DS18B20 sensor problem


Thank you for taking the time to submit your bug/issue! Please use the points below as a guide when submitting.

  • Device & model you are using (Ex: Pi 2 Model B or Arduino Uno with W5100 ethernet shield)
  • What dashboard are you using? (Web, iOS, Android)
    web and iOS
  • Please describe the bug / issue as detailed as possible. Attaching the code and any relevant screenshots would be very helpful!

First I am have having trouble with the connection. Several times they show disconnected on the web browser or the temps read either 32 or nothing.

Secondly, the widget don’t stay as I set them up to read as a value and temp icon. Many times they have changed to line graphs(most populated as line graphs which I’ve never encountered before).

I thought perhaps I had wired them incorrectly and searched threads on here dealing with these sensors and it showed wiring only 1 resistor but as I found out there must be a resistor across each sensor or only 1 populates.


can yo post the code you are using.


hey there @shramiksalgaonkar:

I am using Rpi3 so no code. Seems the problem went away.
