# Matrix Signal bridge for YunoHost [](https://dash.yunohost.org/appci/app/mautrix_signal)   [](https://install-app.yunohost.org/?app=mautrix_signal) *[Lire ce readme en français.](./README_fr.md)* > *This package allows you to install Matrix Signal bridge quickly and simply on a YunoHost server. If you don't have YunoHost, please consult [the guide](https://yunohost.org/#/install) to learn how to install it.* ## Overview A puppeting bridge between Matrix and Signal packaged as a YunoHost service. Messages, notifications (and sometimes media) are bridged between a Signal user and a Matrix user. Currently the Matrix user can NOT invite other Matrix user in a bridged Signal room, so only someone with a Signal account can participate to Signal group conversations. The ["Mautrix-Signal"](https://docs.mau.fi/bridges/python/signal/index.html) bridge consists in a Synapse App Service and relies on postgresql (mysql also possible). Therefore, [Synapse for YunoHost](https://github.com/YunoHost-Apps/synapse_ynh) should be installed beforehand. **Shipped version:** 0.4.0~ynh1 ## Disclaimers / important information ## List of known public services * Ask on one of the following rooms: #mautrix_yunohost:matrix.fdn.fr or #signal:maunium.net ## 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. * If the Bot does bot accept, see the [troubleshooting page](https://docs.mau.fi/bridges/general/troubleshooting.html) * Send ``!sg help`` to the bot in the created room to know how to control the bot. See also [upstream wiki Authentication page](https://docs.mau.fi/bridges/python/signal/authentication.html) #### 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 ``, where ```` 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 `` ### Double puppeting * Log in with ``login-matrix `` * 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](https://github.com/YunoHost-Apps/mautrix_signal_ynh/blob/master/conf/config.yaml), 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. ## Documentation * Official "Mautrix-Signal" documentation: https://docs.mau.fi/bridges/python/signal/index.html * Matrix room (Matrix Bridges in Yunohost): #mautrix_yunohost:matrix.fdn.fr * Matrix room (upstream app): #signal:maunium.net In case you need to upload your logs somewhere, be aware that they contain your contacts' and your phone numbers. Strip them out with ``| sed -r 's/[0-9]{10,}/📞/g' `` * "Mautrix-Signal" bridge is based on the [signal daemon](https://gitlab.com/signald/signald) project. * YunoHost documentation: If more specific documentation is needed, feel free to contribute. ## YunoHost specific features #### Multi-user support * Bot users are not related to Yunohost users. Any Matrix account or Synapse server autorized in the configuration of the bridge can invite/use the bot. * The Signal bot is a local Matrix-Synapse user, but accessible through federation (synapse public or private). * Several Signal and Matrix users can be bridged with one bridge, each user has its own bot administration room. * If several bot users are in a same Signal group, only one Matrix room will be created by the bridge. * See https://github.com/YunoHost-Apps/synapse_ynh#multi-users-support #### Multi-instance support * Multi-instance installation should work. Several bridge instances could be installed for one Matrix-Synapse instance so that one Matrix user can bridge several Signal accounts. * Several bridge instances could be installed for each Matrix-Synapse instance to benefit from it. But one bridge can be used by users from several Matrix-Synapse instances. ## Limitations * It looks like media are not bridged. * Signal chats are not grouped in a Matrix community (as opposed to the Mautrix-WhatsApp or Mautrix-Facebook bridges) ## Documentation and resources * Official user documentation: * Upstream app code repository: * YunoHost documentation for this app: * Report a bug: ## Developer info Please send your pull request to the [testing branch](https://github.com/YunoHost-Apps/mautrix_signal_ynh/tree/testing). To try the testing branch, please proceed like that. ``` bash sudo yunohost app install https://github.com/YunoHost-Apps/mautrix_signal_ynh/tree/testing --debug or sudo yunohost app upgrade mautrix_signal -u https://github.com/YunoHost-Apps/mautrix_signal_ynh/tree/testing --debug ``` **More info regarding app packaging:**
