I think that wireless control over wifi using esp8266 is very very easy. Way easier than 433mhz radios, which offer a flaky connection and require a perfectly designed antenna to work.
My advice is don't waste your time with rf radio.
The esp8266 supports mesh networks so you don't even need a router. There are tons of examples online, search "fastled websever" on google and you can get a working project set up in about ten minutes. Controlled by your phone.
