Building a Home Automation Pi

So, I've been playing around with the Raspberry Pi and home automation devices such as IKEA Trådfri lights, a TP-Link HS100 switch, my Netatmo smart thermostat and a few ESP8366 devices including various varieties of Sonoff switches. Rather than blunder on I thought it would be nice and take stock

VPN

The UK Digital Economy Act of 2017 brings into force the strong possibility that the UK government will introduce age verification to certain websites (i.e. porn). This, in itself, is worrying and something I strongly disagree with. Sadly the genie is out of the bottle with internet content. If
