Technology has come a long way from the early days of home automation 25+ years ago. Back then people were no different than they are today; eager to go with a new idea that will save money. In the early days, energy management was done by brute force, cobbling together wiring, a switch and two thermostats to give the homeowner options and control. Imagine two rotary dial thermostats side-by-side on the wall, one thermostat for energy savings called “Economy Mode” and the other thermostat called “Comfort Mode.” The user would set the desired temperature level for each mode and switch between the two modes by the manual push of a button. Now comes the automation: to remotely switch between the two thermostats, “Economy” or “Comfort” mode, a contact relay was used.
