Ambient Weather WH51RF Refrigerator Freezer Sensor

Worked perfect with my Ambient 2902-c. Set the channel and added it with no issues. Use it in a upright freezer on a different level, no issues.

I purchased two of these for an older refrigerator/freezer unit to make sure the thing doesn't shut off or malfunction and waste hundreds of dollars worth of groceries and have yet to have an issue with either of them. Easily connected to my Ambient Weather ws-2000 wx. station, allowing me to see the exact internal temperatures on my app at any time. No issues whatsoever working from within the refrigerator with no wires, transmitting data to the receiver on the opposite side of the house. I used a thermometer to ensure accuracy & they were accurate to with 0.2°F.

*** Update 9/9/24. We have had a couple of incidents where we thought the freezer was closed. It LOOKED closed. But it wasn’t completely. Today I got an alert the freezer temperature was at a certain point I set the alert up for. I had just been in it getting something for dinner. Went back down, sure enough it LOOKED closed, but it wasn’t. So happy I got these! So far at the time of this review, I’m impressed. It’s been working for about 9-10 days and I like what I see. My console is currently on the 3rd floor, and the sensor is in a standup freezer located on the first floor and no connection problems whatever. I bought it because recently we had a problem with a power surge that took out our Verizon box, and our freezer was on the same outlet. We had no idea the freezer was down (although we saw pretty quickly the internet was down! LOL). Luckily we caught it and ran an extension cord to the freezer since the outlet was blown from the surge. Based on the readings, I can even tell when someone opens the freezer to get something out! I’m buying two more sensors for my refrigerator and freezer in the kitchen!

Works, just that simple.

This is a nice Refrigerator Freezer Sensor and works as expected. I purchased (2) of the, one for my refrigerator freezer in the house, and one for my chest freezer in the garage. Both setup and were detected right away as soon as I added the batteries. I was pleasantly surprised that they were detected inside the freezer, especially the chest freezer in the garage. Nice sensor at a reasonable price.
