If the connection between Netatmo devices and the Home app are down, follow these steps:

- Check that the Netatmo modules are properly connected to a power supply and to the internet.

To check the power connection:

- Unplug and reconnect your indoor module. Check to see if the LED light flashes three times. If it doesn’t flash, try using a different micro USB cable and power supply with your indoor module.

- Force-stop and restart the Netatmo Weather app on your smartphone. It can take up to 10 minutes for the station to start up again.

To check the internet connection:

If you have recently changed your router/wifi settings (e.g. your wifi password/wifi name), you will need to pair your Netatmo devices in the native Netatmo app again.

1. Move the indoor module closer to your router and make sure there are no metallic or electrical objects between them.
   
   
2. Restart your Internet-Box. 
   
   
3. Close the Home app completely, then re-open it.
   
   
4. Open the Netatmo app and check whether the devices are now paired with it.
   
   
5. Unplug the Netatmo device for at least two seconds, then reconnect it.
   
   
6. Remove the Netatmo device from the Home app, then add it again.
   
   
7. Reinstall the Home app.
   
   
8. Restart your wifi router.

After each step, check to see if the problem is fixed.
