New RFXCOM USB RFXtrx433 Transceiver Supports LightwaveRF

RFXCOM have announced their new USB 433.92MHz home automation transceiver – the RFXtrx433.  This device has replaced the USB receiver and USB transmitter and has flash memory so that new protocols can be added in the future.

It already supports a few protocols that were not available with the previous RFXCOM, such as Mertik Maxitrol gas fireplace, and a few La Crosse and TFA weather sensors.  But most interest will probably be for the addition of support for the popular LightwaveRF range of modules

“Today we introduce our brand new Home Automation solution the USB RFXtrx433.  The USB RFXtrx433 supports the largest number of 433.92MHz RF Home Automation sensors and actors available on the market. The RFXtrx433 is already supported by many popular Home Automation applications whilst the list is growing rapidly. Application builders benefit from the free of charge Software Development Kit, End-User benefit from flashable product enhancements.

Based on the latest technology we offer a versatile high quality solution against a very affordable price to our Home Automation customers.  The RFXtrx433 supports the same sensors and actors as the current RFXCOM receiver and RFXmitter and in addition: LightwaveRF, Siemens, La Crosse, TFA, Mertik Maxitrol gas fireplaces.”
