Remote switch to select between 1-8 coded Remote relays. That can opperate between 5-24v.
Bonus points if they use some sort of 8 digit code, so they dont close the relay if they get interfance.
Extra bonus points if someone is already making these and i am a dufoos that cant find them.
I am looking to do something similar. One thing I found was this http://www.controlanything.com They are relays that connect to your computer via USB, WIFI, Ethernet, or wireless. I am just starting to do some research. I don’t know how you wanted to control them or what your budget is but I hope this helps.
