The sub-unit (slave) extends your SMS master socket by a further, independent switching unit.
All the functions of the main socket are available without the need for another SIM card.
Applications such as controlling the heater, rebooting the router or controlling the irrigation system can now be controlled simultaneously via SMS.
This SLAVE or satellite unit communicates with the SMS master socket via radio
and is also addressed and switched via the main unit.
You can also make all settings for the subunit, such as time switching,
temperature query, temperature alarm, temperature-dependent switching, etc.
This unit does not require a SIM card and can only be operated in conjunction with a main unit.
No WLAN (WiFi) network is required !
The connection to the MASTER unit is simple
The technical data and specifications of the main socket also apply to the SMS slave socket.
