  1. Excellent for linking Lightwaverf to a raspberry pi 5 Star Review

    Posted by on 28th Nov 2016

    I bought this to enable a Raspberry pi to act as a central point for linking lightwaverf home automation, the internet and my own control options. It is easy to write your programs in python to interface with and control this device. I have needed to buy an alternative antenna ( cheaply available from a number of sources ) to increase the range.

  2. Worked out of the box! 5 Star Review

    Posted by on 6th Nov 2016

    I'm using Domoticz running on Linux.
    I had been using some home-made 'MySensors' sensors and actuators but was having range & reliability problems, so I decided to switch to 433MHz. The RFXtrx433e seemed to be compatible with Domoticz so I decided to give it a try.
    I wasn't disappointed; within a couple of minutes I had plugged in the unit, added it to my Domoticz configuration and was receiving data from my new sensors.
    Super-fast delivery from UK Automation too ... Excellent :-)

  3. Works better than expected 5 Star Review
