The big advantage is of course the app on iphone. I know the weather with me even when I'm away.
It is an anecdote, but suffered water damage, I was able to find the approximate time of the beginning of the flight through history.
Certainly, the station is expensive compared with other weather stations, but it is truly original and I check the app several times a day. I am a geek and I love it! ;)
I also realized the need to air the rooms regularly to keep CO2 levels within acceptable limits.
I would like to add an indoor station in my daughter's room but it is not possible for now. After contact, Netatmo said they worked there.
Warning, this station must be within range of a WiFi network to communicate and transmit its information.
In summary, cheap but effective and reliable. The support is good and regular updates. I just regret that there was no carbon monoxide detector, it would be a real breakthrough!
