Installation of Remotely Activated Switches for TWO Airplanes

A hangar without internet access required two wireless remotely controlled switches in an unheated hangar.

The switches were connected to an available Wi-Fi signal using a range extender. from an adjacent hangar.

Each wireless switch provided remotely activated power for either engine heaters, or cabin heaters, or electric tug chargers.

The switches could be remotely activated or they could be programmed with fixed or random schedules.  Additionally the switches could be controlled by different users from different smartphones.
