Hey!

First, I'm sorry if I make mistakes in english...

To do what you want, if I didn't understand wrong (you want to broadcast persons at a specific time, and I guess that time comes from the users preferences) there is a function called "**push**", the bot will send a message without the need of the user to write first. You can **push** a private message to a user or to a group (not sure if this also works in the rooms, I didn't check the docs from some time), the trick here is that you need to save the **user's ID** for example in a database or file, then implement a timer or an event according to the user's preferences and the make "**push**"es to each member with that preference.

Here is a link with the documentation:
