    Yes you're right but it's not the same technology. TV remote are IR. Power outlets are RF (433MHz). To allow to control everything from your TV remote, you must add IR sensor to get TV remote codes (You can read my other tuto: Tuto 2: How to control RGB LED strip with IR remote ? on my github https://github.com/ibenot/Arduino) It's working with my Samsung TV, Sony speaker, LED Strip remote.... After, you must add 433MHz transmitter to send an action to a specific power outlet. For example, when I press "A" button from my Samsung remote, my arduino IR receiver get the code and execute specific code in my sketch to send a 433MHz signal to my outlet #2. I could write a tuto if necessary ;)
