Hive thermostat randomly restarts or reboots during normal operation

Safety first: For wired models, isolate power before removing covers.

• Secure batteries: Ensure batteries fit snugly and contacts are clean. Slightly bend contacts (gently) to improve pressure if needed.
• Check for vibration: Avoid mounting the thermostat on surfaces that vibrate (e.g. stud walls near doors that slam).
• Firmware update: Apply any available firmware updates via the Hive app.
• For wired models: Have a professional check the low-voltage supply from the receiver for stability.
• When to call a pro: Frequent reboots usually indicate a failing power regulator or main PCB, requiring thermostat replacement.
