The GSM-AUTO is a GSM remote control switch, it connects to the mobile phone network and like a mobile phone has its own telephone number. The GSM-AUTO is activated by calling its phone number, it will recognise an authorised telephone number calling it, reject the call without answering and switch on or off the device connected to it, because it rejects the call without answering there are no call costs incurred.
It has 2 independent relay switches, these can be programmed to switch on for a pre-determined length of time whenever the GSM-AUTO is called.
The relay switches can also be temporarily or permanently switched on or off by sending the GSM-AUTO a sms text message command. It can report the relay status by sending a text message.
Applications include the remote control of central heating, lighting, engine pre-heaters, aviation engine heaters, irrigation systems, water well pumps, pumping stations, cabin heaters, resetting & reboot of remote servers and routers, arming and disarming security systems.
