what is best model for home appliances control?

pls give brief introduction about home applinaces control ,

which model i buy . i already buy xbee series 2 but i know that series 2 not support switch remote at mode .

pls tell me which one i buy or else can do?

for relay operation?

I am sorry but I don’t understand what it is you are looking for. Does your existing appliance function under a specific wireless standard in which you can control it from? If so, what standard is that?

Are you looking at controlling a relay with an IO line or do you want to control a relay with AT commands or some sort of serial data?
