Authentication problems with netatmo

Due to a technical change on the part of the netatmo infrastructure, it is necessary to install and use the latest myatmo version available in the App Store.

Old versions of myatmo are no longer supported due to the changes to the netatmo authentication, an update of these old myatmo versions is not possible.

It is therefore essential to update to the latest version of myatmo. If you are using an old iOS version that is no longer supported by the latest myatmo version, you must update iOS or use myatmo on a device that has the latest iOS version installed. Due to technical limitations of old iOS systems, it is not possible to provide the latest myatmo version on outdated iOS versions.

 myatmo shows outdated data


If myatmo shows outdated readings from your weather station, which may be several hours old, there can be various reasons.

  • Make sure that your weather station is correctly connected to your WiFi network
  • Make sure you have an internet connection
  • Make sure that all of your modules connected to your weather station (with the exception of the main module) are supplied with fresh batteries
  • Make sure there are no known server problems on
  • Check the official netatmo user forum at whether other users may have similar problems
  • Even if the official netatmo app shows current data, but outdated data is shown in myatmo, there may be a server problem!

Contact netatmo customer service at if the problems persist. We have no insight into the netatmo infrastructure and cannot help if myatmo displays permanently outdated data.
