What to do with my temperature sensors?

With my 3 Multiplusses I have received 3 temperature sensors. What can be done with these so I can make a smart use of them? Suggestions to Connect them to my Cerbo GX for any usefull feature?

I put them on top of the Multiplus, at the air outlet, to measure their temperature. Unfortunately it is displayed as battery temperature, but you have a orientation what temperature they have.

You don’t have to use them. They are a bit of a throwback to the lead battery days when you wanted temp compensation.

I attach them to the heat sink of the solar charge controllers. In the device list, you can give them an appropriate name.
