Hive thermostat loses its schedule and reverts to default settings

Safety first: No mains work required.

• Recreate schedule: Use the Hive app to set up a new heating schedule and sync it to the thermostat.
• Avoid frequent resets: Minimise unnecessary power cycling or factory resets, which can stress memory.
• Firmware update: Apply any available updates to address known memory issues.
• When to call a pro: Repeated loss of schedules suggests failing non-volatile memory; the thermostat should be replaced.
