Unless there is a plugin for the CM15 for IR signals then a Marmitek RF10 maybe the one to go for. The RF signal range on these remotes isn't the best.
The Harmony range of remotes are very good. I use one at home, and this does control the lights. But it uses the IR reciever on my Homevision controller which then translates it to an X10 command. Unfortunately the Homevision controller is no longer in production. The Homeseer software might be worth looking into. There are IR to X10 gateways out there, but many of these are limited to 16 or less X10 commands.
Have a look here;
