emailtest fails with yahoo

Configuration file for Raspi-Sump

All configurations should be done in this file.

This file should be located in the /home/pi/raspi-sump directory

[gpio_pins]

Raspi-Sump uses the actual GPIO numbers and not the Pi numerical pin

numbers. You can use any available GPIO's for Trig and Echo.

Trig pin sends the signal. Value is the number of the GPIO

on the RaspberryPi

trig_pin = 17

Echo pin receives the signal. Value is the number of the GPIO

on the RaspberryPi

echo_pin = 27

[pit]

Unit of measure. You may choose to use metric or imperial measurements.

The unit variable must be set as metric or imperial and is case sensitive.

Any other setting will cause an error.

unit = imperial

critical_water_level is the water level in the sump pit at which point an

email alert should be triggered.

If unit = metric then critical_water_level = centimeters

If unit = imperial then critical_water_level = inches

critical_water_level = 18

The pit_depth is the distance between the sensor and the bottom of the

sump pit.

Like critical_water_level, enter centimeters for metric and inches for

imperial

pit_depth = 21

rsump.py should be run with a cron job. However cron is limited to

1 minute as its minimum interval. If you need to monitor the sump level

more frequently you can set reading_interval to the desired time in seconds.

Default is 0 meaning only one reading will occur and the program will exit.

If set to 0 call the script with a cron job and select your interval there.

If setting to a value other than 0 you should run rsumpmonitor.py from a cron

job at a regularly interval to monitor the health of the rsump.py process.

rsumpmonitor.py is part of the raspisump software. See documentation for

details.

reading_interval = 0

The temperature variable will adjust the speed of sound to reflect

the normal temperature of your basement.

If unit = metric then enter the temperature in Degrees Celcius.

If unit = imperial then enter the temperature in Degrees Fahrenheit.

temperature = 70

Raspi-Sump can also be used in situations where you would want to check if

the water_level is too low. Sump pits are concerned with high water levels

but a drinking water cistern would require an alert when it is low. For that

reason you can set the following value to 'low'. Leave this value as is unless

you specifically want alerts when the water drops below a certain level.

alert_when = high

[charts]

This section deals with charting

line_color takes a hex color value.

e.g

red(ff0000), black(000000), blue(0000ff), default rsumporange(FB921D)

line_color = FB921D

[email]

Important information for Gmail users only.

***Please read this thread on allowing applications to send

***email from Googles Gmail service which have implemented ouath2.

***https://github.com/alaudet/raspi-sump/issues/6

***Raspi-sump does not implement oauth2 for authentication so you will need

***to use a workaround for gmail to send alerts.

Set an appropriate interval for alerts. If you are taking readings at short

intervals it is possible to bombard yourself with SMS text messages when the

water reaches a critical level. For example if you are taking a reading

every minute or less an SMS Email alert will be sent each time the reading is

taken. By setting the alert_interval this allows you to receive an email

alert at a more appropriate time interval. Readings will continue and will

be logged but SMS text alerts will only be sent as you define it.

alert_interval is set in minutes. The default is 5 minutes if this value is not present.

alert_interval = 5

SMTP Server requires authentication (0=No, 1=Yes)

If using localhost or possibly your ISP email this value

will most likely be 0. Check your ISP's configuration docs.

For Gmail set this to 1 and fill out the corresponding

username and password values in this file.

smtp_authentication = 1

SMTP Server uses TLS (0=No, 1=Yes)

If using localhost or possibly your ISP email this value

will most likely be 0. Check your ISP's configuratin docs.

For Gmail set this to 1.

smtp_tls = 1

If server requires authentication enter username and password.

For Gmail, activate these values with your gmail username and password.

username = billotronic@yahoo.ie password = xxxxxx

SMTP Server and Port

example -- smtp_server = smtp.gmail.com:587

if using a SMTP server on the Pi use localhost:25

smtp_server = smtp.mail.yahoo.com:587

Notifications will be sent to the following address

example -- email_to = cellnumber@wireless_carrier (for sms email alerts)

You can also use a regular email address

To add multiple recipients seperate email addresses with a comma.

e.g. Adding a single recipient

email_to = single_email@somewhere.com

#

e.g. Adding multiple recipients

email_to = recipient1@somewhere.com, recipient2@somewhere.com

Don't forget the space after the comma in the line above.

To test emails, run the command 'emailtest' from the pi terminal.

email_to = xxx@xxx.com

Notification will be coming from the following address.

You can enter your email address here as the sender.

example email_from = Raspi-Sump youremail@yourprovider.com

email_from = Raspi-Sump-Notifier billotronic@yahoo.ie

Set a heartbeat sms or email interval in order to regularly test that your

notifications are working as intended.

0 = No notifications

1 = Send notifications

heartbeat = 1

Set the frequency of the sms/email heartbeat notifications.

Values can be set to any number and are in minutes.

For reference;

daily = 1439 minutes

weekly = 10079 minutes

Monthly = 43199 minutes

heartbeat_interval = 10079

Raspbian Bullseye on Pi Zero W, up to date.

For the life of me I cannot seem to figure out what the problem is. Thanks for this awesome project.

Ok, been looking into this one and I focused on this message in the error

ssl.SSLZeroReturnError: TLS/SSL connection has been closed (EOF) (_ssl.c:1123)

It appears that yahoo prefers ssl to tls for encryption. However it should fall back to tls if ssl does not work.

Accorging to their site you should use port 465 and not 587 for your server port. I am not convinced it will fall back to TLS though so you will need to try it.

Please use port 465, try again and report back the error you get if it does not work.

[alaudet]

Now that I read more I dont think that will work at all. Yahoo should support port 587 tls but maybe they no longer do. TLS still works with gmail but most likely I will need to patch my code to support ssl smtp connections as this is the preferred way even at gmail, although they support tls. I suspect it may be just a matter of time before they don't.

[alaudet]

Raspi-sump now supports ssl email as of version 1.8.1

Enable ssl in raspisump.conf by adding smtp_ssl = 1 below the smtp_tls entry and make sure to change to smtp_tls = 0

you must also use the proper port for ssl, in most cases it will be 465

e.g.

# SMTP Server uses TLS (0=No, 1=Yes)
smtp_tls = 0
# SMTP Server uses SSL (0=No, 1=Yes)
smtp_ssl = 1

smtp_server = smtp.gmail.com:465
