Ambient WeatherWH51RF Refrigerator Freezer Sensor

*** 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 was skeptical that I would get enough signal through the metal doors on my refrigerator/freezer, but I was proven wrong. I installed this in our vacation home and have been able to monitor it without fail. I have noted that the frost-free function of the freezer turns on every couple of days and the monitor notes that the inside temperature reaches 33º every few days for a short period of time, just enough to melt any frost, I guess. Overall, I'm very happy with it and bought another for my home freezer for when I'm away at the vacation home.

Perfect!

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.

Bought one of these so we could see our freezer temperature on our venerable WS0265-3000. For some reason, it took about a day to begin transmitting, but then was fine. We have thought the gasket on the freezer might not be kept keeping the temperature lower up, but it turned out to be fine. So we bought another sensor for the refrigerator. It’s working great too
