Operation
The relay operates in the GSM 900/1800 mobile communication network of any operator operating in Poland (no simlock). The device must have an active SIM card in order to make calls and perform the set functions. The relay has two controllable relay outputs, through which functions of switching on and off controlled receivers are realized, and two high-voltage inputs, through which functions of notifications about tripping controlled devices are realized. Commands and notifications are specific SMS texts exchanged between the controller and the user's phone.

Functions
* 2 control outputs ON/OFF (8A 250 V AC)
* temporary control of outputs, e.g. for 30 s (1 s÷600 min.)
* 2 alarm inputs (160÷260V AC direct connection)
* option of triggering by signal appearance and disappearance (0/1)
* notifications to 5 phone numbers for each input
* inquiries about the status of inputs and outputs
* redefinition of names of inputs and outputs, e.g. WE1-> PUMP; WE2-> BURGLARY
* option of automatic responses about command execution
* option of automatic restoration of outputs' state after power return
* access control via password
* no simlock

Notes on SIM cards
SIM card of the relay P01:
* it is recommended to use a SIM card with a tariff so-called telemetry/m2m. Ask at your GSM operator!
* the first activation of the SIM card of the controller should be done on any user phone (send SMS or make a voice call)
* we recommend clearing the inbox memory;
* for regular tariff (not telemetry) it is recommended to disable any additional operator services assigned to the SIM card, e.g. free SMS notifications, voicemail, operator IVR voice menu for free notifications, etc.
* the first startup of a SIM card on the relay may take up to several minutes. This is due to the registration of an unknown device model and finding the correct system configuration by the operator.

SIM card of the user's phone:
* SMS input mode should be set as TEXT (not UNICODE)! By default, GSM operators set TEXT mode. If the relay ignores SMS, check the settings and change to the correct one.
