I have a wemos D1 Mini (an ESP8266 chip) which I am trying to connect to a 1-Wire temperature sensor.

enter image description here

However when I plug it in the 5v or ground it seems to power off the device, this happens with or without the data pin connected (lights stop blinking, usb disconnects). When I try this on an uno everything works fine.

I'm guessing somehow the 1-Wire is drawing too much power but I'm not too sure how to fix it (or if it is fixable) as I'm not too experienced with electronics.

I have tried with bigger and smaller pull up resistors (1k, 20K) but neither seemed to work.

Looks like I was doing something really stupid, I had the ground and 5V round the wrong way.
