I have a number of devices, leak sensors, hidden door switches that are set up to send text messages to my iPhone when they change state.  A few weeks ago I stopped getting the messages.  When going to the Settings/Groups tab and selecting any of my groups I get Mail server failure [Password not accepted] error message.

 

If it helps with troubleshooting, the recipient is [mycellnumber]@txt.att.net. 

 

As mentioned earlier this has worked flawlessly for over a year.

 

In the SMTP section I'm showing smtp.gmail.com, using port 587.  I don't think this is important since I never use the email function.

 

Thanks for any help you can offer

Your firmware version and UI version may help with the diagnosis.

Sorry I missed that.

The smtp address is absolutely important. Essentially you are Emailing AT&Ts Email to SMS server. You must have your gmail username and password populated.

I didn't mean to imply that the SMTP settings were blank.  They are:

SMTP Server    smtp.gmail.com       SMTP Port  587

User ID  myaddress@gmail.com       Password  *************

From  Ron:myemailaddress@gmail.com   Timeout   1000

Use TLS is checked

In order to ascertain that the password was correct, I went to the Google site, changed my password, and then updated it in the SMTP settings area

Still no luck!

Have you enabled 'Allow insecure apps' in your Google profile? That's necessary to allow generic SMTP clients to authenticate.

 

See https://support.google.com/accounts/answer/6010255?hl=en

 

Also, if you enabled 2fa on your Google account, you'll need to get an application specific password to use for authentication.

Thank you, that was the answer.  In the meantime I found that checking the "Use Default" box clears everything from the SMTP Settings area and now I just get a text message from ISY whenever one of my sensors changes state.
