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....?

They work, easily connect to my rtl433 setup. I did not realize that these do NOT come with batteries in the package.

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/

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

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.

Works great and if you want a visial readout this is the obvious choice. However compared to the models in the picture this thing eats batteries and twice the rate at least. I live in Yukon and have the model in the attached pic outside year round and batteries last most of a year. This one is in the bedroom and they only last a couple of months at best. If you are going to use the app anyway, I would go with the other model

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.
