variable

I have routeros v6.44.5.

But I don´t know what´s wrong in my code...

Hi DGrandes,

this works fine on RouterOS 6.43.4 and LM 20200720 (you can paste these commands directly in Mikrotik's Terminal)

Read value:

Code:
/tool fetch url="http://remote:yourPassword111@192.168.1.13/scada-remote" http-data="m=json&r=grp&fn=getvalue&alias=1/0/1" http-content-type="application/json" http-method=post;


You should see something like this in Terminal:

Code:
      status: finished
  downloaded: 0KiBC-z pause]
    duration: 1s

By default output = file and the file scada-remote is created (in Files section). You can see object's 1/0/1 value in this file.

Note! In latest LM version there is IP blocker enabled in case of 5 unsuccessful login attempts. It's related to FTP, SSH, Remote services. The quickest remedy is to reboot your LM5. If this happens, you will see something like this:

Code:
  status: failed

failure: connection timeout


Write value:

Code:
/tool fetch url="http://remote:yourPassword111@192.168.1.13/scada-remote" http-data="m=json&r=grp&fn=write&alias=1/0/1&value=1" http-content-type="application/json" http-method=post;
