Time Sync Card

This feature is only available in ESP-DASH Pro

A utility card for synchronizing device time with the MCU using browser time data. Enables precise timekeeping functionality while requiring both device and MCU to be in the same timezone for accurate synchronization.

💡

Time sync card grabs the time from your browser, so only use it when your device and MCU are known to be in the same geographical location/timezone.

Callback

  Serial.println("Time Sync Triggered: "+String(value));
});

Updater

Time sync card doesn’t require any updater.
