Troubleshooting
When no sensor readings are displayed in the app, check if the green
LED on the gateway is permanently lit. If not, please check if:
- The gateway is properly connected to the power plug, the router and
is turned on.
- Restart the station by removing the batteries for a minute and
reinserting, to restart the device.
- Your phone is connected to the internet.
- The signal is weakened by thick walls and ceilings. Put the device in
operation near the gateway and then locate a suitable location.
