RTI remote and RFXtrx433E

Hey guys,

Thinking about buying a RFXtrx433E because I have a old waterproof/outdoor RTI remote that operates at 433MHz that I would like to use on my roof terrace.

Has anyone tried to get a RTI product to work with a RFXtrx433E on a Vera Lite? Any ideas if I am likely to succeed before I spend the $100 on a RFXtrx433E?

Best Regards
