E-mail and Text

I had the configuration down and nothing has changed but I keep getting errors to send an alert to my e-mail and phone.


Any one else having issues?

My settings are correct I think. I wonder if Gmail has tightened up their security with this.

I have use less secure apps selected on their Account Profile page.

The "cannot connect to smtp.gmail.com, port 587: Permission denied" is odd. It's possible that your ISP could be blocking port 587, but I'd be surprised.

Try changing the port to 465 and see if works.

Just pulled the SD card and reflashed the firmware from scratch.
Tried 465 and I posted the Log

Is there any chance you've got ipv6 enabled on your router?

Not that i can see

I have no idea what could cause that, I mean where would a "Permission denied" error come from in connecting? The man page for connect() says you can only get EACCES connecting to a UNIX socket.

I just tried with the default heatermeter.com credentials on port 587 sending to a gmail account, worked fine.
Changed the host to smtp.gmail.com, I get a proper SMTP error code '535-5.7.8 Username and Password not accepted...', not permission denied error.

You can try sending a test with the default credentials to see if it is blocked too, which would indicate the ISP blocking maybe?

I'm not sure if I have the same problem, as I have not checked the logs, but I too can not get email or text working..

Comcast internet

FWIW, if you're forwarding outbound email through your ISP, you may have some funny issues to work through. If I set my return address to anything but my ISP's domain (but still a valid email address domain,) the pages get silently dropped. One of these days I may need to tinker with using Google's outbound SMTP gateway as my general purpose smart mail handler. That may become academic, as I'm really hoping to switch ISPs at home fairly soon (symmetric 100mbps fiber to the house.)

Edit: Empirically, this appears to only be an issue with text messages to my phone, and I see all messages in my SMTP service logs.

One other thing to be aware of. Some systems, such as AT&T Cellular, will silently drop SMS messages sent from an email domain that fails to resolve, such as john.q.public@donotreply.com.

ssh into your heatermeter and run this command to see if it works.

Just checked again today and it worked!!

I did nothing different. I'm using 465, but both the e-mail and text work. Must have been an off day or something.
