HomeSeer is pretty much the last step in the home automation progression before you drop tens of thousands of dollars on systems like Control4 and Crestron. There are quite a few open source free local automation hub's out there, but I've tried a few of them and I haven't seen any that are as easy to setup and have the plugin support that HomeSeer has. That local control gives you lightning fast response time for functions that some cloud provided hubs like SmartThings and Wink can take a couple seconds at best. The other huge advantage HomeSeer has is security integration. None of the cloud based hubs offer integration with a traditional security system. If you have a current hardwired DSC or GE(or quite a few others) alarm already installed, all you will need is the correct interface hardware to be able to get it to speak to the HomeSeer hub. The two biggest downsides to the HomeSeer hub is price and setup difficulty. You are looking at about 180 bucks for the lowest end Raspberry Pi based hub on the way up to the high end of over $1,000 if you want full serial control and a much faster computer. But this cost can be significantly offset if you already have hardware you can run the controller software on. Overall if you want the most speed and versatility possible in a home automation hub, the buck stops here.
