This userbot is an autoresponder that responds with a predefined message if no message has been received for a certain time. The timeout time gets calculated for every user.
The timeout is set for each user individually. The userbot only responds to messages from persons. Messages from groups or bots will be ignored.

To use the autoresponder you'll need to create a Telegram Application. Follow this tutorial if you are unfamiliar with that. The following programs are also required:

• docker
• docker-compose

To build the image use sudo docker-compose build

Set all required variables in the file env_autoresponder.

Since telethon generates a session file the first startup, the container must be started initially with sudo docker-compose run autoresponder. After that it stores the session file and the container can be started in the background by executing sudo docker-compose up -d

The message which will be sent is located in ./data/message.py. After editing the message, restart the container with sudo docker-compose restart.

There is an option to exclude users from receiving the automated message. Add a users Telegram ID in the excluded_users array in the file ./data/config.py.

This is an open source project which welcomes any kind of contributions.
