I use Home Assistant (https://home-assistant.io/ https://home-assistant.io/). They have a "Cloud" option, however, you're definitely able to use it entirely locally depending on what kind of hardware and functionality you want to utilize. Using Z-Wave hardware for your locks, lights, plugs, etc eliminate the need for internet / cloud based connectivity. I have some Z-Wave sensors and such, however, all my lights for the most part are LIFX which use Wifi and synchronize via the LIFX cloud. If you're interested in checking out Home Assistant here's my public portion of my configuration files and such https://github.com/brianjking/homeassistant-config https://github.com/brianjking/homeassistant-config Thanks and good luck!
