Can Sync be used to recover data from the server?

Need Help With My Project

Is there a way to use Sync to recover int variables from the server after a power outage and reboot? I have a spa pool controller and want to reinstate the setTemp variable after a power outage, so that it continues at the previously established set point.

Perfect! I missed the fact that syncAll called a BLYNK_WRITE function
