Netatmo – a smart weather station

Netatmo is a French company that makes smart gadgets for the home. One of their products is a smart weather station . The biggest reason I got a weather station was actually that I lacked an indoor thermometer. Sure, you can buy a regular unsmart cheap thermometer, but I thought it would be fun to have a more complete weather station that can save weather data in a longer perspective. On another of my blogs I have published today’s weather forecast for Malmö for a while and think it’s fun to be able to go back and check how the weather was on a certain day. With a smart weather station, I can measure different values ​​myself and get some other statistics.

Unpack and get started

In the box you will find two tubes of aluminum. One is for indoor use and the other for outdoor use. The indoor part has an AC adapter and is plugged into an electrical outlet, while the outdoor part only runs on battery. My dilemma is certainly that I do not have a really good place to place the outdoor part really outdoors. It ended up in a shady spot on the balcony. The unit itself is waterproof but should not be rained on according to the instructions. I will get some incorrect values ​​from my outdoor unit but will have to live with it.

When the devices were unpacked, it was time to connect them to the wireless network here at home. This can be done both via a USB cable to the computer or via Netatmo’s app in the mobile. It was not simple but not overly difficult either. You connect one device at a time. If you want to expand, it is possible to connect more accessories such as rain gauges and anemometers. And extra indoor units.

When the devices are connected, they start delivering measured values ​​that you can see in the app or via Netatmo’s website. By the way, you need to create a Netatmo account when you set up your devices. The measured values ​​are sent there and they also end up on the Netatmo Weathermap. On this weather map you can see other weather stations in your area and compare data. Here I see clearly that I do not get correct values ​​from my unit that is on the balcony.

Measurement values ​​and automation

The measured values ​​you can get out of the weather station are for the indoor part temperature, humidity, carbon dioxide content, air pressure and a sound meter. From the outdoor unit, temperature, humidity, air pressure and air quality are reported. If you use IFTTT, you can use the values ​​from the weather station to automate further. For example, start a fan if the indoor temperature becomes too high. Or get a warning if the carbon dioxide content becomes too high so you can open a window to ventilate.

I have set up a few different automations to test and it seems to work great. Time will tell what I want to do with the information from the weather station, but it’s fun to be able to see my own information about the weather and climate here at home. It will probably be even more fun when I get a little more historical data to work with. Do you have a smart weather station yourself and what do you think?
