The following information provides details on using Gmail with TopView for both outgoing email (Notification) and incoming email (Alarm Acknowledge and information requests).
Google offers free Gmail accounts. They include the use of Gmail's outgoing (SMTP) and incoming (POP) mail servers. TopView can use these 2 mail servers to send and receive email. Note: a free Gmail account has a limit of 500 outgoing emails per day (24 hour period).
Google Workspace allows significantly more per day.
Use Gmail via account linking (OAUTH)
TopView 6.35 added support for linking email to your Google account for outgoing email and incoming email. Authentication between Gmail and TopView leverages OAUTH.
To configure this link, open the TopView Configurator application, then go to "Email-SMS Notification" in the left sidebar. Enable Email-SMS Notification and click the "[Configure]" button. Go to the "Outgoing Email Settings" tab and click the "[Sign in with Google]" button. Follow the prompts to link TopView to your Google account for email.
You may need to add port ":587" to the SMTP address, especially if initial tests fail (port 25 is used by default).
After completing the process of signing in with Google, you can optionally enable incoming email as well.
We recommend using a dedicated email account for emailing with TopView, especially if you set up incoming email. TopView will delete emails from the inbox when processing them.
Use Gmail via SMTP (outgoing) and POP/IMAP (incoming, optional)
With Two Factor Authentication ("more secure")
To use Gmail without enabling access for "less secure apps" in your Google account, you will need to enable Two Factor Authentication.
- Enable Two Factor Authentication for your Google Account
- Create an App Password for TopView to use
- Enter the App Password into TopView's outgoing SMTP password field, and in the POP password field if incoming email is enabled for the TopView configuration.
Changing your Google Account password will automatically revoke any App Passwords.
TopView uses the accepted standard of SSL/TLS for secure communication with email servers. "Less secure" does not indicate that TopView is using bad security practices, it's how Google indicates that there are ways to keep your Google account's password unknown to the TopView application (which is a preferred security practice) as well as allowing your Google account to revoke access to TopView.
Learn more about what "Less secure apps" means from Google.
Notice: Less Secure Apps
Our recommendations previously included instructions using passwords and the "Less Secure Apps" option to send emails through Gmail.
We recommend moving to OAUTH or an App Password. OAUTH access to Gmail has been available for TopView installations since version 6.35.
