Can I connect the Smart Moisture Sensor to only one of my WX1 Tap Timers?

  • As the Smart Moisture Sensor is connected via the Wi-Fi Hub it will attach to all other WX1 Tap Timers on the same hub.
    You would need to purchase another Wi-Fi Hub (that does not have a Smart Moisture Sensor connected) and move all WX1 Tap Timers to this new hub.

Why does the Smart Moisture Sensor connect to both my WX1 Tap Timers?

  • When a Smart Moisture Sensor is connected to a WX1 Tap Timer it does so via the Wi-Fi Hub.
  • This means any other WX1 Tap Timers attached to the Wi-Fi Hub will also automatically be connected to the Smart Moisture Sensor.
