Indoor Outdoor Thermometer Wireless 4.5 Inch Display Digital Hygrometer

Just received & fully tested (for accuracy) this complete 3+1 outdoor temp/humidity sensor with an indoor temp/humidity in its mini, 4-color base station.Verdict??? I definitely recommend👍🏻.I had the following needs & objectives:*Accurate.*Three (3) Temperature AND Humidity remote sensors.*An always visible, easy to see LCD base station w/ quick referencing temp measurements.*Cheap. Cost was $31 total w/ S&H.Summary:*I got all features I required👍🏻 along with an indoor Temperature / Humidity sensor in the base station w/ 4-colors (green, blue, yellow, & white).*Is a perfect compact size for my desk at 5-6" tall & 3-4" wide overall.*Is easy to see in the day time w/ office lights ON & you can dim 1 additional "level" and/or turn off.*I don't need the particular feature BUT, it's often vital for others; each remote sensor can be set to "alarm" at a particular set degree (F or C), along w/ Max Temps reached.Note:a) Its detachable power cable is ~5` w/ a USB on one end & a mini barrel power connector for its base.b) The color, mini base also takes 3 AAA batteries for backup and/or to use if you lose or don't have power.c) The sensors take 2 AA batteries and come set for wireless channels #1, #2, #3.d) As I mentioned, I tested all four measured temperature values (3 remote sensors & base) and their grouped delta F, after 4 hours, read 73.4⁰, 73.4⁰, 73.2⁰, & 73.3⁰. NOT BAD at all.

I’ve been using this thermometer to monitor the temperature in both my freezer and garage, and it has been working exactly as expected. The wireless sensors provide reliable readings, and it’s convenient to see all temperatures on a single display.The garage temperature can change quite a bit throughout the day, so it’s helpful to keep track of it without having to go outside and check manually. I also use it to make sure my freezer stays at the proper temperature, giving me extra peace of mind.Setup was quick and easy, the display is clear and easy to read, and the sensors have maintained a stable connection. Overall, this is a practical and reliable thermometer system for monitoring multiple locations around the home.

This Thermometer / Hygrometer is working extremely well. I've only had it a week, but it was easy to set up (I had to get batteries) and install.I currently have one remote sensor unit outside, one in the garage and one in the attic/roof space. They are reporting without drama and the base unit is getting the kitchen temperature consistently and reliably. I have the remotes hanging on screws I put into wood in suitable places and they seem to be on very firmly. The central unit is sitting on a counter top with the stand holding it steady, but I will hook it onto a screw into the wall when I get a chance. This will also move it from the kettle, which influences its temperature! I have the central unit plugged into a USB-A charger and it is keeping the display bright and very easily readable (I also have batteries in it in case of a power outage). The remote units are small and not in the way, and the central unit will be easy to place on the wall and out of harm's way.I have had similar units from long ago in my previous house. This is a far nicer unit, was easier to set up, and allowed me to run 3 external problems, plus the central unit, which is really good. I am very happy with this unit and I hope that all I have to do with it over many years is to change the batteries.

Everything works great, super simple to set up. Just put batteries and everything and turn it on and you're ready to go. All three sensors read within .2 degrees of each other which is amazing considering the low cost of this item. The temperature readings seem pretty accurate compared to a few other items I have that read temperatures such as my Nest thermostat and my temperature gun. The indoor temperature is also very accurate compared to my thermostat. The humidity readings seem accurate compared to the weather app on my phone and my Nest thermostat in the house. Since I use my garage for food storage I have one of the sensors out there and it has no problem with signal with the main unit which is about 30 ft away through a steel door and a interior wall. One of the sensors is in my backyard and the other is on my front porch and they also have no problem with signal connection. The only reason for four stars instead of five is the off-axis viewing angle of the display is not good. I have it on a shelf and if I'm sitting on my couch which is about 2 ft lower than the shelf which is about 6 ft away it's almost impossible to read the display as it's very washed out at that angle. But the display is bright on its brightest setting and still readable on the lower setting. The fact that it plugs in to any USB power source is very convenient also. The display is easily readable from 10 to 15 ft away as long as you're not at too much of an angle. Overall I'm pretty happy with this for the price I paid. It's just a simple temperature/humidity sensor which is all I really wanted. The little arrows showing the trims are there, but I don't use them or even pay attention to them so I really can't comment on those. If you're looking for something simple like this that just works and is priced very well, I would recommend it to anyone.

Addendum to original: After posting 2 star rating below, out of the blue I received a full refund offer from the manufacturer followed by a full refund. Mind blown and to be fair, I need to set the record straight if I didn't do a good job below. My only issue is with owning 2 units and having both flipping to the strongest remotes w/o interaction from me. A single unit with 3 remotes works great and the price is right. Temperatures have been accurate (within 1/2 degree) between the 3 remotes and the onboard temp reading. Bottom line, the item is great, however adding a 2nd unit with additional remotes, not so much!BTW, I'm having no issue receiving signals through refrigerator and freezer doors (1 upstairs, 1 downstairs).I'm impressed, only good companies do what this one did in offering an unsolicited refund!Original 2 star review:I have two of these in my home for a total of 6 remotes. Before I purchased them I asked the question:Looking for specific info? "can I use 2 of these with 6 remotes"Alexa is generating a response...Yes, you can use 2 of these with 6 sensors total! Based on the product's own setup guide and community Q&A, here's how:Setup for 2 bases with 6 sensors:Remove all batteries from both base unitsInstall batteries in the first set of 3 sensors (channels 1, 2, 3), then power on base unit 1 — wait 3 minutes to let them pairInstall batteries in the second set of 3 sensors (channels 1, 2, 3), then power on base unit 2 — wait 3 minutesImportant notes:Each base unit only displays its own paired 3 sensorsKeep the two base units separated by some distance to avoid cross-talk between sensors, since all units use the same 3 channelsIf a sensor pairs to the wrong base, you can manually re-pair it using the TX button on the sensor and the CH button on the baseSeveral customers have confirmed this setup works well for monitoring multiple locations like garages, basements, greenhouses, and outdoors.I am constantly having to re-pair these units. They are accurate, signals transmit a long distance, even thru refrigerator doors, but they cross over about every two days. As you can see by the pic, 1 and 3 are exactly the same unit. If only buying 1 unit with 3 remotes, go for it, it's great, but don't do 2 units, you won't be happy.

Good quality accurate readings that are stable and function well. Easy set up. Good size display that is easy to see. Love the backlight functions and appearance. Use with batteries or USB power supply. It's perfect for my needs and I love the 4 zone readings.

Works great. Very glad to have 3 remote temp sensors all displayed with the house temp.

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 periodI 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.

Been up and running for a couple of weeks, inside and outside. Temperatures compared to other thermometers - little difference shown. Unit is compact with clear display, even without the backlight on. Very pleased with this simple product that tells me the temperature inside and out for significantly less cost than other options.

Tengo varios años con el y siguen funcionando muy bien.

​Ich bin absolut begeistert von dieser Funkwetterstation.Das Display ist gestochen scharf, extrem übersichtlich und aus jedem Blickwinkel perfekt ablesbar.Beim Berühren des Sensors an der Oberseite des Gerätes leuchtet das Display für ca.10 Sekunden.Die grafischen Symbole (Smileys und ein Haus um die Innentemperatur und Luftfeuchtigkeit) sind modern und selbsterklärend.​Besonders genial sind die drei Außensensoren:Ich überwache damit die Außentemperatur und die Luftfeuchtigkeit auf der Ost- und auf der Westseite des Hauses und die Werte in meiner Werkstatt.Die Verbindung war im Handumdrehen eingerichtet und läuft absolut stabil ohne lästige Verbindungsabbrüche.Über die Laufzeit der Batterien kann ich noch nichts sagen, alternativ ist ein Kabel für den Netzanschluss der Innenstation dabei.Für den Preis hätte ich für meine alte Station nur "einen" neuen Sensor bekommen.​Für jeden, der präzise Daten und ein schickes Design sucht, eine klare Kaufempfehlung!

Foctionne tres bien

Le produit paraît être de qualité, la mise en route est très simple et avec 3 capteurs, je peux avoir la température et l’hygrométrie en 4 endroits simultanément dans ma maison et mon jardin (attention le capteur extérieur doit être protégé de la pluie). Au niveau fiabilité des mesures, j’ai laissé les 3 capteurs près de la centrale et les données, si elles ne sont pas identiques, sont très proches (voir photo).
