Building a Low-Power Wireless "Smart Office Labelling System"

E-Ink displays have a few unique benefits, such as low static power usage and high-contrast images. These features make them suitable to build for various applications, such as e-book readers and status displays that do not require frequent updates.
A possible application of E-Ink displays are smart office labels, which can be placed in front of an office door to signal the availability of the person sitting inside (e.g., "Busy - Do not disturb", "Available - Please walk in", "Away - Out for lunch"), similar to the concept picture below. Our goal is to build a low-cost system that can be used to control wirelessly several labels at once (e.g., using Bluetooth Low Energy radios) and that is easy-to-use (e.g., that can be controlled using a smartphone).
