OUR PRODUCT FAMILY KELVIN Nightlight/Monitor MELLA Sleep Trainer Clock WISPI Humidifier Diffuser Learn to Tell Time Clock Reward Chart Bundle Review: Great product and amazing customer service - The cutest and one of the most useful little thing in my son's nursery. The size is perfect, the colors are great and works great as a nightlight as well! My husband and I love being able to know my son's room temperature just looking at Kelvin and checking on its color. I also must say a huge thanks to Stephanie for the best customer service I ever had! Review: Adorable, easy to use, works well - Really great night light for a kid's room. We originally had the gro-egg, but decided to give this one a try for our newest born. The KELVIN is so much better in many ways: 1) it's cheaper, 2) you can toggle between Fahrenheit and Celsius (which is great since we use F in the US and gro-egg only comes in Celsius), 3) comes with a US plug, 4) you can actually choose your temperature ranges, 5) and it even displays humidity. I did a test to see if the product had accurate reading levels. Temperature showed 1 degree difference compared to my thermostat. Humidity level seems right given that we use a humidifier, although humidity levels can have a much bigger variance than temperature. But as long as it's within 5%, it's probably okay. It is more expensive than a regular night light but you're getting a lot of features, so in my opinion, it's worth it. ## Features - COLORFUL ROOM TEMPERATURE MONITORING: KELVIN changes colors depending on whether the room temperature is too hot, too cold or just right! Red for too hot, Amber for just right, and Blue for too cold. - HUMIDITY CONTROL FOR HEALTHY LIVING: Keep your family's health in check with KELVIN's built-in hygrometer. This digital humidity monitor ensures you're always aware of your room's moisture levels, guarding against congestion, stuffy noses, and dryness.

You can easily toggle between Fahrenheit and Celsius with the touch of a button. I hope that helps! Best, Stephanie, co-founder LittleHippo **Q: Does it have to always be plugged in? Can you turn the light off?** A: Hi, Thanks for your interest in KELVIN! KELVIN must be plugged in and includes a wall adapter. The night light is optional and can be toggled on or off. I hope that helps! Best, Stephanie, co-founder LittleHippo **Q: Are the lights that change color for the different temperatures really bright to where it would catch baby’s eye or do they stay pretty dim?** A: Ours is out of visibility from our 2 month old just due to outlet placement in the room but the lighting is bright enough to distinguish across the room but not so bright that it attracts your or your babies attention. Honestly with lights completely out it a minor amount of light in the room. Small nightlights for kids rooms are brighter. I love the Kelvin. Its been great for us **Q: Is this Bluetooth enabled to check the temperature remotely ?** A: No, KELVIN is not Bluetooth enabled. The color lights allow for a quick and easy temperature read.

Temp/Humidty Reader *by K***E on February 7, 2019* So, I don't have a child.. but I do have an office that's ice cold. I'd finally had enough of it being so cold and them telling me "the temp is set to 70, there's nothing we can do or people will be too hot".. SOOOO here came THIS unit! (For the record, I'd searched for other indoor thermometers and saw good reviews but also some Not so good reviews, even for the expensive ones. Because I just wanted one that simply Tells the Temp (and humidity) I decided on this adorable little unit.) Once received, all you do is Plug it in and it works, immediately. You don't have to get it set to the area or room or anything of the like, it simply works. Which I loved about that. It also shows the temp.. and changes colors Immediately, once it gets to the "comfortable" range! Because of this unit, when I first get in, in the morning.. it's still icy... BUT.. my office has began to turn up the temps for the day so my Kelvin just keeps on rising and getting to the "comfortable" range! (As shown in photos.) So of course, this would be ADORABLE for a Baby/Childs room.. equally as adorable for a desktop thermometer in an office! Would definitely purchase again and is now going to be my new "gift" to give for all of my friends that are having babies!! ## Frequently Bought Together - LittleHippo Kelvin Color Changing Night Light, Room Thermometer and Hygrometer (Humidity Monitor) for Nursery, Baby's Bedroom, Child's Room - Frida Baby 3-in-1 Rectal, Underarm & Oral Thermometer for Kids, Digital Baby Thermometer for Infants, Toddlers, & Kids, FSA/HSA Eligible - Frida Baby 3-in-1 Nose, Nail + Ear Picker: Baby Ear Cleaner + Baby Nose Cleaner and Nail Tool for Babies + Toddlers, Safely Clean Baby's Boogers, Ear Wax & More --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/58798858-littlehippo-kelvin-color-changing-night-light-room-thermometer-and-hygrometer](https://www.desertcart.us/products/58798858-littlehippo-kelvin-color-changing-night-light-room-thermometer-and-hygrometer) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-06*
