  1. Good product, versatile

    Posted by Laurent on 28th Aug 2014

    Great product, versatile.
    I control LightWwaveRF switches, HomeEasy EU sockets, and receive temperature/humidity from Cresta sensors. All managed via DomotiGa.

    Only thing to bear in mind, the more protocols you enable, the more lag / delays you get.
    Range also seem short, but that could be due to interferences from WiFi Router / Dect Phone / etc.

    Customer Support from RFXCom.com is also responsive

  2. range not good

    Posted by John on 15th Jan 2014

    I have two of these at different locations. wing to lack of range, I have stopped using the one in my house for X10 and have gone back to the W800RF32. It still works very well with my temperature sensors though.
    I am using a second one remotely via a Belkin ethernet to USB hub. This keeps going down. As an electronics engineer, I prefer the simplicity of RS232 devices where high reliability is concerned.

  3. Works with my domoticz software

    Posted by Hans on 28th Jul 2013

    I can attached it to my Syno DS209 and installed Domoticz. Works like a charm.

  4. Wow!

    Posted by Mike on 4th Mar 2013

    This device is absolutely excellent! Within 5 mins of plugging in the transceiver I have control of lighting, my central heating and a couple of sockets (all home easy).

    No range issues what so ever, but my house isn't that large and I am controlling nothing within the garden yet!

    I have used the open source Domoticz software so far and that is also absolutely excellent.
