Questions to ask yourself...
⚫  How can a company be worth billions of dollars... Yet the services they offer are free?
⚫  Why should I worry... I don't have anything to hide.

 Smart Home

My Smart Home consists of a Raspberry Pi (Model B) 3 running Mosquitto as the MQTT Broker and Node RED for automation. I use the WeMos D1 Mini for all my devices due to its numerous shields, breadboard compatibility, low cost and inbuild USB interface. Not to mention I'm a big fan of the esp8266.
