There are two types of activities for monitoring sensors.
Security-related. If a sensor is on duty, for example, and a contact sensor on a door assigned to Home mode is opened, you’ll receive security-related notifications. If the entry delay is 0 seconds, an alarm will be triggered immediately. You will receive a notification via the Wyze app, and you will also receive an SMS message or a call from Noonlight confirming your safety.
Tech-related. If a sensor has low battery or any other technical issue, you will receive a notification with tips to keep the sensor working properly.
