Setting up Mautrix Whatsapp (optional)

The playbook can install and configure mautrix-whatsapp for you.

See the project's documentation to learn what it does and why it might be useful to you.

Adjusting the playbook configuration

To enable the bridge, add the following configuration to your inventory/host_vars/matrix.DOMAIN/vars.yml file:

matrix_mautrix_whatsapp_enabled: true

Whatsapp multidevice beta is required, now it is enough if Whatsapp is connected to the Internet every 2 weeks.

The relay bot functionality is off by default. If you would like to enable the relay bot, add the following to your vars.yml file:

matrix_mautrix_whatsapp_bridge_relay_enabled: true

By default, only admins are allowed to set themselves as relay users. To allow anyone on your homeserver to set themselves as relay users add this to your vars.yml file:

matrix_mautrix_whatsapp_bridge_relay_admin_only: false

If you want to activate the relay bot in a room, use !wa set-relay. Use !wa unset-relay to deactivate.

Installing

After configuring the playbook, run the installation command: just install-all or just setup-all

Set up Double Puppeting

If you'd like to use Double Puppeting (hint: you most likely do), you have 2 ways of going about it.

Method 1: automatically, by enabling Appservice Double Puppet or Shared Secret Auth

The bridge will automatically perform Double Puppeting if you enable the Appservice Double Puppet service or the Shared Secret Auth service for this playbook.

Enabling Appservice Double Puppet is the recommended way of setting up Double Puppeting, as it's easier to accomplish, works for all your users automatically, and has less of a chance of breaking in the future.

Enabling double puppeting by enabling the Shared Secret Auth service works at the time of writing, but is deprecated and will stop working in the future.

Method 2: manually, by asking each user to provide a working access token

Note: This method for enabling Double Puppeting can be configured only after you've already set up bridging (see Usage).

When using this method, each user that wishes to enable Double Puppeting needs to follow the following steps:

• retrieve a Matrix access token for yourself. Refer to the documentation on how to do that.

• send the access token to the bot. Example: login-matrix MATRIX_ACCESS_TOKEN_HERE

• make sure you don't log out the Mautrix-Whatsapp device some time in the future, as that would break the Double Puppeting feature

Usage

You then need to start a chat with @whatsappbot:example.com (where example.com is your base domain, not the matrix. domain).
