With current technology, one thing that can be done is to control the temperature in your home or office from your smart phone. There are several manufacturers that have the capability with their equipment or with your existing equipment. Your existing system can be modified with this new technology as it does not require a complete system replacement. This technology is something that would work well for someone who is not in their home all the time or someone who is just interested in the monitoring home temperature. Technology makes things pretty easy; you don’t even have to get out of your chair while watching TV to change the temperature. You just take the phone out of your pocket to change it.
