Are there any affordable temp monitors for a fridge that have historical data or just an indicator that the temp was warmer than a set value?

We'd like to start leaving condiments at our houseboat - it has a smallish 120v fridge/freezer. Up to this point we've brought everything home each trip incase it loses power etc. I'd like to not haul all that stuff home every time and have been trying to find something that can easily show us if the temp exceeded say - 45 degrees so we know to toss all of that stuff. It is a combo unit so does have an upper freezer - I was thinking low tech and just the old coin on top of a glass of ice, but that doesn't directly tell me if the fridge temp was warm.

It doesn't have to be digital - even an analog 'max temp' gauge would do the trick. I don't need wifi/cellular (although there is sort of wifi at the marina).

Thanks.

There's this guy:

If you need remote with an app, you could try this device:

Awesome - exactly what I was looking for and for whatever reason it never came up in my search results. Thank you!

We bought this one the summer of 2019 for a garage freezer. Cheap. Works great. There is a switch so it works for either fridge or freezer temps.

I have a couple of these.

Bought two Accurites, one for the garage and one for the kitchen.

Similar to stoic-1's second link, there's this unit from Mocreo.

I have a set and am impressed so far.

I swear by their stuff.
