Netatmo Urban Weather Station review: monitor conditions remotely - even rain - from your smartphone

£150 inc VAT

Manufacturer: Netatmo

Our Rating: We rate this 4 out of 5

Keep track of indoor and outdoor temperature and a lot more with this wireless weather station for iPhone and Android smartphones. Here's our updated review of the Netatmo Urban Weather Station - now with rain gauge

Netatmo Personal Weather Station

If - like most of the British population - you're obsessed with the weather, and you also love gadgets, Netatmo's Urban Weather should be right up your street. It works with an iPhone, iPod touch, iPad or Android device, but even if you don't have one of those, you can see the data on Netatmo's website

The kit consists of two sensors, one which stays indoors and another which resides outdoors. Information is sent via Wi-Fi to your router, and uploaded to Netatmo's servers.

To view the data, including temperature, humidity and pressure, you can install the free app for iOS or Android. As long as you have an internet connection, the app connects to the same servers and downloads the latest data from your station.

UPDATE: 24th April 2014 A year on from launch and Netatmo has launched a new accessory, the rain gauge, which costs £59. See below for full details.

Netatmo Urban Weather Station: design and installationNetatmo sensors

Both sensors look sleek in aluminium and white plastic, and the mains-powered indoor unit has a strip which glows various colours depending on its status.

The smaller outdoor sensor is powered by four AAA batteries and has a recess on the back for wall mounting (a wall plug and screw are included along with batteries). It isn't waterproof and the manual suggests you place it under the eaves of your house. Netatmo says the batteries should need replacing only once a year, but as we've had only a couple of weeks of testing, we can't verify that.

Being a keen gardener, I put it in the greenhouse at the bottom of the garden, some 40m away from the main sensor. Netatmo claims a range of up to 100m, but that's with no obstables. I had one or two signal problems during my testing, but there were several walls between the sensors. Moving the indoor sensor so there was only one wall separating the units solved the problem. 

As the units are pre-paired, that's one less job to do and makes for very easy installation.

Once you've installed the app (there are separate iPad and iPhone versions), you connect your device via its USB cable to the back of the main sensor and the app detects it automatically. You then pick a Wi-Fi network, enter the password and set a name for your station.

UPDATE: The latest version of the kit has only a micro-USB connection and setup is done automatically via Bluetooth instead of a wired connection. Your Wi-Fi settings are cloned from your iPhone, so there's no need to enter a password.

With that done, can you tap the top of the sensor to take a manual reading and check everything is working.

There's no subscription fee, so while the initial cost is high (perhaps too high - we'll come to this later), there are no server costs to pay.

Netatmo Urban Weather Station: apps

Netatmo iPhone app

I used both the iPhone and iPad apps and both are pretty good. The iPhone's smaller screen means you don't see as much information at once, but rotating it switches to graph view and sliding the bottom portion of the main screen downwards reveals more outdoor details (such as 24-hour low and high temperatures) plus a seven-day weather forecast.

Sliding it upwards displays more details about indoor conditions such as CO2 and noise levels. Unfortunately, it doesn't measure carbon monoxide.

Netatmo iPhone app custom alerts

Both sensors also measure humidity, but only the indoor module can sense barometric pressure.

There are some default alerts, such as when the CO2 level exceeds 1000ppm, but you can set custom alerts for any measurements.

For me, that meant I could set alerts to tell me if the greenhouse temperature got too high or too low: information that could save the loss of plants worth considerably more than the price of the kit.

You can create as many alerts as you like, and disable any or all of the default notifications.

There are plenty of uses for notifications. One of the defaults alerts you if the pressure drops more than 2mbar in an hour (an indicator of poor weather) and another warns if the indoor temperature goes below 10 degrees (alerting of a possible central heating failure).

Being able to view a graph of any measurement over time can be helpful in certain situations, but like the ability to record sound levels, may be an unnecessary frill for some.

Automatic measurements are taken every five minutes, so there's plenty of data to pore over, and it's easy to pinch to zoom in and out of graphs. We'd like to see an option for an absolute scale, though. Graphs automatically adjust the y-axis depending on the data, instead of starting at zero.

You can give others access to your Weather Station: all they need is the app, or to log in to the new website:

If you buy more than one Weather Station, it's easy to switch between them within the app.

UPDATE: Additional indoor sensors are now available to buy at £59 each and can be used to monitor temperature and air quality in more than one room. Up to three can be added.

There are no plans to sell extra outdoor sensors, but the rain gauge may soon be available with the main kit as a package.

Netatmo Urban Weather Station: rain gauge

Netatmo rain gauge

The latest addition to the Urban Weather Station is a rain gauge. It isn’t quite as stylish as the aluminium sensors in the main kit: it’s made entirely from plastic.

It’s powered by a pair of AAA batteries (like the outdoor sensor) and is obviously waterproof. It uses a tipping bucket mechanism to measure rainfall: a magnet passes a solenoid and the number of tips is counted. Netatmo says it’s accurate to within 1mm/hour (measuring as little as 0.2mm/hour).

Unless you’re a farmer, you probably won’t be too bothered by accuracy, though, and if you do need accurate measurements, the gauge can be calibrated in the app.

For most people, the two main reasons to add a rain gauge to your Urban Weather Station will be to set an alert when it starts raining (so you can nip out and get the washing in) and to figure out when you need to water your garden. You can see the current rainfall in the app (or on the website) as well as cumulative rainfall.

Otherwise, apart from the novelty of being able to track when and how much it rained, there’s not much incentive to spend an extra £60 or so on the gauge.

We tested the gauge before it went on sale and the app hadn’t been fully updated from French to English, leaving us to add a Nouveau pluviometre. Once paired, you can place the gauge up to 100m away from the base station. We tested at around 25m with several walls in the way and had no signal problems.

Netatmo rain gauge add module

To see rainfall in the app, you have to tap on the icon depicting the outdoor sensor. The top half of the display (on a smartphone at least) changes to show a weather symbol summarising the last hour’s conditions, a measurement of rainfall in the last hour, a cumulative total of the current day’s rainfall and a forecast for the day.

Graphs of rainfall over time are available when you select the gauge from the drop-down menu

Netatmo Urban Weather Station: bottom line

We've already mentioned that there's no carbon monoxide sensor, which would go some way to justifying the steep price. Another gripe is that there's no display on either sensor, so you can't see the temperature without firing up the app.

Even though you can now pick it up on Amazon for just under £120 it's still a lot of money given that a basic weather station with an outdoor sensor  and hygrometer can be picked up for around ten times less.

The advantage with the Netatmo, of course, is remote monitoring and alerts. If you need these features, and want to be able to track measurements over time, the price may not be such a barrier.
