Mikrotik Scripts: sending power on notification to Telegram

MikroTik script sends a power on notification the device to Telegram. Allows you to learn about unexpected device reboots or equipment power problems, complementing the monitoring system.
When sending a message to Telegram, it will also write the event to the system log.

🔔 For the script to work, you must have a Telegram bot Token and a chat ID or a personal ID. Creating a Telegram bot and getting the required IDs is not the topic of this article.

The Telegram message contains:

  1. device identifier;
  2. information message about device startup.

Change device Identity

Change the device ID to better understand which device is sending the request.

[System] -> [Identity]

or

/system identity set name="WhiteHouseMikroTik"

Create a script notification about device power on

The script creates the RebootStatus variable.
If the RebootStatus variable does not matter (which happens when the script is launched for the first time), a message is sent to Telegram.
Then the RebootStatus variable is set to True.

For the script to work, you must set the following permissions: read, write, policy, check.

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

Script code:

# Func: Telegram send message
:local TGSendMessage do={
    :local tgUrl "https://api.telegram.org/bot$Token/sendMessage?chat_id=$ChatID&text=$Text&parse_mode=html";
    /tool fetch http-method=get url=$tgUrl keep-result=no;
}

# Constants
:global RebootStatus;
:local TelegramBotToken "987654321:AAFJIVTAWodBwzGX2CLne6-PK4RFNSy-8OY";
:local TelegramChatID "987654321";
:local DeviceName [/system identity get name];

:local TelegramMessageText "\F0\9F\9F\A2 <b>$DeviceName:</b> start after Power Off.";

# Program
:if ($RebootStatus != true)  do={
    $TGSendMessage Token=$TelegramBotToken ChatID=$TelegramChatID Text=$TelegramMessageText;
    :set RebootStatus true;
    :log info "Script CheckPowerOn send Telegram message."
}

Add script launch to schedule

For the script to work, you must set the following permissions: read, write, policy, test.

[System] -> [Schedule] -> [+] -> [Name: CheckPowerOn script] - > [Interval: 00:05:00] -> [Policy: read, write, policy, test]

Script code:

/system script run CheckPowerOn
Adding a script for checking device startup and sending a Telegram message to the MikroTik task scheduler

Now every 5 minutes the device will check the reboot variable and send a notification to Telegram if the device has been rebooted.
