Matrix

Matrix is a decentralized, open and encrypted chat platform that allows for group chats and private messages while being able to be self-hosted on an own server. Matrix also allows to connect it with other messengers, so it is possible to chat with Signal, Telegram, Whatsapp etc users inside Matrix, although this requires advanced technical knowledge to set up. With all these features, Matrix has the potential to become a messenger standard that replaces the current messenger chaos, similar to how e-mail is the standard for longer letters.

The Ecotopia Biketour has some Matrix groups that are “bridged” with Signal. This means that each group exists both on Matrix and on Signal, and messages are copied between the two groups by a bot. This way people who have a Matrix account can join the Matrix group (without having to reveal their phone number), while people who only have Signal can join the Signal group, but both can talk to each other.

Set up a Matrix/Signal group

1. Set up the Signal group first. Invite the Matrix bot (+4915129124299) to it.
2. Log in on https://matrix.ecotopiabiketour.net/ as the user bot. This user has the single purpose to administrate the Matrix/Signal connection. You can find the password and security key for the user on the Cloud.
3. A Matrix room has been automatically created for the Signal group and you should see an invitation to it. Accept that invitation.
4. In the Matrix room, send the message !signal set-relay. This will enable the bot to copy the messages between the two groups.
5. In the Matrix room, send the message !signal set-pl 100. This will make the bot user an administrator of the group. This will allow you to adjust the group settings.
6. Enter the Ecotopia Biketour space on the left, click + and then “Add existing room”. There, add the Matrix room.
7. Enter the room settings of the Matrix room, click on “Security” and for “Access” select “Space members”.
