The Wireless Temperature Sensor measures the surrounding temperature and wirelessly transmits the result to a Cloud Connector (Gateway) via SecureDataShot™ technology. The Cloud Connector will relay the temperature reading to a Cloud service. The readings are performed at 15-minute heartbeat intervals.
The Wireless Temperature Sensor has touch functionality for simple installation and use.

Is it possible to measure temperature more often?
The sensors are fixed to measure the temperature every 15 minutes. If a more frequent reading is required, we offer the Wireless Temperature Sensor (EN12830) sensor which measures the temperature every 5.5-minute.
Also please note that most real-world temperature changes are very slow compared to our default 15-minute reporting interval. To take a concrete example, an air conditioner that has been configured to a specific temperature will take one hour or more to actually cool down, or heat up, a room to that temperature, depending on the temperature change. During this time, you will have multiple data points to monitor the change in temperature.
