Netatmo test: additional indoor module for the weather station

Did you know that the weather is a very Western passion? Indeed, when we speak of connected weather stations, our Chinese friends often look at us with blissful faces. What interest since we each have a smartphone able to tell us if it will rain or not?

At Les Alexiens, however, we like to have and follow a truly local weather forecast… It has to give rhythm to our seasons, our lives often, and in this, the Netatmo weather station is a must have for an Alexian although this one is only partially compatible with Alexa.

Although the brand acquired in 2018 by Legrand does not only focus on rain or shine and, among other things, markets a indoor surveillance camera or a connected thermostat, let's talk a little about this Netatmo weather station. The base model consists of an indoor and an outdoor module, that's fine, but the temperature data or the CO levels2 or even humidity are not always identical from one room to another. An indication, for example, of an above-average concentration of CO2 (around 1000 parts per million or ppm for friends) requires airing the room as quickly as possible, but not necessarily the entire house. Hence the idea of ​​adding additional Netatmo modules. Let's see in more detail what it offers ...

Netatmo additional module: a modern and unified design

Unboxing and presentation

The Netatmo module is presented in a packaging as nice as the weather station, but smaller since it only contains one module. Logic ! We always find the same care of the graphics with the photo of the module, the brand and the indication of the content on the front face. On the back are technical information on the measurement ranges of the three parameters (temperature, humidity, CO2), and this in 6 languages. One side shows, in the form of a logo, these three pieces of information while a fourth mentions alerts in the event of CO containment.2. A box below finally specifies that it is possible toadd up to three indoor modules at the same station. The last side, for its part, reveals a visual of the application and the data collected.

Once the packaging has been opened, we discover our tubular module in the same gray aluminum as the two others that made up the basic weather station. It is well wedged and is accompanied by the four batteries necessary for its operation. The little flyer attached, apart from telling us how to open the device will not help us any more. This new module of 350 grams does 10.50cm from above for 4.50cm in diameter either the same dimensions as that intended for the exterior.

Before seeing its addition to our weather station, let's take a look at the technical sheet of the additional module ...

Netatmo Météo: a useful additional module

The simplest installation

As this is an additional module to the weather Channel, we had obviously already installed theNetatmo app and the account needed to manage it. So we just need to register the new device in the settings. How to do ? Very simply. Follow the guide !

In the left pane on the home page of the application, click on " Settings ", then on the new page that opens, we will simply choose "Add / remove a module".

The new page that appears asks us to plug in the main module. As this is already in operation, we can go directly to the next step, which consists of pressing the top of the “station” module to switch it to pairing mode. It is only from this moment that we can take care of our new device and open it to put the batteries in. No need to turn the base of the tube, it is with a coin that you can unscrew the cover. This was the only information needed on the flyer enclosed in the packaging.

A coin is enough to unscrew the cover.

Once the batteries are placed (respecting the direction of the requested polarities), the pairing between the base and the new device is done.

Once the recognition is done and a name given to our module, it appears in the list of installed products.

It is necessary to wait a little so that the new data arrives at the station and is displayed on the application and on web interface. A calibration of the CO probe2 will. Allow 6 hours for it to be effective, 24 hours for it to gain in precision. Indeed, Netatmo considers that a part will drop at least once a day around 400 ppm and will calibrate itself on the basis of this principle. Be sure to ventilate this room properly at least once in these 24 hours.

From now on we can ask Alexa to provide us with the new data that the indoor modules collect, specifying which device interests us. Unfortunately, on the other hand, Netatmo has still not given us a multimodal skill and no graphic display is made on our Echo Show.

To access the customization of alerts, from the main settings page, click on "My weather station", then click all the way down on "Customize notifications". It is also possible to create personalized outdoor or indoor notifications.

We do receive push notifications according to those requested and in the photo below, you see two notifications because these are the two indoor modules that each sent an alert.

This add-on to the Netatmo weather station will easily find its place and provide additional data for a new room. Sporting the very successful design in aluminum, it will logically go perfectly with the rest of the installation. Although a little expensive, this probe is very interesting for Netatmo users. It is still a shame that the skill is not multimodal
