The REP-21 is the signal amplifier (retransmitter) for the Smart Home Zamel EXTA LIFE system. This amplifier extends the operating range of all devices on the RF 868 MHz network: both in communication between receivers, sensors and transmitters with the EFC-01 controller, and in direct transmitter → receiver control without a controller. A single REP-21 amplifier adds approximately 250 m of coverage in open field. Powered by 230V AC, it installs in a Ø60 mm flush-mount box just like a standard wall switch, with no additional construction work.

This amplifier is the essential tool for making the Smart Home Zamel reliable in large homes, multi-storey houses and buildings with reinforced concrete or solid brick walls. The REP-21 operates completely transparently — no reconfiguration of already-paired devices is needed. Since communication is bidirectional, the amplifier relays both commands to receivers and status feedback returning to the mobile app, keeping the smart home always in sync in every corner of the building.
