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

5-15-2023: Ive owned this sensor for about a month now. Bottom line: I highly recommend it. Makes for a quick temperature and (calculated - you can find various formulas online) dew point sensor within Home Assistant without any need for a proprietary base station (assuming you have an SDR). Im not sure I could make a DIY T/H sensor myself for a better price given the quality. I put it next to two other sensors from different companies and all three were within 0.2 degF of each other. I have used it outdoors and it tracks the trends as measured by an airport weather station nearby. I generally trust the accuracy. It has so far survived temps as low as 15 degF and as high as 80 degF. So far I dont believe its gotten wet since I have it underneath an awning in the shade. Ill plan on updating this review as I see how it performs this summer and later through the winter. As Im sure others have noted, if you do plan to use this in low temperature applications, use lithium batteries. The refresh rate is good for my needs. Im picking up broadcasts between 15-300 seconds. Which is fairly wide and seems to be dictated by changes in temperature rather than necessarily a regularly timed broadcast. However, that could be due to my SDR not picking it up 100% of the time. Either way, I think this should suit the vast majority of people for indoor or outdoor monitoring. I do plan on buying at least one more as a bathroom temp/humidity sensor with the intention of automating a bathroom fan using humidity readings. If I didnt have ecobee sensors for motion and occupancy, I would probably use these throughout the home at a fraction of the price.

I would think anyone using these devices would understand that accuracy is not going to be perfect. Yes the basic units will read different sometimes right next to each other. So many variables. Simply a tad of shade or for example a piece of rebar under a concrete slab under one sensor but not the other can make a difference. For me the place I work lost a lot of food when a circuit breaker tripped on our ice cream freezers, I now have a 7 sensor system to cover coolers and freezers. Do I really care if the temp is off one or two degrees, not really. I only care to know that the temperature is rising. One alert set for 18F and another at 26F. The 18F is early warning and the 28F says get your but over and see what is happening. Bottom line for personal use do you really need to know if the outside temp is 95 vs 97? If you have a mission critical use for these devices you should probably be spending close to or over $1000 for a system if your business needs to be that precise. Even mechanical wire thermometers side by side can read different. This even includes Taylor food thermometers. For perfect accuracy get something that works with mercury.

It works great

To reduce expenses and to help protect the environment, in early 2021 our household started taking a number of measures to cut our energy consumption. Those measures have proven successful: total 2021 electricity consumption in our single-family, detached home in the US SE was about 8,000 kWh (3,200 of which was for HVAC), compared to about 11,000 kWh annual average in previous years. [UPDATE on 1/1/23: our total electricity consumption in 2022 dropped even further to just 5,500 kWh (1,600 of which was for HVAC) for the year. We have HALVED our electricity consumption. Huge savings. This sensor continues to operate beautifully.] Our HVAC system screen shows us how much energy it uses daily/monthly/annually. It’s a useful monitoring tool. We use three other tools to help us understand our energy usage and provide us insights into steps we could take to save: a plug-in electricity usage monitor and a thermal imager (both discussed below), as well as our AcuRite weather station with two of these add-on sensors. Our AcuRite set-up allows us to monitor temperature and humidity in four places at once: outside, in our living room, in our crawlspace, and in our unfinished attic. Those four readings cycle on the AcuRite screen every couple of seconds, quickly giving us a full overview of things. Thanks to these readings, we have established a smarter, more energy-efficient way of ventilating our crawlspace and keeping humidity low in there. The readings also helped us see that our attic needed additional ventilation in the roof, prompting us to purchase and install a 4 Seasons Solar Powered Polycarbonate Vent, Weatherproof Design, Quietly Cools Up to 500 Sq Ft, 400 CFM: www.amazon.com/gp/product/B01DMSCPJA Here are some other products we purchased at Amazon that we can recommend to those interested in cutting home energy consumption: Kuman KW47-US Electricity Usage Monitor Plug Power Watt Voltage Amps Meter with Digital LCD www.amazon.com/Electricity-Monitor-Voltage-Overload-Protection/dp/B07DPJ3RGB Looking back, we can say that purchasing a Usage Monitor Plug has been one of our wisest and most useful moves, and a very inexpensive one at that. Klein Tools TI250 Rechargeable Thermal Imager: www.amazon.com/gp/product/B089QW8R9S This tool, along with the Usage Monitor Plug, gave us a very good picture of where we were wasting energy. It was thanks to this tool that we realized, for example, that our then uninsulated recessed lights were really problematic, prompting us to purchase the following.

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. Im using several of these to monitor temperatures and humidity in a few places around 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. Its the least-expensive way Ive 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/

Worked perfect!

This product was a replacement for one that stopped working. We had it for a few years and needed a new one. This one is working great.

I bought several of these. They all seem to work fine. Im using a cheap SDR to read them with an RTL433 docker, and feed them to Home Assistant via MQTT. There are times where its not super consistently reading some of them, but there is probably a lot of metal blocking/interfering in some of the locations they were placed. Even the ones in the far backyard, on the other side of a 1/2 acre read successfully every so often. Overrall, Im happy with them.

The original AcuRite weather station sensor stopped working and a whole new weather station was almost $100. Figured I had nothing to lose trying this replacement. Put in batteries (not included), let it sit next to the base station for 30 minutes and all was synched. Works like a charm! Very happy.

This was a replacement for the original wireless sensor Model No. 00592TX that came with an AcuRite Deluxe Weather Center Model No. 01099 which they no longer make. The old unit was working just fine; but was looking rather weather- worn so I decided to replace it. I also ordered AcuRites Solar Radiation Shield sold here on Amazon which offers protection from the sun to give more accurate temperature and humidity readings. It should also provide protection from the rain/snow although its not advertised that way. Its very nice!!!!! (My old sensor always showed warmer temps in the summer by 15 or more degrees compared to other outdoor thermometers I had. So I put new batteries in the new Sensor, snapped into the place for it in the Shield, and hung it outside in the same place. However, no signal bars were showing on the inside display. The manual says maybe it would take 20 minutes to synchronize when the batteries were changed. I waited 30 minutes - still no signal bars. So I took the batteries out of the display and reinstalled them. Now I had signal bars; however, the display unit went into the 14 day learning mode!
