Hi,
I have TFA temp sensors 30.3249.02 that are not recognized by RFXtrx433E. RFX User manual told that they are supported with LaCrosse protocol.

HW version 1.3. Firmware version 1011. Firmware type Ext.
LaCRosse protocol enabled

Any suggestions?
Thanks a lot

Hi @marcomarco

I suggest, that you upgrade your RFXtrx-433E to the latest version.

Currently

RFXtrx433E Pro1 Firmware.zip 1048 2
RFXtrx433E Pro2 Firmware.zip 1051 2

As far as I know Ext firmware does not support your device and I think you need Pro2 firmware, so version 1051.

Regards
