We do not support setting up alerts or notifications via our sensor platform directly.
Our platform is designed to completely separate the domain knowledge ("what constitutes an alarm situation") from the raw data ("the temperature is -1 degree").
An alarm or notification service would typically be implemented by sending data in real-time to your (or a partners) cloud solution. Based on this data, it would then react to this in their cloud solution, based on business logic, and send alerts via the right channels to the right people.
Please also have look at our guide on Sending SMS notifications.
