Jablotron DAVID - GSM Communication for Remote control and automation of your home


A RELAY with remote control by mobile phone

Two output terminals (X or Y) can be used as:
  • An SMS-controlled switch. SMS texts for switching particular terminals on/off are configurable (e.g. "light on", "light off" and "sunblind close", "sunblind open"). Any such instruction can be automatically echoed by David sending you an SMS report.
  • A time-switch which can be activated remotely via a mobile phone.(the switch-on period is configurable from 1 second to 10 hours).
  • A relay with dialling-in remote control. Up to 50 tel. numbers can be authorized for each relay. Because calls are not answered dialling-in control within GSM is free of charge. (David only checks the caller’s number and – if the number is authorized – responds with relay activation.) This can be used for parking access control, door lock control, switching lights etc.

Each authorized number can have a limit to the number of calls. For example, when the customer is only allowed to open the parking lot entrance for 30 times at most, any further access is denied to him/her. The customer can then be re-authorized for entrance control via SMS by the administrator.
