MikroTik Scripts: Device overheating notification

Notification when the device temperature rises above the threshold. Sends notification to email or Telegram message.

The script sends the temperature of the MikroTik device and the CPU load. If the temperature of the device has exceeded the threshold value, and the processor load of the device is minimal, there may be a problem in the external environment (for example, the failure of an air conditioner in a server room).

Functions used:

MikroTik script is suitable for devices equipped with a temperature sensor. Tested on Mikrotik RB3011UiAS-RM, RouterOS 6.46.4 (stable).

The safe value of the CPU temperature will be different for each model of MikroTik devices, set the value of the script trigger temperature (MaxCPUTemp) depending on the model of your device (see the specification).

Create script

The MaxCPUTemp parameter is the device temperature threshold after which a notification will be sent.

For the script to work, checking the device temperature requires permissions: read, write, test, policy.

[System] -> [Scripts] -> [+] -> [Name: DeviceOverheatingScript] -> [Policy: read, write, test, policy]

Script code:

# Name: DeviceOverheatingNotification v1
# Description: Notification when the device temperature rises above the threshold. Sends notification to email or Telegram message.

:local CurrentCPULoad [/system resource get cpu-load];
:local DeviceName [/system identity get name ];

MikroTik script device overheating notification

Add script to Scheduler

To run the script to check the temperature of the MikroTik device, permissions are required: read, write, test, policy.

[System] -> [Schedule] -> [+] -> [Name:CheckDeviceOverheating] —>  [Interval: 00:01:00] -> [Policy: read, write, policy, test]

Or enter in a terminal:

/system scheduler add name=CheckDeviceOverheating policy=read,write,policy,test on-event="/system script run DeviceOverheatingScript" interval=1m comment="Checking device overheating"
Add script to check device overheating to the schedule

Now you can increase control over your device by monitoring an important parameter – device temperature!

? How to create a script to check the overheating of a MikroTik device and send a notification to an email or Telegram message has been discussed in this article. I hope now you can get notification about MikroTik device overheating and CPU load on time. However, if you run into any problems while configuring the script, feel free to write in the comments. I will try to help.

    • My hardware Model: Metal G-52SHPacn.

      : local CurrentTemp [ /system health get [ find name=temperature ] value ]; # By example : 31
      : log warning “$CurrentTemp °C “; # ==> 31 °C

      Same structure the Voltage
      : local CurrentVoltage [ /system health get [ find name=voltage ] value ]; # By example : 23.8
      : log warning “$CurrentVoltage VDC “; # ==> 23.8 VDC



  1. Replace the original line :
    :local CurrentTemp [/system health get temperature];
    by the following hereafter:
    : local CurrentTemp [ /system health get [find name=temperature] value ];


  2. Próbowałem :local CurrentTemp [/system health get [find where name=”cpu-temperature”] value=value]; ale nie działa :/

  3. Welcome back
    You could do a script update ?

    System temperature [/system health get temperature]
    Cpu temperature [/system health get cpu-temperature]

    In my case, the processor temperature is given.
    Can I count on help and script improvement?
    Best regards, Tomek from Poland

  4. Hello

    This scrypt doesn’t work for me.
    My device is RB5009 with ver 7.1.1
    I corrected one parameter:: local CurrentTemp [/ system health get temperature]; na: local CurrentTemp [/ system health get cpu-temperature];

    but unfortunately it still doesn’t work. The ParseLogLoginFailure and ParseLogAccountEvents scripts work fine.
