CallFree devices are GSM remote controllers that are activated by calling or texting its mobile phone number. This will switch any device, it is connected to, on or off. There is no call costs incurred as the GSM controller will reject the call without answering.

The CallFree remotes can be connected to a wide range of devices such as electric gates, central heating, burglar alarms, passive infrared sensors, water level or leakage sensors, Carbon Monoxide detectors and many more.

The relay switches can also be temporarily or permanently switched on or off by sending the GSM a SMS text message command. It can report the relay status by sending a text message.

The CallFree remote control is available for 2G and 3G mobile phone networks.

Applications include GSM control of heating, lighting, irrigation systems, pumping stations, access control of gates, re-setting of remote servers and routers, control of remote scientific instruments.
