Node MCU With Three DS18B20

This is a project I made for weekend house, which is small but on two floors. It is quite unhandy to go up and down just to see temperature in every room, so I had to do something. So this project is result of my pure lazyness :-) Two indoor sensors and one outside, with LCD for read out and WiFi access point and HTTP output for read out when I’m on “wrong” floor.”
