2-channel rocker - switch - style transmitter with temperature sensor rnk-22
The radio transmitters RNK-22 and RNK-24 are intended for sending control signals and temperature information as part of the EXTA LIFE system. They perform such tasks as switching on/switching off, brightening /dimming, controlling roller blinds. The implemented packet encryption algorithm increases data transmission security. The temperature information, in conjunction with the EFC-01 controller functionality, may be used for heating systems control. In their size and appearance, the transmitters resemble traditional, rocker-style light switches. Battery operation and a complete lack of any wiring cables allow for a wide range of applications.
Transmitters may be affixed to any surface (except metal), in any location in the room. The possibility of having many transmitters assigned to one receiver gives a lot of freedom in designing the controlling portion of the installation.

Exta life is a solution that is comfortable, completely safe, and also affordable.

Bidirectionality, enhanced logical functions, encryption of transmitted data, ability to control devices remotely, automatic component detection, and free-of-charge receiver auto-updates are features that definitely make exta life smart home stand out among other solutions currently available on the market.
The exta life system allows for comfortable and efficient control of lights, roller blinds, entry gates, heating, and other electrical devices, not only with the help of radio transmitters, but also by using smart phones and tablets from any location world-wide.

function image
rocker switch attachable to any surface
The rocker-switches RNK-22 and RNK-24 can be mounted on any surface. This is especially important in the case of large glass surfaces, and for wooden homes. A switch can be at any time moved to a more convenient location.

temperature measurement in each room
Thanks to a temperature sensor being integrated into the switch, a real-time room temperature control is possible.

* Temperature is measured in the transmitter every 15 minutes. If the current measurement differs from the previous one by a value > ±0.3°C, the transmitter sends the result of the
measurement (e.g. to a controller). If the temperature stays the same, a measurement result is sent out once every 20 times a measurement is taken. The temperature information is sent out also after 5 consecutive presses of any button on the transmitter.
The temperature sensor on the RNK-22 and RNK-24 transmitters can be entirely switched off.
