Standing in the baby aisle, every thermometer looks much the same. Here's what actually separates a useful one from a number on a screen, so you can choose with confidence.

What actually matters

Ignore the marketing for a second. The things that count are accuracy, where it reads, whether it helps you act on the number, and whether it travels with you. Everything else is nice-to-have.

Accuracy and where it reads

Heat rises, so where a thermometer sits changes what it tells you. Then there's windows, heating and cooling vents, drafts from doors being open.. all impacting the number you're given. A reading taken at cot level, near your babe, is more representative than one from a shelf or a wall. Placement matters as much as the sensor itself. It’s the same reason a baby monitor’s temperature reading can be off.

A thermometer on a shelf reads 24 degrees while a monitor at cot level reads 19 degrees, five degrees cooler

Same room, two heights: air up high reads warmer than the air at the cot.

Does it just show a number, or help you act on it?

A number is only half the job. The more useful tools turn the temperature into something practical, like a TOG or dressing suggestion, so you're not translating it yourself at 2am.

Our TOG guide covers what suits each temperature, and a degree-by-degree dressing breakdown covers the exact layers for tonight.

Portability and no-WiFi

Nurseries aren't the only place your babe sleeps. A thermometer that runs on rechargeable battery, doesn't need WiFi, and packs into a bag keeps working at grandparents' or in a hotel.

Where Orbie fits these criteria

Orbie is an environment monitor rather than a bare thermometer. It reads temperature and humidity at your babe's level, works without WiFi, travels with you, and turns the reading into dressing guidance in the app. We built it to do more than show a number.

Why parents choose Orbie

Set against a plug-in nursery thermometer, the difference is not the number. It is everything you do with it.

Common questions

✦ What is the most accurate baby room thermometer?

Accuracy depends as much on placement as the sensor. A thermometer that reads at your babe's level, where they sleep, gives you a more representative reading than one mounted up high.

✦ Do I need a smart nursery thermometer?

Not necessarily. What matters is whether it reads accurately where your babe sleeps and helps you act on the number. Some parents like app guidance; some prefer a simple display.

✦ What's the difference between a thermometer and an environment monitor?

A thermometer shows a number. An environment monitor reads temperature and humidity, turns it into guidance like what to dress your babe in, and keeps a temperature history you can look back on.

✦ Is 25 degrees too hot for a baby's room?

There is no single safe number. Red Nose is clear there is no perfect room temperature, and no evidence that any one figure makes sleep safer. You will see a comfortable range of about 16 to 20 degrees cited around the place, so 25 sits on the warm side of that, but the real move is to dress your babe lighter for the room you actually have rather than chase a target.

✦ Do I still need a thermometer if my baby monitor already shows temperature?

Often yes. A monitor's sensor usually sits across the room and up high, not down at the cot, so it can read warmer or cooler than the air around your babe. A reading taken at their level is more representative.

✦ Does Orbie need WiFi?

No. Orbie pairs to your phone over Bluetooth, so there is no WiFi setup and it travels with you. The Stellar Baby app uses your phone's own internet to sync the readings.
