Get a Telegram message when an AP, OLT, server or the ISP link goes down and comes back.

Create a bot with @BotFather to get its token, add the bot to your technicians' group, then get the group's chat ID (it starts with a minus). The router sends a message with /tool fetch every time a host changes state. On RouterOS v6 netwatch only has a simple ping check.

• The router must resolve DNS and reach the internet (api.telegram.org) to send the messages.
• Test it: switch one host off for a moment, the DOWN message should arrive in the group.

How to use: Copy the script, open Winbox → New Terminal, paste. Or Download .rsc, upload it in Files, then run /import file-name=netwatch-telegram.rsc.
