Hi @user0071. You’re able to receive notifications when a Contact Sensor is opened, regardless of the Mode that your Ring Alarm system is in. However, it sounds like you are referring specifically to a notification if a Contact Sensor has been open for a certain amount of time. Currently, that is not an option in the Ring app. Other neighbors have requested this before, which you can find here on our Feature Request board. Feel free to add a comment and vote on that request. Thank you!
