6. Provozní režimy

The smart switch module supports three main working modes:

  • Režim samosvorného uzamčení: In this mode, connected devices can be turned ON or OFF remotely and will maintain their state until another command is received. This is suitable for lights or appliances that need to stay on or off for extended periods.
  • Režim pomalého posuvu (momentální): When activated, the relay will turn ON for a set duration and then automatically turn OFF. The default inching time is 1 second, but it can be configured in the APP from 1 second to 3600 seconds. This mode is ideal for applications like garage door openers or electric curtains.
  • Režim propojení: This mode ensures that when one relay is turned ON, the other relay is automatically turned OFF. This is commonly used for controlling motors with forward and reverse functions, preventing both directions from being active simultaneously.
