Ambient Weather WH51RF Refrigerator Freezer Sensor

Just got this and only been running half a day, but it's managing to transmit through the freezer door, across a 60' workshop, through a steel wall, through 3-4 trees and 600' field, through a trailer wall and to the receiver. This is with a non-lithium medium charged battery at -17F. Pretty sure you don't need to be concerned with this not transmitting to your base station effectively.

Great. Dropped several times, and still works. Signal transmits through the fridge, and wall, so I’m happy with it.

I have 4 units around my boat freezers and fridges. It works fine for 2 months, then it just stopped working. When i opened it, the battery was corroded. My only issue so far is that this product usually gets used in hight humidity areas and it doesn’t have any kind of sealing or protection against moisture intrusion. A rubber seal and an o-ring will be an excellent idea. I will try to clean it and put new batteries and hopefully it will work again.

*** 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!

I have this in a deep freeze that is used to store processed meat including venison. I was worried about the signal strength passing through a metal freezer and across the house since freezers can act as a faraday cage. It has a strong signal and works perfectly. Note that I am using Energizer Ultimate Lithium batteries since they work well in freezing temps.I can see the temp on my WS2000 display and can also see the temp as well as historical graphs with the Ambient Weather website/app. I am watching the data and have set it to send me a notification if it reaches a temperature slightly above the highest temperature it hits during routine cycling and defrost.I am sharing my weather data online and have also confirmed that Ambient Weather and Weather Underground do not share data from this sensor online. It does not even show this sensor at all from public view, but I can see it when logged into my AWN dashboard.I am very happy with this purchase! I feel it is well worth the investment since losing a freezer full of food would be many times the cost of this sensor.

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.

Does everything it's supposed to. Very good range. I have the unit inside a metal fridge that inside of a metal walled camper that is approximately 150 to 200 feet from the house. No connection issues at all.

I have tried other freezer sensors/alarms in the past and they all had issues. This one is rock solid, good signal from my freezer in the garage, and battery life is great.
