Bridging usage

Note that several Signal and Matrix users can be bridged, each Signal account has its own bot administration room. If they are in a same Signal group, only one matrix room will be created.

Bridge a Signal user and a Matrix user

  • First your Matrix user or Synapse Server has to be authorized in the Configuration of the bridge (see below)
  • Then, invite the bot (default @signalbot:yoursynapse.domain) in this new Mautrix-Signal bot administration room.
  • Send !sg help to the bot in the created room to know how to control the bot. See also upstream wiki Authentication page

Linking the Bridge as a secondary device

  • Type !sg link
  • Open Signal App of your primary device
  • Open Settings => Linked Devices => + => Capture the QR code with the camera
  • By defaults, only conversations with very recent messages will be bridged
  • Accept invitations to the bridged chat rooms

Registering the Bridge as a primary device

  • Type !sg register <phone>, where <phone> is your phone number in the international format with no space, e.g. !sg register +33612345678
  • Answer in the bot room with the verification code that you reveived in SMS.
  • Set a profile name with !sg set-profile-name <name>

Double puppeting

  • Log in with login-matrix <access token>
  • After logging in, the default Matrix puppet of your Signal account should leave rooms and your account should join all rooms the puppet was in automatically.

Relaybot: Bridge a group for several Matrix and several Signal users to chat together

  • Create a room on the signal side
  • Your bridged users will be invited on the Matrix side once they are invited on the Signal side
  • You can invite more people over on the Matrix side
  • Have one of the bridged users (who has the right permission) type !sg set-relay on the Matrix side. Their signal account will relay messages from other Matrix users It is not yet possible to bridge to an existing signal room, or create a new signal room from the Matrix side.

Configuration of the bridge

The bridge is roughly configured at installation, e.g. allowed admin and user of the bot. Finer configuration can be done by modifying the following configuration file with SSH: 

/opt/yunohost/mautrix_signal/config.yaml

and then restarting the mautrix_signal service.
