Thermostat shows incorrect time or 'Time Sync Error', causing schedules to run at wrong times

Safety first: No electrical work required.

• Check internet connection: Confirm that your router has internet access and that the Hive Hub is online.
• Router settings: Ensure that NTP (Network Time Protocol) is not blocked by firewall rules.
• Manual correction: Set the correct time and date on the thermostat if allowed, then re-enable automatic time sync in the app.
• Firmware update: Apply any available updates to the hub and thermostat to fix known time sync issues.
• When to call a pro: Persistent time sync errors despite a working internet connection should be escalated to Hive support.
