One wire 31850k errors

I have been successfully getting temperature data for 11 sensors until recently I get for only three. I don't know what could be the problem since I haven't changed the code..Someone kindly advise. I have been updating the libraries and I suspect that but I don't know how to troubleshoot it...I am using the external power on the breadboad with arduino mega.

Hi, @surahsign
Welcome to the forum.

Please read the post at the start of any forum , entitled "How to use this Forum".

This will help with advice on how to present your code and problems.

Can you please post your code and a circuit diagram?
What model Arduino are you using?
How are you powering your project?

Thanks.. Tom.. :smiley: :+1: :coffee: :australia:

Hello. If you want you can check if it is really from the new library by trying to replace it with the previous one you used - Arduino IDE allows you to choose a version of the library. Good luck.
