Thermostat shows E18 and geofencing or cloud services are unavailable.

Safety first: No mains work is required for network checks; do not open mains devices without isolating power.

• Check internet: Verify that the home internet connection is working on other devices.
• Router settings: Ensure the router is not blocking outbound connections from the Wiser HubR. Disable overly strict firewalls temporarily to test.
• App and firmware updates: Update the Wiser app and check for HubR firmware updates.
• Reboot HubR and router: Power-cycle both devices and wait a few minutes for reconnection.
• Account sign-in: Log out and back into the Drayton/Wiser account in the app. If E18 persists, contact Drayton support to check cloud service status.
