3. TrueNas Scale Notifications

1. Setup SMTP Email
Unfortunately, TrueNas does not offer webhooks for notifications yet so a good alternative is Email. To setup email go to System > General Settings > Email 
 
 Then simply fill in your SMTP credentials. If you don't know how to do this check SMTP Email Setup 
 
  

2. Connect Notifications to Email
Once, your email is setup in TrueNas scale you can use that to receive notifications on all kinds of changes and updates within your TrueNas system. To do this 
 1.  Go to System > Alert Settings > +Add Alert service 
 2. Then simply select Email 
 3. I would recommend to set the level at "Notice". The level you set here is the minimum level you will receive notifications from. The lowest being INFO and the highest being EMERGENCY 
 Alright sweet! that was setting up your email notification service. Just to check if it works you can send your self a Test Email.  
 Categories 
 Now, there are simply to many alerts you can get notified from, and you should just look for yourself which things you want to get notified from. By default you get an alarm for any critical change in your system so you don't need to edit to much. However, just have a look throughout the categories and if you want to get a notification from something just make sure it is at least above the minimum level threshold you set for your Email Alert service. 

3. TrueNas System Updates Notifications
Just as with Proxmox we would also like to receive a notification when a new update for our TrueNas system comes available. Luckily TrueNas allows this.  
 
 Go to System > Alert Settings > Category 
 Select the category System 
 Then scroll all the way down until you find Update Available.  Then make sure it is set to Notice, s.t you will receive a notification when a TrueNas update is available.
