You can set it to receive an alert notification on your phone but no email or texts. You don't do this under rules however, you do this under devices. Select the small wrench and set "Notify Me" to Always (always), When I'm Away (when the router mode is set to away) or Never (never). This will cause a notification on your iPhone when the conditions are met but you must make sure notifications from the app are allowed (this done in settings).
