Druvis from Mikrotik produced a video "MikroTik Telegram bot - Chat with
your Router?". He shows his script to chat with a Router via Telegram
bot to send it commands: https://youtu.be/KLX6j3sLRIE
This script is kind of limited and has several issues... 🥴
Let's make it robust, usable, multi-device capable and just fun! 😁
(Sadly Mikrotik has a policy to not allow links in Youtube comments.
Thus my comment with several hints was removed immediately. If anybody
is in contact with Druvis... Please tell him about this script!)

New RouterOS releases bring new features, and thus new syntax.
Installing a new script on old RouterOS results in syntax errors. We
want to give clear warning messages, so by adding an extra comment into
the script...
# requires RouterOS, version=7.8beta3
... installing on unsupported RouterOS version is mitigated.
To filter in firewall you should use something like this:
/ip/firewall/filter/add action=reject chain=output out-interface-list=WAN port=514 protocol=udp reject-with=icmp-admin-prohibited;
/ip/firewall/filter/add action=reject chain=forward out-interface-list=WAN port=514 protocol=udp reject-with=icmp-admin-prohibited;
Flushing the mail queue with resolver issues can flood the log with
messages like:
e-mail;error Error sending e-mail <=?utf-8?Q?[MikroTik] =F0=9F=92=BE=E2=98=81 Cloud backup?=>: DNS resolve failed
Try to avoid this...
The functions do not rely on perfectly synced time. About the right time
is fine, that should make sure certificates are valid and mails are sent
with reasonable headers. So cache the result if system is fine for later
use.
In RouterOS 7.x the ntp client and server are bundled and unique and
can not be unavailable.
Also it does no longer have a 'last-adjustment' property...
