Hey there, I want to read mails with the IMAP integration of Home Assistant. This works very well. But I want to save the last 10 mails that were received and according to my conditions. I tried several options like MQTT but it’s problematic when you want to use an JSON array then and also use the data again. I need to be able to read it again after being saved.
I really don’t know how to do it. I tried it with notify.file but got several problems that nothing would be saved. The last try for my automation now looked like this:
alias: Save mails
description: >-
Saves the last 10 mails as JSON-Array and updates variables.
triggers:
- event_type: imap_content
id: custom_event
trigger: event
actions:
- variables:
new_email: |
{{
{
"subject": trigger.event.data.subject,
"sender": trigger.event.data.sender,
"message": trigger.event.data.text,
"folder": trigger.event.data.folder,
"server": trigger.event.data.server,
"username": trigger.event.data.username,
"search": trigger.event.data.search
}
}}
- variables:
current_emails: >
{% set history = states('sensor.email_history') %} {{ (history if
history not in ['unknown', 'unavailable', 'None'] else '[]') | from_json
}}
- variables:
updated_emails: >
{{ (current_emails + [new_email])[-10:] }}
- data:
topic: email/history
payload: "{{ {'emails': updated_emails} | tojson }}"
retain: true
action: mqtt.publish
But this won’t work. In the end, I really want to be able to see a list in a dashboard with the latest 10 subjects of mails. But I don’t know how to do this. Having 10 separate sensors for this might be possible somehow but sounds ridiculous to me.
