The IMAP integration is observing your IMAP server. It can report the number of unread emails and can send a custom event that can be used to trigger an automation. Other search criteria can be used, as shown in the example below.

{% include integrations/config_flow.md %}

Gmail with App Password

If you’re going to use Gmail, you need to create an App Password.

1. Go to your Google Account
2. Select Security
3. Under “Signing in to Google” select App Passwords
4. Sign in to your Account, and create a new App Password for Gmail.
5. Then you can setup the intergation as below:
   • Server: imap.gmail.com
   • Port: 993
   • Username: Your full email address
   • Password: The new app password

Configuring IMAP Searches

By default, this integration will count unread emails. By configuring the search string, you can count other results, for example:

• ALL to count all emails in a folder
• FROM, TO, SUBJECT to find emails in a folder (see IMAP RFC for all standard options)
• Gmail's IMAP extensions allow raw Gmail searches, like X-GM-RAW "in: inbox older_than:7d" to show emails older than one week in your inbox. Note that raw Gmail searches will ignore your folder configuration and search all emails in your account!

Selecting a charset supported by the imap server

Below is an example for setting up the integration to connect to your Microsoft 365 account that requires US_ASCII as charset:

• Server: outlook.office365.com
• Port: 993
• Username: Your full email address
• Password: Your password
• Charset: US-ASCII

Selecting an alternate SSL cipher list (advanced mode)

If the default IMAP server settings do not work, you might try to set an alternate SLL cipher list. The SSL cipher list option allows to select the list of SSL ciphers to be accepted from this endpoint. default (system default), modern or intermediate (inspired by Mozilla Security/Server Side TLS)

The SSL cipher list is an advanced setting. The option is available only when advanced mode is enabled (see user settings).

Troubleshooting

Email providers may limit the number of reported emails. The number may be less than the limit (10,000 at least for Yahoo) even if you set the IMAP search to reduce the number of results. If you are not getting expected events and cleaning your Inbox or the configured folder is not desired, set up an email filter for the specific sender to go into a new folder. Then create a new config entry or modify the existing one with the desired folder.

Using events

When a new message arrives that meets the search criteria the imap integration will send a custom event that can be used to trigger an automation. It is also possible to use to create a template binary_sensor or sensor based the event data.

The table below shows what attributes come with trigger.event.data. The data is a dictionary that has the keys that are shown below:

{% configuration_basic %} server: description: The IMAP server name username: description: The IMAP user name search: description: The IMAP search configuration folder: description: The IMAP folder configuration text: description: The email body text of the the message (only the first 2048 bytes will be available) sender: description: The sender of the message subject: description: The subject of the message date: description: A datetime object of the date sent headers: description: The headers of the message in the for of a dictionary. The values are iterable as headers can occur more than once.

{% endconfiguration_basic %}

The event_type for the custom event should be set to imap_content. The configuration below shows how you can use the event data in a template sensor.

{% raw %}

template:
  - trigger:
      - platform: event
        event_type: "imap_content"
        id: "custom_event"
    sensor:
      - name: imap_content
        state: "{{ trigger.event.data['subject'] }}"
        attributes:
          Message: "{{ trigger.event.data['text'] }}"
          Server: "{{ trigger.event.data['server'] }}"
          Username: "{{ trigger.event.data['username'] }}"
          Search: "{{ trigger.event.data['search'] }}"
          Folder: "{{ trigger.event.data['folder'] }}"
          Sender: "{{ trigger.event.data['sender'] }}"
          Date: "{{ trigger.event.data['date'] }}"
          Subject: "{{ trigger.event.data['subject'] }}"
          To: "{{ trigger.event.data['headers']['Delivered-To'][0] }}"
          Subject: "{{ trigger.event.data['headers']['Subject'][0] }}"
          Return_Path: "{{ trigger.event.data['headers']['Return-Path'][0] }}"
          Received-first: "{{ trigger.event.data['headers']['Received'][0] }}"
          Received-last: "{{ trigger.event.data['headers']['Received'][-1] }}"

{% endraw %}

Example - keyword spotting

The following example shows the usage of the IMAP email content sensor to scan the subject of an email for text, in this case, an email from the APC SmartConnect service, which tells whether the UPS is running on battery or not.

{% raw %}

template:
  - trigger:
      - platform: event
        event_type: "imap_content"
        id: "custom_event"
        event_data:
          sender: "no-reply@smartconnect.apc.com"
    sensor:
      - name: house_electricity
        state: >-
          {% if 'UPS On Battery' in trigger.event.data["subject"] %}
            power_out
          {% elif 'Power Restored' in trigger.event.data["subject"] %}
            power_on
          {% endif %}

{% endraw %}

Example - extracting formatted text from an email using template sensors

This example shows how to extract numbers or other formatted data from an email to change the value of a template sensor to a value extracted from the email. In this example, we will be extracting energy use, cost, and billed amount from an email (from Georgia Power) and putting it into sensor values using a template sensor that runs against our IMAP email sensor already set up. A sample of the body of the email used is below:

Yesterday's Energy Use:                             76 kWh
Yesterday's estimated energy cost:                  $8
Monthly Energy use-to-date for 23 days:             1860 kWh
Monthly estimated energy cost-to-date for 23 days:  $198

Below is the template sensor which extracts the information from the body of the email in our IMAP email sensor (named sensor.energy_email) into 3 sensors for the energy use, daily cost, and billing cycle total.

{% raw %}

template:
  - trigger:
      - platform: event
        event_type: "imap_content"
        id: "custom_event"
        event_data:
          sender: "no-reply@smartconnect.apc.com"
  - sensor:
    - name: "Previous Day Energy Use"
      unit_of_measurement: "kWh"
      state: >
       {{ trigger.event.data["text"]
         | regex_findall_index("\*Yesterday's Energy Use:\* ([0-9]+) kWh") }}
    - name: "Previous Day Cost"
      unit_of_measurement: "$"
      state: >
        {{ trigger.event.data["text"]
          | regex_findall_index("\*Yesterday's estimated energy cost:\* \$([0-9.]+)") }}
    - name: "Billing Cycle Total"
      unit_of_measurement: "$"
      state: >
        {{ trigger.event.data["text"]
          | regex_findall_index("\ days:\* \$([0-9.]+)") }}

{% endraw %}

By making small changes to the regular expressions defined above, a similar structure can parse other types of data out of the body text of other emails.
