Our take
On this page
Our verdict
The GroEgg2 does one thing the NHS and The Lullaby Trust both recommend: it measures the room. Its colour bands, as given on the listing (blue at 16°C and below, yellow for 16-20°C, orange for 20-24°C, red over 24°C), make the official 16-20°C range easy to see from the doorway, and the display gives the exact figure. The night light has three brightness levels. It does not measure your baby; you still need to feel their chest or the back of their neck. The listing describes it as a toddler night light, and it needs mains power through a 200 cm USB cable, so position it and the cable well out of reach of the cot.
Using it with a sleep bag
Use the colour as a prompt to check the maker's tog guide and your baby, not as an instruction on its own. The Lullaby Trust explains that materials, layers and individual babies all change how warm a baby actually is.
FAQ
Is a simple thermometer enough?
Yes. The official advice is to use a room thermometer; any accurate one meets it.
Does it work on batteries?
The listing describes it as USB powered.
