Changes to heating schedule in the app do not appear on the thermostat; app may show a schedule synchronization error.

Note: This affects automation but not basic manual control.

• Check Relay connection: Confirm the Relay is online in the app (no Wi‑Fi or internet errors). Resolve connectivity issues first.
• Force sync: In the app, slightly modify the schedule (e.g., change a setpoint by 0.5°C) and save. This often forces a new sync.
• Reboot devices: Power‑cycle the Relay and close/reopen the app. Wait a few minutes for synchronization.
• Recreate schedule: If errors persist, delete the problematic schedule and create a new one from scratch.

Persistent schedule sync errors with a stable connection may indicate firmware issues; contact Netatmo support for further diagnostics.
