Computed Attributes
Alarm attribute should return a string value. Your one returns boolean, as far as I can tell.
I set the attribute as "Alarm", so when it triggered, it used the alarm notification (email).
I didn't see a way to create a custom notification for low battery.
Sounds like you just ignored what I said. The value of the attribute should be a string. More specifically it should be one of the following strings:

Sorry, I was not trying to ignore what you stated. I just didn't understand it until you posted that link. Thank you for that!
I have replaced the expression with this, so I now see an alarm in the tracker state screen. But it is not sending notification emails or triggering web alarms. I have the device set to send alarm notifications, plus I have "Low Battery" alarms selected in the notifications screen. Any ideas on why it is not sending them?
input == "0" ? "lowBattery" : null I suspect there is some problem with notification settings.
I have been over it a dozen times. Maybe you can see something I am missing? All other notifications work as planned. Geo, ignition,...
Device shows low battery alarm
Device had alarm selected
Account notifications
Not sure what the problem could be, but it seems to be configured correctly.
I deleted the device and recreated it. Seems to be working now! Thanks for the help on getting the attributes working!
Is there a way to alarm on "Last Update"? If a tracker has not sent any update in 12 hours, send alarm notification?
I need some help with computed attributes. I keep trying to figure it out on my own, but I'm not getting the results I am looking for.
I need an email triggered when "input" is equal to 0. My device has "input" mapped to the battery, so when "input" is 1 or 2, batteries are good. When input is 0, batteries needs replaced. I would like it to say in the message that "Low Battery". Here is what I tried.
