Review on AcuRite 06044M Wireless Temperature Humidity by James Davis

They work well but only seem to be accurate to +/- 1-2 degrees (using a FLIR infrared thermometer for comparison). It's good enough for my purposes though, it lets me know if something is comfortable or not and gives me a health check if I'm hot or cold to see what it might be. The battery life is not as good as that of the outdoor sensor. since it uses AAA cells instead of AA cells (1 year per set of AAA cells for this indoor model), but having an LCD display for personal reading is very nice and worth the trade-off. You can just ditch the battery case and swap it out by adding an AA holder to the battery contacts if you want to extend battery life and don't care about looks, or use rechargeable batteries and charge them more often. I use about a dozen of these (plus a few outdoor sensors) to monitor temperature and humidity in most rooms in my house with a DIY home automation system. They work great with the RTL-SDR and the free RTL_433 software to decode the sensor readings (just need to figure out which ID which sensor turns them on one by one) and then I use the Hassio Home Assistant to log and graph the readings . I found this to be the most cost effective way to monitor temperature and humidity with long battery life for multiple sensors in a smart home solution.
