Here an overview of the RFXCOM 433MHz transceivers with the main differences.

RFXtrx433

• Released Feb 2012 (support ended)
• This is the first version of the RFXCOM transceivers.
• The RFXCOM microcontroller has 64kB memory, no EEPROM, analogue transceiver, USB mini-B connector.

RFXtrx433E

• Released August 2014 (support ended)
• The RFXCOM microcontroller has 64kB memory, EEPROM (to save protocol settings and Somfy RTS rolling code), analogue transceiver, USB mini-B connector.

RFXtrx433XL

• Released August 2018 (support ended)
• The RFXCOM microcontroller has 128kB memory, EEPROM, analogue transceiver, USB mini-B connector.

RFX433XL

• Released Dec 2022
• The RFXCOM microcontroller has 128kB memory, EEPROM, digital transceiver, USB mini-B connector.

RFX433XL Wifi

• Released Dec 2022
• The RFXCOM microcontroller has 128kB memory, EEPROM, digital transceiver, USB mini-B connector, ESP32 Wifi module.
• RFXCOM protocol decoding is in the RFXCOM microcontroller. Wifi is handled by an ESP32.

RFX-433 USB/Wifi

• Released Jan 2025
• The ESP32-S3 microcontroller has 8MB memory including EEPROM, digital transceiver, USB-C connector.
• RFXCOM protocol decoding and Wifi is handled by the ESP32-S3.
• The RFX-EMC microcontroller is available for the secure protocols (Brel bi-directional, Cherubini, Ozroll)

RFX-433EMC USB/Wifi

• Released Jan 2025
• This is an RFX-433 with the RFX-EMC secure microcontroller.
• The RFX-EMC is used for the secure protocols (Brel bi-directional, Cherubini, Ozroll).

RFXflash version 10.0.0.1 03-01-2023

• Firmware file selection added for RFX433

RFXflash version 10.0.0.0 15-11-2022

• Firmware file selection added for RFXtrxWifi/RFXtrxUSB hw version 3.2

RFXmngr version 19.0.0.40 01-01-2023

• 868 – selection Alecto5500 changed to Fineoffset
• RAIN10 – WH5360,WH5360B,WH40 added
• RFX433,FWtypeRFX433,FWtypeRFX868 added

The new RFXtrxUSB and RFXtrxWifi are available with a 433MHz transceiver or 868MHz transceiver.

The 868MHz transceiver supports the protocols:

• Visonic PowerCode sensors,
• FS20,
• Itho CVE RFT
• Itho CVE ECO RFT,
• Orcon,
• Edisio,
• Alecto ACH2010, WS5500,
• FineOffset WH2900,
• Davis Vantage Vue EU.

The 433MHz transceiver is able to transmit all protocols that can be used by the RFXtrx433XL for example Somfy RTS, Dooya, Chacon, X10 ….
And in addition it can transmit the new Brel and Dooya protocol.
Receive is not yet fully implemented. At the moment X10, ARC, AC are supported for receive. We hope to add additional protocols soon.

A limited number of RFXtrxLAN units is available now.  http://www.rfxcom.com/RFXtrxLAN

The RFXtrxLAN can have the RFXtrx433XL or RFXtrx868XL installed. After testing multiple LAN and WiFi controllers finally we found controllers that do not disturb the receive sensitivity at 433 and 868MHz so that the RFXtrx transceivers performs the best.
The RFXtrx XL transceivers can be placed anywhere in your home or your holiday home or whatever place as long as an Internet connection is available.
It is also possible to access the RFXtrx XL transceivers by multiple applications at the same time.

• Easy to configure, no software installation
• Easy to install the RFXtrx XL
• Maximum RF performance
• Also possible to use for other serial devices (at 3V3 logic level)
