I am thinking of getting some rfxcomm receivers, and a transmitter to do environmental monitoring (temp/humidity), motion sensing, and door/window status. I have a ~3000 ft^2 two story house. How reliable is the hardware? Would I need more than one of each receiver to achieve good coverage?
What exactly would I need to purchase for each objective listed above?
Is there a sensor that actually measures light levels?
