Systems and techniques are described for a sensor designed to connect to and monitor devices in an ecosystem. In some implementations, a system monitors a property that includes the sensor configured to generate sensor data reflecting an attribute of the property. The sensor includes a host board that generates the sensor data and a core board connected to the host board. The core board identifies a type of the host board and communicates with a monitor control unit. The monitor control unit receives a request for firmware associated with the type of the host board from the sensor. In response, the monitor control unit accesses the firmware and transmits the firmware to the sensor. The core board of the sensor receives the firmware and stores the firmware. The core board receives the sensor data from the host board and transmits the sensor data to the monitor control unit.

Disclosed herein is an electrical connector. The electrical connector comprises a flexible printed circuit comprising electrical elements on a flexible substrate.
