Looking to add a temperature sensor

I’m looking to add a temperature sensor for my beer fridge. Any suggestions on a good, relatively inexpensive sensor? Thanks.

i have been using the sometimes very cheap visonic sensor in a thick ziplock clear pouch. which the battery will drain down fast due to the cold temp it will last at least a year.

What country are you in and what model hub do you have? The device selection does vary somewhat. :sunglasses:

US… I have the smartthings hub v3
