Can't send email

[hamanjam]

First off, thanks for maybe the simplest setup I've seen for this. I'm getting an error when trying to send email notifications. Whn I start up, I can connect and everything looks great. When I disconnect the sensor to simulate an open door, I get a message on the command line after several minutes:

root@ol7:/home/pi/garage-door-controller# /etc/rc.local
My IP address is X.X.X.X
root@ol7:/home/pi/garage-door-controller#
root@ol7:/home/pi/garage-door-controller# Unhandled error in Deferred:

Here is my config.json with the email settings:

{
"config":{
"use_https":true,
"use_auth":true,
"use_alerts":true,
"use_openhab":false
},
"alerts":{
"time_to_wait":10,
"alert_type":"smtp",
"smtp":{
"smtphost":"smtp.gmail.com",
"smtpport":587,
"smtp_tls":"True",
"username":"fromuser@gmail.com",
"password":"mypass",
"to_email":"touser@hotmail.com",
"subject":"Garage door test"
},

Have you tried smtpport 465?

Just tried it and same thing.

I installed exim on the Pi and tried it as well sending mail locally also. I can manually send mail from command line through exim. I can telnet to both ports at gmail

Started completely over and got the same error. Searching turns out that's a problem with a version of "twisted" I was able to run "pip install Twisted" and cleanup with more info. Now, the app hangs and stops responding to door events but at least I get more in /var/log/messages:

Unhandled error in Deferred:

Found the first issue I'm having:

Line 178 in controller.py:
sys.syslog("Error sending email: " + str(inst))

Change to:
syslog.syslog("Error sending email: " + str(inst))

Now, in var/log/messages I see the following but no crash (no email but making progress)

Fixed. My problem in config.json was the port number was in quotes from testing previously. Once I set up the app password in gmail, I was able to send email.
