Our home has an ABB home automation system. We use it to control all our geysers, lights and fans(but not fan speed) through IR remotes in the bedrooms, and a central control panel in the living room. It can also be used to control your A/C's and other electrical outlets. We haven't opted for internet connectivity, but if you do, then you can control your entire house via an app. It's a bit pricey, but it works, is trouble free, and the company is big and old enough that it won't go out of business and render all your internet connected devices useless.
Our system is more than 10 years old, and probably outdated. You should contact them and see what they have on offer now.
