Admin Bot

Matrix brings lots of possibilities for collaboration through federation of different homeservers. This calls for moderation tools which consider the decentral power levels of Matrix rooms.

Admin Bot is only available on homeservers with the Element Enterprise Cloud plan.

Admin Bot is a service account which works in addition to the EMS Server Admin UI and Synapse Admin API.

Most administrative tasks in a Matrix room require a local account with the power level "Administrator" (100) to be a room member.

The Admin Bot extension ensures this by inviting and promoting the account adminbot in every Matrix room created on your server. This way you can moderate content in these rooms, invite and promote room members and kick or ban unwanted members.

AdminBot for global room administration.

Setup

  1. Go to the Integrations tab on the EMS homeserver page.
  2. If you have more than one homesever, select the homeserver to add Admin Bot to.
  3. In the section Extensions, click on Admin Bot. If this is not visible, check that the homeserver is using the Element Enterprise Cloud plan.
  4. Click on Set Up Integration and confirm the pricing in a modal.

Usage

Admin Bot improves your ability to use the Server Admin tab on the EMS homeserver page and Synapse Admin API by having a local admin in every room.

Furthermore, you can use Element Web to log into the adminbot account:

  1. Go to the Integrations tab on the EMS homeserver page.

  2. If you have more than one homeserver, select the one you want to administrate.

  3. In the section Extensions, click on Admin Bot. If this is not visible, check that the homeserver is using the Element Enterprise Cloud plan.

  4. If this is the first time you log in using this browser, click Secure Backup Phrase (click to view) and copy the phrase to your clipboard.

  5. Click on Log in as Admin bot. You will need to enter the Secure Backup Phrase on first login with a new browser in order to access Secure Storage and encrypted messages.

Removal

Removing the integration will not cause the user adminbot to leave rooms. This is a separate step to make mistakes easier to recover from. If the integration was accidentally deactivated and Admin Bot left rooms as the last local Administrator in that room, such rooms can no longer be moderated by anyone and need to be abandoned. Those room also couldn't be rejoined by Admin Bot.

You can deactivate the adminbot account using the EMS Admin GUI or Synapse Admin API, if you want it to leave all rooms.

Audit Bot

Audit Bot is for compliance with the law or your organization's guidelines. This service account allows you to read every conversation on your server, including encrypted conversations.

Audit Bot is only available on homeservers with the Element Enterprise Cloud plan.

  15. Add the Element Bridge

  16. The Matrix room and Slack channel are now bridged

Signal Bridge

This guide explains how to use the Signal bridge from the EMS Integration Manager to integrate your Signal chats with your EMS server.

It requires your EMS server to have federation on.

The following instructions are done with the Element Desktop on the Element side and on Element iOS for the Signal side. Element Android should be almost identical to Element Web.

Purchase the Signal integration

  1. Open the EMS control panel at: https://ems.element.io/user/hosting
    Click the Integrations tab and if you have more than one server, select the server you wish to add the Signal integration to.

  2. Click on Signal Bridge in the list of available Bridges.

  3. Enter the maximum number of users in Maximum Signal users.
    Please note: this is the maximum number of Signal users who actually send messages over the bridge each month. You are only billed for the number of Signal users who are active. Once you exceed the maximum, then the bridge will be disabled until you increase the maximum.
    If you enter less than 5, you will get a warning.

    If you enter 5 or greater in Maximum Signal users, you will not see a warning.

    Once you have entered Maximum Signal users, click Purchase (remember you can always go back to this step and increase the maximum number of Signal users if you need more in the future).

  4. A dialogue will remind you of the price per user and ask if you wish to proceed. Click Purchase if you wish to proceed with the Signal Integration.

  5. You will have to wait a few minutes while your host is reprovisioned with the Signal bridge. Once reprovisioning is finished, you are able to bridge Signal to your EMS server using your Element client.

Bridge Signal to your Element account

  1. Once the bridge is running, open your Element app. Click on the + next to People.

  2. Create a Direct Message conversation by typing @signalbot:example.ems.host (replace the domain with the one of your homeserver). Then click Go.
    element-dm.png

  3. The bridge account will join your room and tell you how to use it.

  4. Open Signal on your mobile device (iOS or Android) and tap on your avatar to go to Settings and then Linked Devices and then + to start the Signal QR code scanner. You will use this QR code scanner to scan a QR code displayed by your Element client in the next step.

  5. From your Element client, send a login message to the bot to connect to your Signal account.

  6. A QR code will be displayed. Quickly scan the QR code with Signal on your mobile device. You have about a minute before it times out. If it times out, just send the login message again to generate another QR code.

  7. On your Element client, you will see Successfully logged in as <your_phone_number> (UUID: <your_signal_id>). Once a new message arrives in one of your Signal chats, you will see an invitation for it in your Element client. Each Signal chat is a separate Matrix room. Join one or more chats and start chatting from either your Element app on desktop, iOS or Android or your Signal on mobile.

Sending a message to a Signal User

To send a message to a Signal user, you must first be connected to the bridge (see above). This currently works only for Signal users that the bridge has seen activity from.

  1. On your Element client, open your DM with the Signal bridge bot.
  2. Say pm followed by the phone number for your contact.
  3. You will be invited to a DM with that user, and can send messages to them.

Why do Signal user names show up as phone numbers?

Some signal users may appear as a phone number rather than their real name. This can because of one of the following reasons:

  1. The user has not spoken to you on Signal yet, and so has not sent their profile information.
  2. The user has not added you as a contact on their phone.
  3. The Signal bridge has not yet synchronized the profile information of the user from Signal (this should happen fairly soon after your first interaction).

EMS does not support the bridge as a primary device

The EMS Signal Bridge is implemented as a secondary device bridge in order to prevent Signal from ratelimiting the bridge. This means that you still need Signal installed on your iOS or Android device in order to use the bridge.

Slack Bridge

The Slack bridge is no longer available for purchase. This documentation is for existing customers of the bridge only.

The EMS Slack bridge is a paid integration for EMS homeservers. In addition to the features provided by the matrix.org bridge, it:

Purchase the Slack integration

  1. Open the EMS control panel at: https://ems.element.io/user/hosting

  2. Click the Integrations tab and if you have more than one server, select the server you wish to add the Slack integration to

  3. Click on Slack Bridge in the list of available Bridges

  4. Enter the maximum number of users in Maximum Slack users.
    Please note: this is the maximum number of Slack users who actually send messages over the bridge each month. You are only billed for the number of Slack users who are active. Once you exceed the maximum, then the bridge will be disabled until you increase the maximum.

Once you have entered Maximum Slack users, click Purchase (remember you can always go back to this step and increase the maximum number of Slack users if you need more in the future).

  1. A dialogue will remind you of the price per user and ask if you wish to proceed. Click Purchase if you wish to proceed with the Slack Integration

  2. You will have to wait a few minutes while your host is reprovisioned. Once reprovisioning is finished, you are able to bridge Slack to your EMS server using your Element client.

Setup

The setup process for the EMS Slack bridge is the same as the public Slack bridge hosted by matrix.org, explained here

Initiate a DM with a Slack user from Matrix

Teams Bridge

The Teams bridge is no longer available for purchase. This documentation is for existing customers of the bridge only.

Introduction

This guide explains how to set up a Teams bridge with your Element host. You will need to be an administrator of your Teams group to set the bridge up. Connecting to a Teams workspace that you do not control is currently not supported.

Setup

The setup process requires fetching a few details from your Teams workspace.

  1. In the Teams app, not the admin page. Click the three dots next to your Teams, then Get link to team
  2. Click Copy
  3. Paste this link into the Teams Link field on the Teams Bridge setup form on https://ems.element.io/user/hosting#/integrations
  4. Click Link Teams to Element
  5. Follow the Microsoft flow and allow access

Bot Username and Password

The bridge requires a Teams user to be registered as a bot to send messages on behalf of Matrix users. You just need to allocate one user from the Teams interface to do this.

  1. First, you must go to the Azure Active Directory page.
  2. Click users.
  3. Click New user.
  4. Ensure Create user is selected.
    • Enter a User name ex. matrixbridge.
    • Enter a Name ex. Matrix Bridge.
    • Enter an Initial password.
    • Create the user.
    • Optionally, set more profile details like an avatar.
  5. You will now need to log in as this new bot user to set a permanent password (Teams requires you to reset the password on login).
  6. After logging in you should be prompted to set a new password.
  7. Enter the bot username and password into the integration form.

Welcome room

Users can be automatically prompted to link their Teams account to their Element account when they join a room bridged to a Teams channel (for instance, public rooms in the room directory). Ticking the Send a welcome message to new users of the bridge checkbox will make the bridge bot user start a DM with any new joining Element users and let them know how to get connected. If you wish to disable this behavior, leave this box unchecked.

Max Teams users

The bridge is billed based upon the number of participating Teams-side users, so you should set the maximum number of users you'd expect to see using the bridge to ensure your costs meet expectations. If the number of active Teams users exceeds this value, the bridge will be blocked, until you increase the limit. Whatever you set the limit to, you will only be charged for the number of remote users actively using the bridge.

Bot Commands

In a chat with the "Teams Bridge" bot, users can manually connect their Teams account with their EMS account by sending the login command to the bridge bot. The bot will reply with a link that users can use to login

You must authenticate with MS Teams to continue: <login.microsoftonline.com link>

After succesfully login in you should get a message like:

You are now authenticated as **Teams User**

To add a bridged Microsoft Teams team as a space in Element, this can be accomplished by sending the joinspace command. This should add a new space to the sidebar of you Element client with the same name as the teams that you had previously setup with the Bridge, with individual channels showing up as rooms within the new space.

Other commands and option are availble via sending help to the bot. The current help text is show below:

  2. Click the Integrations tab and if you have more than one server, select the server you wish to add the Telegram integration to.

  3. Click on Telegram Bridge in the list of available Bridges.

  4. Enter the maximum number of users in Maximum Telegram users.
    Please note: this is the maximum number of Telegram users who actually send messages over the bridge each month. You are only billed for the number of Telegram users who are active. Once you exceed the maximum, then the bridge will be disabled until you increase the maximum.

  5. If you wish to allow Matrix users who aren't logged in to Telegram to participate in bridged Telegram chats, follow the steps in this section.

Once you have entered Maximum Telegram users, click Purchase (remember you can always go back to this step and increase the maximum number of Telegram users if you need more in the future).

  1. A dialogue will remind you of the price per user and ask if you wish to proceed. Click Purchase if you wish to proceed with the Telegram Integration.

  2. You will have to wait a few minutes while your host is reprovisioned. Once reprovisioning is finished, you are able to bridge Telegram to your EMS server using your Element client.

Bridge Telegram to your Element account

  1. Once the bridge is running, open your Element app. Click on the + next to People.

  2. Create a Direct Message conversation by typing @telegram:example.ems.host (replace the domain with the one of your homeserver). Then click Go.

  3. Wait for the bridge account to join your room.

  4. Open Telegram on your mobile device (iOS or Android) and tap on ≡, go to Settings, and then Devices, and then Link Desktop Device to start the Telegram QR code scanner. You will use this QR code scanner to scan a QR code displayed by your Element client in the next step.

  5. From your Element client, send a login-qr message to the bot to connect to your Telegram account.

  6. A QR code will be displayed. Quickly scan the QR code with Telegram on your mobile device.

  7. On your Element client, you will see Successfully logged in as <username>, and you will see invitations for each of your Telegram channels, groups, and DMs in your Element client. Each Telegram chat is a separate Matrix room. Join one or more chats and start chatting from either your Element app on desktop, iOS or Android or your Telegram on mobile.

Sending a message to a Telegram User

To send a message to a Telegram user, you must first be connected to the bridge (see above).

  1. On your Element client, open the "Telegram bridge bot" room.

  2. Say pm followed by the phone number or username. The phone number must exist in your Telegram contacts.

  3. You will be invited to a DM with that user, and can send messages to them.

Bridging Matrix users without a Telegram account

By default, a Matrix user will have to connect their Telegram account for their messages to be bridged to Telegram. If you provide a bot token, we will use this bot to relay the messages of any Matrix users to Telegram. (Note: relaying is supported for Telegram groups, but is not yet supported for Telegram channels.)

Follow these steps to register a bot account with Telegram.

  1. With your Telegram account, message @BotFather. If talking to BotFather via the bridge using Element, note that all "slash" command messages (eg. /start) sent to BotFather must begin with two slashes instead of one (eg. //start).

  2. Create a new bot by sending the message /newbot to BotFather. The created bot will be the Telegram relay bot used by your bridge. Follow the subsequent prompts to give your bot a display name and a username.

  3. Wait for BotFather to provide you a bot token.

  4. Send the message /setprivacy to BotFather and follow the prompts to set your new bot's privacy settings to "Disabled". This allows your relay bot to bridge all messages sent in a Telegram group, not just messages that mention the bot by name.

  5. Open the EMS control panel for your Telegram bridge and enter the token you received from BotFather in the "Bot token" field, then wait for the page to notify you when your bridge is ready. EMStelegramBotToken.png

  6. In your Element client, view your DM with the Telegram bridge bot and send the ping-bot command. The bot should respond with the ID of your relay bot in Matrix, which indicates that the relay bot has been set up correctly.

  7. In your Element client, invite the Matrix relay bot to any room that bridges a Telegram group that should relay Matrix users' messages to Telegram. A convenient way to do so is to send a message of !tg ping-bot in such a room (which will be intercepted by the bridge bot & won't appear in Telegram), wait for the bridge bot to respond with a "pill" of the relay bot's Matrix ID, click on the pill, and then click "Invite" on the sidebar that appears.

  8. In Telegram, confirm that your Telegram relay bot has joined the group. If it hasn't, you may manually invite your bot to the group (as long as you have permissions to do so) by viewing the group's details, selecting "Add Members", and entering the username of your relay bot that you chose in step 2.
