vSMART app shows inconsistent or delayed temperature updates compared to the thermostat display.

Steps to improve sync:

• Check internet speed: Run a speed test on your home network and ensure upload and download speeds are adequate.
• Force refresh: Pull down or refresh the app screen to request updated data from the cloud.
• Limit devices: Log out of unused devices or sessions that may be polling the system excessively.
• Update app: Install the latest version of the Vaillant app, which may include performance improvements.

Minor delays are normal in cloud‑based systems; large or persistent discrepancies may indicate server issues outside your control.
