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.

Extend your temperature sensor up to max. 3m
(sensor is already in the unit)

Practical for use e.g. in a cold room.

Please note that the use of extension cables can lead to slight deviations in the temperature measurement.

For a more accurate measurement, we have temperature sensors on offer.

Safe temperature control via SMS
This socket is an easy way to control the power supply and temperature of sensitive products. All you have to do is insert a standard SIM card into the device and plug it in, and you can check temperature values or set a temperature range.

The temperature sensor is compatible with our master and slave SMS sockets.

The sensor covers a wider temperature range (-50° to 100°), is more accurate and waterproof.

Can be used in the freezer or in a water basin.
