X10 is a cheap, inexpensive, yet reliable way to automate your home. A basic starter kit would include a table top controller and a few lamp modules(for about $45.00). It uses a signal that is sent through your home electrical wiring. All of the modules are addressable. For example, you could put some of those nice candle lights in some of the windows in your house. Plug them into X10 modules. Set all of the modules to the same address. Then sit in your living room and push one button on your table top controller and they all would come on at the same time. /w3tcompact/icons/smile.gif
You can get much more complicated than that, as there are also; appliance modules, outlets, switches, radio frequency wireless controllers, timers and on and on. It really is only limited to your imagination and wallet /w3tcompact/icons/laugh.gif
How does this relate to tractors(I'm bringing it back to the snow and tractor subject now)? You could buy a heavy duty appliance module and hook your engine heater to it and start warming up your engine without leaving your house.
