I recently bought this one on Amazon due to losing about 50 pounds of venison sausage in my deep freeze that quit. https://www.amazon.com/dp/B09BVLP9C5?ref=ppx_pop_mob_ap_share I have tested the alarms on wifi and Bluetooth and they work great. Comes with 3 sensors so now my main fridge, garage fridge, and deep freeze all have sensors in them.

If you just want bluetooth…

If you want wifi and plan on having a bunch of tupperdors this is a good value. You can add up to 10 devices on a network.
