Review: Highly Recommended! - Excellent choice! This thermometer is by far one of the best we have ever used. We have one in our greenhouse and both shops. The temps are clearly shown and spot on. The only downside is that it is not wireless, so we can't check them from our phones. HOWEVER, it is great to be able to get up in the middle of the night, check on the greenhouse, and not have to go out there in the cold to see if the heater is still working. If you want a great thermometer that is accurate and can track multiple locations, this is the one for you. Highly recommend and would purchase it again if needed. Oh, and one more thing, the ease of set-up is amazing. It works exactly like it should and if it does go offline, it is super easy to synch back to the main display.
Review: 3 Yrs Accurate, consistent readings - If you'd rather not read my glowing review, here is the short of it: For anyone shopping for an *economical*, *reliable*, wireless, multi location temp / RH% setup, stop shopping. Saving 5 or 10 bucks once you unpack it, Read the instructions, place the remotes, evaluate the readings and, then, possibly discover shortcomings that warrant you're having to return it - well, it's just not worth it. Save the money and the headache. Buy this unni. You'll be happy with it and you won't have to look back, wondering if you would have been better off purchasing this or another unit. Now for the specifics of my experience with this unit: This unni four location sensor set is the best of 3 I purchased in a 10-year period I purchased this product in July of 2023 and have replaced only one of the batteries in one of the 4 units (The configuration I purchased was one base unit along with three remote sensors) All 4 of the units in this kit have provided very accurate readings consistently when placed in same location (to ensure that they read the same in the same environment). The base remains in the same spot and has been consistent in readings for almost 3 years. Each of the remote units, I have intentionally rotated interchangeably in their respective locations and all have been accurate to within one degree and 1% RH. Over approximately 10 years, I've purchased at least six different sets of hygrometers (with three of the sets being good and accurate) and have rotated those sensors to compare with these and have found all measurements to be close to identical. The two other remote kits from semiexpensive and well-known manufacturers were garbage by comparison and other the multi-unit sets of non-remote sensors, while accurate, did not provide the convenience of a centralized dashboard. I highly recommend this "unni" branded multi location wireless thermometer/hygrometer far above the other two unjustifiably expensive, big brand name multi-sensor kits. This unni branded set is super economical considering the remote readability from the centralized base and the extremely efficient consumption of battery power. The base console / display, from which the local and remote conditions are observed, is powered primarily by the wall adapter and only uses battery power in the event that electricity from the receptacle is not available. Evaluating this kit from cost : features and performance ratio, it's a no-brainer winner. Excellent value excellent performance for almost 3 years in service.

### ⭐⭐⭐⭐⭐ Handy Product with GREAT CUSTOMER SERVICE
*by F***Y on March 27, 2026*

This model transmits the 3 temperatures & humidity readings from our RV conveniently to the house, plus giving a temp and humidity reading for the room where the monitor is located. I use one transmitter in the RV refrigerator when getting ready for a trip. I know if the food is in a safe temperature zone... no quess work. We also monitor the portable dehumidifier in the RV by the humidity readings. This tells us when the dehumidifier is full and needs emptying. thus preventing the RV from getting moldy & musty. Thank you U Unni for quickly answering our questions and replacing a transmitter when it failed.
