In the wake of a couple of hackers taking down a Jeep Cherokee, we should really reconsider the whole "internet of things" idea. This isn't to say that it's ever not been a bad idea, just that more and more evidence piles up against the idea of networking everything.
In order for the "internet of things" to not be a major security risk, security holes need to be minimal and quickly patched. Instead, security is often an afterthought, or not even a consideration, and, in combination with the interconnection of important "things" with much less important (but considerably more networked) "things" allows for "hackers" to perform significantly malicious acts, and reduces privacy to a pittance.
Steering, braking, transmission, fridges, house lighting/electricity, etc. So many things that have no good reason for being connected to the internet are networked to kingdom come. The only way to guarantee that no one can hack an important system/equipment is to have an "air gap". That is to say, there is no direct connection between the important equipment and any form of transmitter/receiver. The transmission on the aforementioned Jeep Cherokee would be a lot harder to hack if it wasn't connected to the vehicle's built in wifi.
If it isn't a computer, and it doesn't need to be connected to the internet, disconnect it, if at all possible.
