I am working on a project for basic home automation. I currently have a relay setup into a outlet box and can control whatever is plugged into the outlet via my pc.
My general concern now is that how can I move this wireless.(the connection between the relay and the arduino) Or would I have to have an Arduino unit for each outlet box. This could get expensive.
I currently have:
SPDT Relay and circuitry inside the outlet box. (220V power)
I have though of doing the following:
Control the outlet box with RF : http://www.hobbytronics.co.za/p/28/433mhz-rf-link-kit
Would this be possible and If so , how would I proceed?
