Displaying, on a screen of a mobile device having a camera, a real-time image from the camera; displaying, on the screen, feedback indicating positioning of a second device captured in the real-time image; determining that the positioning of the mobile device relative to the second device is sufficient to trigger an action on the second device; and triggering the action on the second device using the mobile device.

Positioning feedback for device-to-device communications

After installation, a device may be not yet powered. It may be awakened by receiving a flash of light of sufficient frequency and amplitude. After waking, the device decodes the message to determine its next action, and, upon request sends an authentication message. This enables a single user action to wake the device up and set it up with networking credentials. The same process may be used to wake the device outside of a normal sleep-wake cycle.

External activation of quiescent device

A device that runs on solar and battery power determines a current cycle energy budget by looking at a previous cycle or cycles energy accumulation and previous cycle or cycles unexpected expenses. The energy budget will then be the energy accumulation minus the unexpected expenses, normalized for cycle length. Based on the energy budget, an operating mode is chosen. The operating mode determines how often certain actions are taken. The device then runs for a cycle length based of the operating mode.

Device energy use determination

After installation, a device may be asleep. A light signal device may send a message to the sleeping device to wake it up. This wake-up message may comprise the light signal device sending programmed light signals, the programmed light signals in modified morse code. An authentication part may also be included in the message. The light signal device may request an authentication message from the sleeping device.
