06044M Wireless Temperature and Humidity Monitor Sensor

I am very happy with the AcuRite Temp Humidity Sensor with LCD display. I got this monitor/sensor for my unheated (except by convection up the stairs) upstairs bedroom and an add-on to the sensors connected to my AcuRite hub. This is the model with the LCD display so I can just look at it and know what temp/humidity are in my room. Courtesy of my AcuRite network hub I can check the upstairs temp/humidity on my iPhone along with the outside and other inside sensors that cover my living room, basement and front porch. As a stand-alone unit it's nice and gives results very close to my ThermoPro non-connected temp/humidity display. The LCD display is easy for me to read in most light but a future version might benefit from a backlight button. It really shines for me as part of the AcuRite networked system. The sensor comes with a small paper set of instructions. Batteries not included. I just put in 2 AAA cells and it came on. Within a couple of minutes it was detected by the AcuRite hub and I added it and renamed it to "upstairs". Easy Peasy! This sensor is inexpensive, works well as a in-room display of temp/humidity and is a great add-on to my AcuRite hub/app. Small simple and easy to setup completes the picture of what I see as a 5 star product. I'm very pleased.

I purchased two of these to try out for a home automation project, and ran them side by side for several months. The price is very attractive, and I also wanted something with a large display. It's hard to get individual parts this cheap let alone a packaged sensor unit. But are they reliable? Shortly after I set them up, one unit would work for a week or so and then "lock up". To reset I had to take batteries out, put them back in, and it would work another week or two. Eventually I contacted support for an RMA return and they asked me to confirm the batteries were quality brand. One unit had Duracells, one unit had a cheap generic store brand (totally unintentional, just what I had handy) but I said it was fine, I confirmed the voltage was perfect. So they authorized me to return it for replacement. But first to humor them I swapped batteries between the units -- and WHOA! Now the other unit had issues and the "broken" unit now worked fine! Now that both units have name-brand batteries I've got no issues - and I'm monitoring them very closely via data logging. I cancelled the return. Tech Info: I am using this with a USB SDR receiver dongle on linux running "rtl_433". It works great, and each device has a 4-digit ID code plus channel A/B/C so theoretically you could run a LOT of these if your software supported it. I think you'd run out of 433MHz bandwidth first. It updates every 16 seconds which is over double the rate of other units I've tried. And it repeats the data 6 times in each transmission to *really* ensure it gets received consistently - which is also more than twice as aggressive as other units. I've really got no complaints at all. Pros: - Low Cost - Large Display - Updates every 16 seconds (verified!) - Accurate: Side-by-side my two units stayed within 0.2 degrees and 1-2% humidity of each other, again better than others I've tried Cons: - I mean, it's probably not going to last forever but....?

This is the most accurate remote sensor that I have found. It can work stand-alone, but also works with compatible AcuRite temperature/humidity consoles. Most manufactures can get the temperature pretty close, but relative humidity is much harder, so it's great to see that AcuRite is true to their name. My main complaint is that there is no readout for tenths. This seems to plague the entire AcuRite product line, so it is obviously reflects a design philosophy. And I understand that sensors in this price range can't be accurate into the tenths, but tenths are still useful for monitoring trends. Is it getting warmer? No way to tell until it warms up a full degree. And a minor quibble - the mounting system is pretty weak - a triangular hole in the back. There is no way to adjust the viewing angle, whether wall-mounted or resting on a surface. But to come back around full circle, if one needs reasonably accurate RH information, this one is a cut above most others.

These work well, but they do seem to be only accurate within +/- 1-2 degrees (using a FLIR IR thermometer as a baseline to compare). Good enough for my purposes though, it lets me know if something is probably comfortable or not, and gives me a sanity check if I feel hot/cold to see what it might be. The battery life isn't as good as the outdoor sensor since this uses AAA instead of AA cells (~1 year on a set of AAA's for this indoor model) but having a LCD to read it in person is extremely nice, worth the tradeoff. You could easily ditch the battery door and modify it to add an AA holder affixed to the battery contacts if you wanted longer battery life and didn't care about looks, or go with rechargables and top them off more frequently. I'm using about a dozen of these (plus a few outdoor sensors) to monitor temperatures and humidity in most rooms inside my house in a DIY home automation system. They work great using a RTL-SDR and free RTL_433 software to decode the sensor readings (just have to figure out which ID is which sensor powering them on one by one) and then I use Hassio Home Assistant to log and graph the readings. It's the least-expensive way I've found to have temperature+humidity monitoring with long battery-life of a lot of sensors in a smart-home solution. The RTL-SDR is also on Amazon: https://www.amazon.com/RTL-SDR-Blog-RTL2832U-Software-Defined/dp/B0129EBDS2/

You might not expect very much from this little thermometer when you first see it, after all it looks pretty much like most of those little cheap plastic things that are supposed to tell you the temperature in your room. It actually costs less than many of them so you might simply skip right over it without giving it a second thought. But wait, for about twelve bucks this little gadget is worth consideration, if you happen to have the right AcuRite home weather station components or are planning to get one. I have one of their more deluxe weather stations, although it’s not necessary to have one to consider this sensor. My unit has one of those weathervane sensors that mounts on the roof to monitor rain, wind, temperature – actually five different things, which is why it’s called a 5-in-1 weather station. The indoor display shows you all that and keeps a record of the maximum, minimum and trends over time. What’s especially nice about the unit I have that it works with their app so I can check everything I mentioned and more on my phone or tablet device, not only from home but from anywhere in the world. I can even have it email me or text me an alert so it gives me extra security of knowing about temperature extremes that could cause pipes to freeze or even if the room is suddenly getting too hot, like in a fire. I can even add sensors for the freezer, swimming pool, fish tank and all kinds of other things that could be subject to temperature extremes. What this device does is gives me extra temperature and humidity readings for different rooms, like maybe the attic or storage shed. There are two different versions of it, one is just a sensor and the other is this one that adds a digital display. They are both priced the same so my logic is why not get the one that also gives me a remote readout as well as just being a sensor. I don’t know how they can afford to sell this thing with built in wireless connectivity to your weather station and phone app for only twelve bucks. Here’s something they don’t directly say but if you dig deep enough you can find some background information about it. The temperature and humidity sensors built in to AcuRite weather stations don’t last forever, after time they will start giving you strange results and keep telling you that they lost their signal or that the batteries are dead even if they are fresh. There is a replacement module that sells for something like four bucks for the rooftop unit but the one built in to the indoor readout can’t be replaced. Well, that’s not 100% true, what you can do is disable it in software and add one of these little remote sensors to replace it and the app won’t know the difference. So for a few bucks getting this thing essentially bought me a whole new weather stations.

Disappointed fresh new batteries installed temperature reading were 6 degrees higher the other devices in the same spot. Could not connect to other device. Nice build finish display but should have a stand or kick out leg to stand the unit

I'm impressed with the AcuRite 06044M wireless 433 MHz temperature humidity monitoring sensor. I was trouble shooting an electric LG clothes dryer exhaust venting issue and wanted to know the temperature in the output duct so I placed this sensor inside the duct and it kept on transmitting data back to the console. At first I had a problem discussed below. I expected the sensor to freak out, but it didn't. With the dryer set to normal, the highest temperature the sensor transmitted to the base console was 141°F. That's hot for a room sensor and this is one of the few that can do it. The next test was to repeat the test cycle with the dryer exhaust venting directly into the room. This time I could see the display of the unit by looking into the dryer exhaust duct where I had placed it. The base station doesn't have a humidity display. The temperature tended to stay around 125°F but did eventually get up to 136°F. The biggest surprise was the how low the humidity was. I was getting 8% humidity at the end of the cycle. House humidity is around 36% - 50% in March 2018 Indianapolis. I then did a comparison test using the house 100,000- BTU natural gas condensing furnace with the sensor in the output plenum. The house furnace after quite a few minutes would be putting out air at 130°-140°F at 4% humidity. Both the house furnace and clothe dryer have similar air sources and hence the same humidity for their working air. Problem: I found it was almost impossible to handle the sensor without bumping the rear Channel A, B, C, and C° - F° buttons causing the unit to change settings. The buttons actually stick out from the case. When I had the sensor in a dryer duct at first it did not connect to the base station and I decided to give up on the project thinking the sensor was probably dead. I started putting things away. When I got to the sensor, I really scrutinized it trying to see if there was anything obvious that might have caused the problem, then I noticed the channel had been switched from "B" to "C". When I changed it back to channel "B" everything started working great! I eventually disabled the buttons on the back of the sensor for Channel A, B, C, and C° - F°setting by removing the conducting actuators. I stored them in the sensor for safe keeping. The buttons now have a space in them allowing them to rattle. That is actually good because I'll remember the buttons have been intentionally disconnected. You could also probably just put a piece of tape over the circuit board contacts for the buttons leaving everything else intact. What would be nice additions? Jack to allow external temp. humidity pressure probe. It could replace the internal sensors when plugged in. A mini phono plug with lots of conducting rings appears popular got this function. The external probe jack would probably be a low cost addition. Other things like time-date calendar functions and data logging would nice, but not if they increase the selling price significantly. This is a robust relatively high precision full scale RF 433 MHz wireless temperature humidity monitoring sensor for not much money. If it got down to $5 I'd put them everywhere.

Overall these work ok, but the price was $16 in 8/2022, how can they justify a 218% increase to $35 in 11/2023, that's way beyond inflation, disgusting greed. I have 5 and they all show slightly different temperature & humidity even when they've been sitting next to each other for 8 hours. When the battery is low, there's no warning they just stop sending updates to the base station.

Muy fácil de usar y te indica con flechas la tendencia de ma temp y humedad

Sleek design and easy to read. Fits in the smallest space. Let’s you know when the humidity level is too high.

This AcuRite temperature and humidity sensor functions as described and is accurate when compared with a digital thermostat and other thermometer. The two arrows that indicate average changes in humidity and temperatures are actually very useful in determining what schedule to put your digital thermostat or humidifier on to maintain a more consistent room comfort level. The Low, OK, and High humidity level indicators on the house in the middle are useful for adjusting the relative humidity to a comfortable humidity level for the current temperature. Overall, very happy with the performance of this sensor.

Este sensor es pequeño, liviano y simple de usar, pero a partir del segundo día comenzó a dar una lectura estática e incorrecta. De acuerdo con la información, el producto puede actuar como un indicador independiente de temperatura y humedad. Al parecer no es así y requiere vincularse con un dispositivo adicional, el cual tiene un precio igual de elevado y quién sabe si con eso realmente funcione. El proceso de devolución y reembolso fue exitoso.

In the end this appears to be working properly but took longer than it should have to set up. The instructions for setting up the base station do not mention anywhere that a temperature sensor needs to be on first. We tried calling for help on the # provided (which is not toll free) and was put on hold for about 10 minutes before we were given the option to leave a call back # to hold our place in line. It has been 2 days now and still no call back. Luckily we finally put batteries in the thermometer and the base station finally connected to the app. The app now appears to be reporting everything properly but needs better set up instructions and much better phone support.
