Description

Now all notifications need to be done using Shoutrrr, but I would like to see the implementation of such functionality in a more understandable way, without additional settings and installations. I really like setting up notifications in Uptime Kuma. To set up Telegram notifications, you need to enter the bot, chat, or thread ID and select a monitor. There is a great lack of such functionality in Beszel. Thanks! :)

All notifications are indeed sent via Shoutrrr, which is integrated into Beszel. There is no need to install anything yourself. You only need to provide the correct URL; the required format can be found here: https://beszel.dev/guide/notifications/telegram. Shoutrrr takes care of the rest.

We integrated Shoutrrr to support as many notification channels as possible without having to maintain each one separately, as we do not have the time or capacity to do so. As a result, there are currently no plans to add separate notification channel implementations outside of Shoutrrr.

It's a pity, in that case, could you give me instructions on how to connect Telegram? I didn't find it in the documentation.

Our docs are here: https://beszel.dev/guide/notifications/telegram

The upstream Shoutrrr docs are here (note that we replace the title param, so don't use it): https://shoutrrr.nickfedor.com/v0.13.1/services/chat/telegram/

This issue might be helpful: #1101.

I don't use Telegram myself, and it seems to be more confusing to set up than other notification services, but others have confirmed that it is working correctly.
