I have got a doubt, but I haven't found reply. I would like that someone could tell me the solution of my question. I have got an transmissor RF 433 Mhz connected in my Arduino (pin 10), and a receiver RF 433 Mhz connected in the same Arduino (pin 2).
My sketch is simple, but it works enough ok. I can open two lamps and a electrical appliance with my mobile phone. Until here, no problem.
Is it possible know if my switch RF is ON or OFF when I am not at home?
Sometimes, the signal RF doesn't arrive correctly and I don't know if my electrical appliance is run on or not when I am not at home.
I work with library RC-Switch. Too, I've "read" library "Remote Switch" but I haven't found anything. My know about programming aren't very high.
Is there some sketch or code, that I know real state of my devices. If they are ON or OFF.
Thank you very much!
