    We received the Unni Indoor Outdoor unit. We were initially having trouble getting it to work. I reached out to the company, they were AMAZING! First they troubleshooted with me to make sure I was doing what I needed correctly. When we were still having trouble, they sent out a new unit! I was impressed. We received the new unit and it worked perfectly. Once we had it a day or two to acclimate (at least that’s what I thought we should do). It worked perfectly. We put the outside unit in our screen room. It is pretty accurate, maybe a degree or two off at times. But who is perfect?! We live in the north and had snow recently. It was pretty accurate!
    I love the fact that the indoor unit is easy to see and even shows you what the indoor temp is! That’s a plus for me.
    It tells you when you need a new battery too! Love this. No need to go outside!! I believe this is definitely a must buy, totally worth the money.

    5.0 out of 5 stars Fairly accurate temperature & humidity readings, better than other brand name product that cost more
    Reviewed in the United States on October 26, 2024
    I was using a more expansive ThermPro unit before buying this for the 2nd story bedroom. I found this unit is better than the ThermPro in the INDOOR humidity reading while the Outdoor humidity and both indoor and outdoor temperature readings are consistent between them.

    First I compare both indoor and outdoor temperature and humidity readings with both the Head unit and Outdoor sensor sitting side by side inside the house. The temperature readings are within 0.5F while the humidity are within 10% - eg Outdoor is 44% while indoor is 40%. This is significantly better than the ThermPro unit where the difference between indoor and outdoor readings could be as high as 100% e.g. Outdoor is 35% while indoor is 17%.

    The next test is to place both outdoor units outside the house and under the eve, both units gave the similar temperature and humidity readings and these readings are very close to what the online Microsoft Weather page showed.

    Accuracy aside, I found the display is very easy to read, big fonts and good contrast. It also has a backlit button for night reading if necessary.

    The only minor issue is with the Weather prediction feature which is not very accurate. I live in southern California where rain is a luxury to have and this unit had predicted rain for the entire week since I had it and not once rain or even drizzle ever came. This to me is not a show stopper as I only care about the temperature reading more than anything else.

    Just wanted an outdoor temperature reading to determine how to bundle up an elderly relative that I am caretaker for. This device fits the bill nicely. It was easy to set up and install. The hardest part was figuring out where to put the outside monitor. The base module linked quickly with the monitor (about 75' away) and has had a strong connection since. The data seems to be accurate though the humidity slightly differs than another device I have (don't know which is more correct).

    I ordered two of these units and have 2 base stations connected to a single outdoor monitor. Works like a charm. I haven't used these long enough to comment on battery life though.

    I only have 2 small gripes. First, I wish it had the option of displaying outdoor humidity in addition to dewpoint. Second, I wish the build-in stand would let the unit lean back a bit more. As it is, the display sits almost directly vertical on my desk. A magnet on the back would also be nice to stick it to the fridge.

    All-in-all, I am quite happy with this purchase.

    It appears to be well made and sturdy. The sensor is much sturdier than others I've used in the past. I hung mine on a nail and it hangs flat against the wall nicely. The casing at the point of contact with the nail is 5/8" deep so I have no concerns about it breaking there. My first location of the sensor eventually became drenched in late afternoon/early evening sunshine and the temperature sensed was most definitely affected by this, but that's not a bad thing really as it showed me that the sensor is sensitive enough to register the sunshines effect. I did relocate the sensor though as I want an accurate air temperature reading without the suns effect. The accuracy seems to be good. Compared to other thermometers I have around the house it consistently measure +/- 2°. I've also compared it's reading to the NWS published temperatures for my location and again it stays within the +/-2° sometimes 3° range. Very acceptable to me. The display unit is also sturdy and well made. It displays both indoor and outdoor temps and keeps the min and max for the day. I set mine to display heat index but dew point and a mold indicator are also available. The backlight button is easily accessible and is at the point of contact from where the unit hangs so I'm not constantly knocking the thing off the wall. Excellent design there I would say. The display unit is heavy enough that it hangs well and probably wouldn't be easy to brush off the screw or nail it hangs from if you had it in a location that that could happen. It also has a pull out stand on the back for setting it on a table or any flat surface, which also seems to work well. I had no problems with the instructions and had the batteries inserted and the settings set within just a few minutes. Quite easy actually. I like this thermometer and am very pleased with it. I can't speak to power usage and battery drain at this point as I've only had it for a short time, but I might add that information after I've used it for a bit. Overall I'm very happy with my purchase.

    I am thrilled that this thermometer works so well. Rather easy to install and seems accurate.
    I am mostly interested in seeing the outdoor temp, but it is nice to see that the indoor temp corresponds with my thermostate.

    This is a decent size that has a large display that is easy to read. We like the information available on the display. We bought the blue one which is a nice change from the standard white or black.
    We just received it this week so we don’t know how durable it is but first impression is great! Easy to use. Would recommend!
