I love ESP8266 devices. I have about a dozen at home for various purposes. They are so small that they can be placed anywhere and consume very little electricity. I download ESP Easy to an IoT device and use it for thermometers, motion sensors, door (reed) switches and relays to turn lights on and off. The possibilities are endless!
