LightwaveRF Devices do not turn off with VERA and RFX

Question

I'm using VERA + RFXtrx433E to control LightwaveRF devices, but the dimmers will not turn off.

Answer

This has been identified as a minor bug in the RFX firmware (v225), it is corrected in the later v.227 (or later) firmware. Some units that we've shipped through summer 2014 had this firmware version.

You can check your firmware version in the RFXmgr software from the RFXcom website (see below).
