Wemo Mini Smart Plug

As part of my "energy conservation" program, I purchased a couple of Wemo Mini Smart Plugs which allow me to control electronic devices from either my phone or Google Home Mini smart speaker. Now, instead of having to get up and walk 3-4 feet to the appropriate device, I just say "Hey Google, turn on/off the fan or heater". And given the fact that the smart plug works over your home's WIFI network, you can do it from anywhere in the world. You can even schedule when you want lights to be turned on/off so that your home looks occupied.

Update (1/4/2019): When the Wemo plug works, it is great but I have found their service occasionally breaks down and is not as reliable as it should be.
