Replace a RF remote with an arduino with RF transmitter

I've got a RF remote control that I use to control my motorized curtains in my house.

I want to create an Arduino solution that would enable me to control the position of the curtains depending on different input (light sensor, date & time etc.).

The remote control is, when first installed, coupled with the motor part to be able to have multiple remotes near each other, which I guess adds some problems to this project.

Any ideas on where to start to try to simulate the RF signals sent by the remote? I know that it transmits on the 433 MHz band and that it has 3 commands (move left, move right, stop), but that's it.

Any suggestions?

If its a commercial solution you might be able to find some info about it... If not, try to use a scope, or a logic analyzer and maybe just replicate them given its only 3 comands... With arduino you can easy create a min and max lenghth and in between values for what you want to achieve !
