At home, we have been connecting the garden, lights, doors, the TV, air conditioner, and even Higgs, our pet rabbit, but this last thing will be another post. We have a large variety of devices and sensors, with several Raspberry Pi 2 among them, connected to the WiFi network. Many times we have had to manually reboot the Raspis after a network connection outage because it looks like dhcpcd does not manage this situation.
