Whit the new RFX-433EMC USB/Wifi/MQTT it is posible to operate the RFX by Wifi.
How can i add it to Domoticz via Wifi ????

Wifi is LAN so you probably can use one the RFX with LAN hardware gateways options. You have to know the IP adress of the RFX device and make sure it is fixed IP by your router.

See the RFX MQTT User Guide chapter 6.2

Install a MQTT broker,
Flash RFX433EMC_MQTT_WiFi in the RFX-433EMC. (chapter 3)
Configure WiFi in the RFX-433EMC (chapter 4.3)
Configure MQTT and the 433 protocols in the RFX-433EMC. (chapter 7)

do not use BlindsT0 as this disables all other protocols.
See the RFX User Guide.pdf

Enable only protocols you need to receive!!
See the RFX User Guide.

Wrong Firmware and Version displaymust be solved in Domoticz but does not produce any functional problem.
