This is my take on the setup for Home Automation.
- Raspberry PI 3
- 16GB micro SD card (smaller one would be OK, but this was the only one I had lying around).
- Z-Wave.Me USB Stick
- Home Assistant
The Raspberry PI 3 is located in a cabinet centrally in the house. Right now it connects to the network through WIFI. In case of unexpected reboot (power loss etc.) Home Assistant automatically starts.
