DIY Temperature Monitor Keeping Cables Straight

I have been working on monitoring grain temperature using the Arduino MKR family and DS18B20 sensors, and it worked well the first year but this year the cables I made got drawn over to one side and now it does not give an accurate reading.

I am guessing this is because it is too far to the side that the grain is not insulating enough to keep a steady reading.

What would be the best way to keep them straight?

Extra Information:
I have a Hackaday page for this project here: Bin Temperature Monitoring System.

I initially was going to post on this thread, DYI Open Source Arduino bin temp reader project **help**, to share my project and trouble, but the system told me it was an old thread and perhaps I should make a new one.

I'm planning to keep developing this project to the point where one could simply buy a unit, climb to the top of the bin, drop the cable down, stick the controller to the bin (probably being held with a magnet), and then scan a QR code with an app, and be able to monitor the temperature in their bin. I also plan to keep this project completely open source, and probably keep a DIY version with an Arduino an option. All, that is to say, is if anyone is interested in a collaboration that would be great too :).

Now I'm going to go browse this forum. Seems like there is tons of interesting stuff!

as long as you arent taking their exact product and copying it patents are useless. people have done that and the patent still doesnt hold up in court. patents have become a marketing thing in north america cause as soon as you go overseas the companies who manufacture the products will just sell it to less know companies in developing countries.
