When the app shows "Cloud offline" or sensor data stops refreshing, this is usually caused by a broken connection between the hub and the internet - or the app being unable to fetch current data.
Work through this step by step:
Check your internet connection: is Wi-Fi working on other devices?
Check the hub: is the LED on the hub lit? If it's showing as offline, follow the steps in "My Hub is offline".
Restart the app: close it completely and reopen it.
Check whether an app update is available - outdated versions can cause connection issues.
Restart your smartphone and open the app near your sensors.
If you don't have a hub: sensors only transfer data via Bluetooth when your smartphone is nearby. Open the app next to your plants and wait a moment - data will sync automatically.
If the issue persists, check our status page for any known outages, or get in touch via the support chat.
