How to enable email alerts

To enable the email server within UniFi, go to 'Settings'

Then to 'System'

Then, 'Advanced'

Scroll down to 'Email Services' and you can choose between the various options.

UniFi lets you choose between using the SSO email service Ubiquiti provides or using a custom SMTP option. The SSO option is only available if you have connected your UniFi server to the unifi.ui.com dashboard for remote access.

Once the SMTP server has been enabled, you can go to System Log

Then 'Settings'

Under 'UniFi Device Connection Change' - click on the email icon and from now on you'll get an email for when a UniFi device goes offline and comes back online

One last step is to check that email alerts are enabled for your user account. To check this go to 'Admins'

Click on your user account and user 'Push Notification Settings' check that Email is activated

How to enable push notification alerts

For push notifications, you first need to check that the UniFi server you are wanting alerts from has been added to the mobile device you want to get alerts on. To do this see our guide here.

Once done, check that push alerts are enabled for your user account. To check this go to 'Admins'

Click on your user account and user 'Push Notification Settings' check that Mobile is activated

Next, go to System Log

Then Settings

Under 'UniFi Device Connection Change' click on the bell icon and from now on you'll get an notification for when a UniFi device goes offline and comes back online
