Using this GSM switching control system you will be able to activate your heater from now on already on your way to the airport and the engine of your aircraft will be already pre-heated when you arrive. Even if you are not planning to go flying you can use the remote control just to keep your engine and battery at a certain temperature regularly.
The iSocket is designed for remote switching of electrical equipment. It´s just to connect to a socket outlet in your hangar and to be equipped with a standard SIM-card from most GSM-operators. Now it´s very easy to activate the switch just via SMS or phone call.
