I try to use rfxtrx on Home assistant and .i have this error.

Send: 0x0d 0x00 0x00 0x01 0x02 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00

UnboundLocalError: local variable 'data' referenced before assignment

my python version is 3.5.3.

this error append on if not data or data == '\x00': on line 621 on file __init__.py.

the if not not work if there are an exception on try. To fix it localy I have add
data = False before the Try

It seems that you use an old version of pyRFXtrx. This should be fixed in the latest version.
Edit: Added another line to make sure it can not happen again: #69
