You can set the alerts for your Kunas by going into your App Settings. First, click the Gear icon in the bottom toolbar.
Then select Alerts:
Here, you'll be presented with a menu that allows you to turn on alerts globally (for all of your Kunas at the same time) or individually for each Kuna. This is useful if, for example, you want to get alerts from your Front Door Kuna, but not your Garage Kuna.
Please note that these settings are unique to your account. If you share your Kuna with another user, they can set their own alert settings.
If you have your alerts turned on, but still aren't receiving then, click here.
