How to add to VENUS app

1. Activation
  • Press “Add button” (button ‘+’) in app
  • Press program button once
  • The LED will blink when the inclusion completes
  • Wait for VENUS scan & detect this device and inform in app
2. Reset then re-add
  • Press “Add button” (button ‘+’) in app
  • Press and hold the button for approx. 2 seconds to reset
  • The LED will blink to indicate device is reset
  • Press program button once to add
  • The LED will blink again, the adding completes
  • Wait for VENUS scan & detect this device and inform in app

LED indicator

1 fast blink Wake-up, notification sent (after quick button press and device is in z-wave network)
2 fast blink Water alarm
3 fast blink Temperature Alarm (either high or low setpoint triggered)
4 fast blink An active alarm has been cleared (when a water alarm or a temperature alarm is no longer active)
5 fast blink Low Battery (repeated every approx. 40 seconds)
1 slow blink Device in z-wave network (also, after button held while in-Network)
3 slow blink Device is removed from z-wave network (also given if adding was not completed)

Wake-up information

  • Wakeup1: Power saving design wakes up every 4 seconds to test water and freeze sensor
  • Wakeup2: Once every 4 approx. hours (default) unit wakes up to send a notification to controller to query and update the status of the unit. A controller can change this wakeup interval. Battery life is decreased when the wakeup interval time is shorter.
