Outside temp cotrol

What would be a good outside temp controller for cooling only?

Do you mean something that hooks up to a fridge/freezer? I have an Inkbird, and quite like it. It has outputs for both heating and cooling, which seems to be the default these days. I also have a Ranco controller, which can be set for heating or cooling (but not both in my model), which does pretty well also (those take a little electrical knowledge IIRC – my dad assembled it for me).

Yes, just for cooling. I dont need heating.

Ditto on the Inkbird.
