Transmission
The Transmission integration allows you to monitor your Transmission BitTorrent downloads from within Home Assistant and set up automations based on that information.
Setup
Your Transmission client must first be configured to allow remote access. In your Transmission client navigate to Preferences -> Remote tab and then click the Allow remote access checkbox.
Configuration
Adding Transmission to your Home Assistant instance can be done via the user interface, by using this My button:
If the above My button doesn’t work, you can also perform the following steps manually:
-
Browse to your Home Assistant instance.
-
In the sidebar click on Settings.
-
From the configuration menu select: Devices & Services.
-
In the bottom right, click on the Add Integration button.
-
From the list, search and select “Transmission”.
-
Follow the instruction on screen to complete the set up.
Integration Entities
The Transmission integration will add the following sensors and switches.
Sensors:
-
sensor.transmission_current_status: The status of your Transmission daemon. -
sensor.transmission_download_speed: The current download speed [MB/s]. -
sensor.transmission_upload_speed: The current upload speed [MB/s]. -
sensor.transmission_active_torrents: The current number of active torrents. -
sensor.transmission_paused_torrents: The current number of paused torrents. -
sensor.transmission_total_torrents: The total number of torrents present in the client. -
sensor.transmission_started_torrents: The current number of started torrents (downloading). -
sensor.transmission_completed_torrents: The current number of completed torrents (seeding).
Switches:
-
switch.transmission_switch: A switch to start/stop all torrents. -
switch.transmission_turtle_mode: A switch to enable turtle mode (a.k.a. alternative speed limits).
Event Automation
The Transmission integration is continuously monitoring the status of torrents in the target client. Once a torrent is started or completed, an event is triggered on the Home Assistant Bus containing the torrent name and ID, which can be used with automations.
Possible events are:
transmission_downloaded_torrenttransmission_started_torrenttransmission_removed_torrent
Inside of the event, there is the name of the torrent that is started or completed, as it is seen in the Transmission User Interface.
Example of an automation that notifies on successful download and removes the torrent from the client:
- alias: "Notify and remove completed torrent"
trigger:
platform: event
event_type: transmission_downloaded_torrent
action:
- service: notify.telegram_notifier
data:
title: "Torrent completed!"
message: "{{trigger.event.data.name}}"
- service: transmission.remove_torrent
data:
name: "Transmission"
id: "{{trigger.event.data.id}}"

Attribute torrent_info
All *_torrents sensors e.g. sensor.transmission_total_torrents or sensor.transmission_started_torrents have a state attribute torrent_info that contains information about the torrents that are currently in a corresponding state. You can see this information in Developer Tools -> States -> sensor.transmission_total_torrents -> Attributes, or by adding a Markdown card to a dashboard with the following code:
content: >
{% set payload = state_attr('sensor.transmission_total_torrents', 'torrent_info') %}
{% for torrent in payload.items() %} {% set name = torrent[0] %} {% set data = torrent[1] %}
{{ name|truncate(20) }} is {{ data.percent_done }}% complete, {{ data.eta }} remaining {% endfor %}
