I own a small Laundromat in South TX. and was a long time X10 user. I don't want to think of the money I spent on software, hardware, etc. over the years attempting to get a reliable system in place to monitor and control my mag lock doors, open/close signage, HVAC, FL lights, television, security and CCTV. I was finally pushed into replacing X10 when my internet access went away. So I began my research into a replacement. I can't honestly say how I found Insteon and Universal Devices but when I discovered the technology I was immediately impressed by the redundancy and control available with it. I made a few phone calls to clarify what I needed to buy and started with a ISY 994i, added hardware and began to write new programs. I had a few issues and was impressed with the telephone support I received from Darrell. He was patient and an expert at getting things running. So now I have replaced most of the X10 devices that I needed feedback on like the door locks, if my access door is open after hours, and any intrusions in my office. I also have random lighting after hours, water leak detection with notification, scheduled HVAC and television. I will be adding a IP camera in the near future. I will taking my large box of X10 devices to Goodwill and perhaps someone else can use them in their system. I now have peace of mind and confidence that I am informed that my business is opening and closing on time!
