Abstract

Concepts and technologies are disclosed herein for alarm initiation when a sensor is intentionally jammed. According to one aspect disclosed herein, a connected home system can include a controller device and a sensor device. The sensor device can include a processor and memory. The memory can store sensor instructions that, when executed by the processor, cause the sensor device to perform sensor operations. In particular, the sensor device can detect a jamming signal originating, for example, from jamming device that is intentionally attempting to jam operations of the sensor device. The sensor device can determine whether the jamming signal is above a jamming alarm threshold. If the sensor device determines that the jamming signal is above the jamming alarm threshold, the sensor device can generate a jamming alarm event that is directed to the controller device. The sensor device can send the jamming alarm event to the controller device.
