Python Help
1

With following python code ,i can send email in python3.11 console:

import smtplib, ssl
from email.mime.text import MIMEText
from email.mime.multipart import MIMEMultipart

def sendemail(subject="title",content="info",sender_email=None,receiver_email=None,password=None):
    port = 465
    smtp_server = "smtp.qq.com"
    message = MIMEMultipart("alternative")
    message["Subject"] = subject
    message["From"] = sender_email
    message["To"] = receiver_email
    text = content
    part = MIMEText(text, "plain")
    message.attach(part)
    context = ssl.create_default_context()
    with smtplib.SMTP_SSL("smtp.qq.com", port, context=context) as server:
        server.login(sender_email, password)
        server.sendmail(sender_email, receiver_email, message.as_string())

Call the sendemail function:

sendemail(sender_email='x1@qq.com',receiver_email='x2@qq.com',password='xxxx')

I can receive an new email in my x2@qq.com,now to set my homeassistant’s configuration.yaml:

notify:
  - name: "send_email"
    platform: smtp
    server: "smtp.qq.com"
    port: 465
    timeout: 15
    sender: "x1@qq.com"
    encryption: starttls
    username: "x1@qq.com"
    password: "xxxx"
    recipient:
      - "x2@qq.com"
    sender_name: "send by homeassistant"

Restart my homeassistant,and call the service,some error in log:

cat  /home/homeassistant/.homeassistant/home-assistant.log

Make port and protocol matched:

notify:
  - name: "send_email"
    platform: smtp
    server: "smtp.qq.com"
    port: 587
    encryption: starttls

Or:

notify:
  - name: "send_email"
    platform: smtp
    server: "smtp.qq.com"
    port: 465
    encryption: tls
