I cannot connect my Netatmo devices to my Wi-Fi network. What should I do?


  1. Some Wi-Fi networks are not compatible with Netatmo devices:
    • Public and enterprise networks.
    • Networks that only use the 5GHz band.
    • Networks behind an authentication portal.
  2. Some networks that use wireless repeaters can cause problems with Netatmo devices.
  3. Make sure your smartphone/tablet is connected to the same Wi-Fi network that will be used by the AC Controller before beginning the installation.
  4. Check that your smartphone is receiving the Wi-Fi signal next to your AC.
  5. The AC Controller will not work as expected if it is powered by a USB cable. It must be plugged to the grid with one of the provided power adapters to operate normally.


Several factors can prevent the Netatmo AC Controller installation to complete.
In this article, you will find a few simple tips to help you connect your devices:

  1. Reboot your Wi-Fi router.
  2. Uninstall the Home + Control app, reboot your smartphone/tablet and install the Home + Control app again. No personal data or settings will be lost in this operation.
  3. Check the AC Controller power supply.
  4. If the AC Controller needs to connect to a Wi-Fi repeater, assign the repeater a name (SSID) different from that of your router. If that still doesn't work, try to connect the AC Controller directly to your router (by changing the Wi-Fi network your smartphone is connected to). If it works, check the repeater settings.
