The sensors and Cloud Connectors can communicate in different radio modes. The normal mode is optimized for low energy usage. If the sensor is unable to reach the Cloud Connector in the normal mode, it will try a different high energy mode, referred to as “Boost” as it will boost the communication range. In DT Studio, sensors transmitting in boost mode have a warning sign on their signal indicators (boost icon).
In Boost mode, the sensors use a different channel, spend longer on transmission and thus drains more energy from the battery.
