Summary

The MultiTRX is a compact radio transceiver for home automation, made to be easily adapted into your own projects. For the reader who has heard about the Tellstick, this is much like it - just with a lot of extra features!


The MultiTRX was sold for a while, but is no longer being produced

Features

  • Control remote power switches from Nexa (only self-learning), GAO and Waveman
  • Decode remote controls from Nexa (only self-learning) and GAO
  • Decode wireless temperature and humidity sensors from Esic
  • Decode Doro Secur alarm sensors
  • Firmware upgradeability through USB makes it possible to easily add new features
  • Advanced custom made protocol with variable packet length, repeating (hops can be set) etc.
  • Settings can easily be viewed and set
  • Communication is made easy: Once connected, the MultiTRX appears as a serial port (FTDI VCP-chip)
  • Works right out of the box with Linux and Windows
  • Pads for UART TX/RX - can be interfaced directly to your Arduino or other uC-project!
  • Good frequency stability and high quality parts
  • Open source example software with web-UI, Device Control Center, is freely available
