AcuRite Wireless Indoor Outdoor Temperature and Humidity Sensor (06002M) , white

Works as described.

I bought a replacement outdoor sensor. My previous one worked for 3 years before malfunctioning. The replacement will not match my indoor sensor temp (even after restarting both units). One of them is off by 2 degrees. 2 degrees is not huge, but Im here for accuracy so Im a little disappointed. In the future, I will try a different brand instead of replacing the sensor again.

I bought this as a replacement for the AcuRite Wireless Sensor I bought over 15yrs ago. It was worth the purchase over buying a whole new weather system. I also bought the cover for it to help keep it out of the elements. Here in Michigan, our weather can go through some extreme changes and sometimes some rough conditions.

Work well, long battery life

My other one wasn’t working right so needed a new one!

Ive never owned anything AcuRite. I dont even own the weather station you usually need to use with this. What I do own are several Raspberry Pis and an RTL_SDR. Getting this to be read couldnt have been easier. I simply installed rtl_433, and ran it. No commandline arguments required. In just a few seconds, it came back with the product identifier (a unique but static number that lets you distinguish one device from another), the temperature in Celsius, the humidity as a percentage, and the status of the battery (just a boolean value for either OK or not). This device sends out updates approximately every 15 seconds (though this varies by a few seconds each time; this is by design, to avoid packet collisions). The accuracy seems fine to me. When I got it, I stuck it beside our nest thermostat, and the temps were spot on. The humidity did read a few points low though, but I only care about the temps, so that doesnt matter to me that much. So far, Ive just been reading the temps manually, but eventually, I plan to write some scripts, or maybe just connect these to Home Assistant, to set up some alarms for when the garage is about to freeze, or for when the freezers are about to unfreeze. So far, Ive only put one in the garage, but Ive ordered a few more to monitor the fridges and freezers. For the price, you really cant go wrong.

It works great

as advertised

The AcuRite temperature sensor is the weak point in their Backyard Weather Max/min Thermometer. I bought a Backyard Weather Max/min Thermometer that worked fine for about a year and then the sensor failed. A neighbor had the same experience. Both our sensors were on north facing walls under porches and so did not get direct sun nor direct rain. But they are used in Florida so are subject to humidity. I could not replace the sensor at my local big box store and so I replaced the whole thermometer. I still have the display in its original packaging as I am using the original in house digital display. The second sensor again worked for about a year but then failed. It still sends signals regularly but it now reports outside temperatures of 150-160F when it is actually 85-90F. Not wanting to purchase yet another full Backyard Weather Max/min Thermometer when I have two in house digital display systems, I turned to Amazon and found I could buy the AcuRite outdoor temperature sensor. Unfortunately, the first sensor I purchased was faulty and did not function! Amazon refunded the purchase price and I bought another sensor--that works! I will come back to this review when the sensor fails. But actually there is no other make of outdoor max/min temperature with wireless connection to an indoor display that I can find as an alternative. I am updating this review immediately, as the new sensor wireless signal is not as powerful as the original ones were. I cannot maintain contact between the outside sensor and the display unit on a dresser near my dining room. I have had to put the display unit on the inside of the wall that that the sensor is hung on. I cannot see it form my kitchen or dining room and so that is not as convenient as it was before. Second update: the sensor appeared to fail after one week and so I took the advice from Rachel at AcuRite Customer Loyalty and called in to them. They took me through all the steps -- taking out batteries and replacing them, including on the display. It turns out my display has developed problems. I still have the second display from the full Backyard Weather Thermometer that I bought a year ago. It is now connected to the sensor and all is working well. My display is back on the cabinet in my diningroom, and reflecting the correct 90F temperature out side and correct 82F inside temperature

This is the second time Ive purchased one of these. The first lasted 2 1/2 years. The temperature is terribly inaccurate. Ive followed the instructions exactly, including fresh new batteries, re pairing it, etc. If this one fails Im going with a different brand.
