I think HA is great for many reasons but mostly due to the fact that I have a very rare medical condition (Ehlers Danlos Syndrome) where even a minor bump on the leg can leave me without the ability to walk, I have been injured where I can't walk for up to six month long stretches, having the ability to remotely control lights or have them come on based on automation rules is helping me greatly. I started with X-10 back in the late 70's when I first saw it at Sears, I had X-10 it until 2006 when I bought my first Insteon stuff, I briefly switched part of my house to Lutron RadioRA after I had 3 PLC failures in a short amount of time. When I started replacing my incandescent bulbs with energy saving LED bulbs I would either have to spend a fortune on new RadioRA dimmers that would work with smaller loads or switch again so I bought an ISY-99i, a PLM and went back to Insteon in 2010. I just recently replaced my ISY-99i with a ISY-994i ZW/IR Pro and a new PLM so I can replace some of my original dimmers that have failed tact switches, I also bought new remotelinc2 controllers because I got tired of replacing tact switches on the original remotelincs. If not for the ISY, I would never gone back to Insteon, I never had any trouble with my ISY-99i or the PLM I bought in 2010 and hope to get many good years out of my new ISY-994i ZW/IR Pro.
