ORIAIndoor Outdoor Thermometer, Digital Hygrometer Thermometer, Wireless Temperature and Humidity Gauge Monitor with 3 Sensors, LCD Backlight for Home, Office, Bedroom, White

Received shipment on time based on Prime membership. Shipment was packed well and was easy to unpack. I installed nine AAA batteries (which I provided) into the display unit and three sensors. The sensor temps failed to display. I reinstalled the batteries and still couldn't get the displays to work. Instructions were provided so I finally read them and learned that batteries must be installed in the sensors before the main display unit. That worked. With the sensors sitting together the readouts were within less than a degree of one another. Updates are fairly slow, as they are with a regular thermometer, so don't expect instantaneous changes, such as you might expect with a grill thermometer, for example. I put one sensor in our kitchen refrigerator, another in the same refrigerator's freezer, and the third in our main freezer a floor below. All temps read well and consistently so far, using Duracell alkaline batteries. The sensors are each labeled 1, 2 or 3, respectively, and they do match the displays numbered accordingly, so there was no confusion about placing the sensors where I needed them to be to achieve the order of readouts I wanted.. The sensors are physically small so they don't use much space, and the display unit is easy enough to read.. With only about 24 hours of use there appears to be no issue with the cold environments and metal enclosures. Assuming the unit continues to work well, I would consider this to be a good value, with the absence of batteries being a notable exception..

I have some dampness moisture issues in my crawlspace. I want to determined humidity there compared with the exterior in the hopes of reducing humidity and moisture content. I am soon getting a hot tub and I will be interested in keeping up with temperatures inside that unit housing. Setting up took a little trial and error and rereading of the leaflet that came with it and on line info in the product listing. The main unit and 3 remotes all read within a degree and a humidity percentage or so when placed side by side. They all registered within 10 minutes or less. Response time is fine for my needs. In keeping up with humidity in my crawlspaces and exterior I hope to determine when to open and close my foundation vents or whether I need to take steps toward a sealed crawlspace. The main unit is actually smaller than I expected but still very readable on my laundry room wall. 4 sets of readings... the main unit in that room and remotes 1,2,3. Battery life not determined yet. This was about the first time I remember betting an item like this with not batteries supplied and I needed 9. There is no naming of unit locations, just labeled 1,2,3. Currently located with 1 on the front porch and 2 and 3 in order of location front to back. Of course there is no digital recording of readings. I am pleasantly surprised. Only negative is that the remote cases are a little tricky to open and close for battery replacement or polarity change as I got one battery in backwards.6 month update.... still working as intended. I have not had to replace any batteries yet. It is keeping up with the sensor remotes. Very accurate where I have another thermometer giving info on the same location. One remote is placed in my hot tub frame and giving me temperature and humidity there too.

I keep the main unit next to my thermostat, and it is totally accurate. I've placed one unit in my basement, one in my water pump shed, and one outdoors out of the sun. And it doesn't gobble up batteries like my previous one did. Great product! By the way, I've had this item for three years.

love the fact that i can monitor 4 spots with one main screen. WISH it was Bluetooth, but otherwise works great.. It does take a moment for it to register changes, but not too long. maybe 30 seconds?

I had my first set for five years and it's still going fine. I added to it. I can see my living room temp along with the front porch, back deck and side garden. It's helped a ton with all my plants in my microclimes up here at 6000 feet. Totally recommend it.

To keep tabs on sensitive crops during cold periods, you need this product.The winter of 2023 in SoCal has been crazy. Long periods of record low temps and even snow in extremely low elevations.We have recently planted Avocado trees and Mango trees that need protection and these have come in handy.I can see the spots in the yard where the temperatures are cooler. I can see when temps dip down low enough to warrant frost covers etc.I am using rechargeable batteries in both the main monitor and the sensors. The batteries have going strong for over a month with no obvious signs of drainage. So they should last for months with no issues.The main display is easy to read and had the zones clearly dived into the three different zones. The sensors are super easy to add to the main display bu simply toggling through the proper sensor number the holding it down. When the wireless signals flashes, its connected.Additionally, like that I see the temperate and humidity level.This is a 5-star item and is highly recommended.

I bought an older home with a basement and noticed that it was pretty hot in our house during the summer. I bought these to monitor things. They work great and the batteries I used have lasted well over a year. I put on in the attic, one in the basement, and one in the garage. The attic one actually maxed out over 145F! I put up solar panels on one side of the roof and this summer we saw a high of 135.
