Product Manual

This is a wireless GSM remote control switch that connects to 3G/4G GSM cell phone networks that exist in almost every country on earth.

iPhone and Android apps are available for this product.

This device does not come with a SIM card. Please contact your local cell provider and purchase a standard 3G/4G SIM card, and activate it on a pay as you go plan.

The device has 7 independent relay switches. The first relay switch is activated by calling the SIM cards cell phone number. The device will then reject the call without answering and trigger the first relay. There are no call costs incurred when dialing the unit; it will recognize an authorized telephone number calling it and reject the call without answering. The first relay has two modes, momentary and latching mode. When receiving a phone call in momentary mode, the first relay will turn on for a pre-programmed amount of time. This time period can be programmed by the user and can be anywhere from half a second to many days. When receiving a phone call in latching mode, the device will simply change state. If the relay was on before, it will be turned off. If it was off before, it will be turned on.

All 7 relays can be controlled by SMS either individually, or all of them at the same time with a single command.
