But... but... there's always someone in a supermarket! It's not like having a manager, who's already there, doing temperature checks a few times a day will cost much.

Sigh.

And if it's for monitoring when the shop is closed, it could be read only!

When it's set for the required temperature, no one needs to change it, unless you change the stuff inside it, which is a big operation in itself and doesn't happen often.

Even the productivity reason doesn't hold.
