  • Click Groups.

Bots

Our murmur server comes with three broadcast bots: en-bot, es-bot and o-bot

These bots are designed to allow listeners to follow the conversations via a web site. They each broadcast portions of a meeting, via icecast, to https://participate.mayfirst.org/.

For mono-lingual meetings, you only need o-bot (original language bot). Just turn it on and you are done.

If you have a meeting with interpretation, then you will need to use en-bot and es-bot.

en-bot should be dragged into the main room when English is spoken, and into the Interpretation room when Spanish is spoken so that it always broadcast in English. An administrator is responsible for moving this bot during the meeting.

es-bot should be dragged into the main room when Spanish is spoken, and into the Interpretation room when English is spoken so that it always broadcast in Spanish. An administrator is responsible for moving this bot during the meeting.

Administrators can drag and the bots to whatever channel you like. They can be started by sending them the chat message: /start or stopped by sending the chat message: /stop or configured to auto start/stop when the number of people in the room goes above 3 (including the robots).

The bots are installed on toussaint and can be started/stopped/restarted using systemctl (systemctl restart o-bot; systemctl restart o-bot)
