I have tried the following
1. revert the mac back to snow leopard which I knew it was working with candelair 1.7 and older remote buddy. However, it did not work. It seems it is firmware related? Does remote buddy / mountain lion perform one-way firmware update?
2. I am able to wake up my mac mini using remote running snow leopard (but not Mt. Lion)
3. I have uninstall and install remote buddy with default Candelair driver (1.22)
4. I ran the RCD and everything is green! But it is still not working! The following is the RCD log
