Мы лепили его из того что было но пока не слепили)

https://api.telegram.org/bot{ваш токен}/getUpdates

Делаем уведомление в два действия:

Подставляем имя бота в скрипте на строке :local TelegramBotToken « 123456789:ABCDEFGHIJKLMNOPQRSTUVWXYZ »;

Указываем ID чата или канала в строке :local TelegramChatID «1234567890 »;

# 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 "123456789:ABCDEFGHIJKLMNOPQRSTUVWXYZ";
:local TelegramChatID "1234567890";
: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."
}

Создаем скрипт в разделе system - scripts и не забываем поставить галку Don't Require Permissions

Создаем правило запуска в планировщике.

Указываем: Имя, Дату, Время и интервал запуска скрипта, мне достаточно проверки раз в 20 минут
