The WXMS Smart Moisture Sensor measures the moisture and temperature of your soil. Once you set a threshold moisture level (20%, 40%, 60%, 80% or 100%), then any WX Tap Timer connected to the WXMS Smart Moisture Sensor will stop watering scheduled Starts once the moisture level is at or above the threshold.
In some cases, the WXMS Smart Moisture Sensor connected to a Wi-Fi Hub will affect all WX Tap Timers connected or only affect one WX Tap Timer. This depends on the version of your Wi-Fi Hub.
To check the main module version of your Wi-Fi Hub:
- Open your Wi-Fi Hub in Holman Home
- Tap the pencil icon (top right of the screen)
- Tap Device Update and then check the Main Module version
If the Wi-Fi Hub Main Module version is 1.2.8 or greater:
- This hub will work with both WX1 and WX2 Tap Timers
- It is possible to add 4x WX1/WX2 Tap Timers and up to 8x WXMS given an optimal environment
- Each WXMS Smart Moisture Sensor will affect only one WX1 Tap Timer or one zone of a WX2 Tap Timer
If the Wi-Fi Hub is version 1.2.1:
- Please check the MCU version of the WX1 Tap Timer
- Open the WX1 Tap Timer, choose the Help screen and then check the MCU version – just the first two parts of the information.
WX1 Tap Timers with MCU versions HOL9-017 or HOL9-018
- These hubs will only work with WX1 Tap Timers
- It is possible to add 4x WX1s and 1x WXMS given an optimal environment and one WXMS Smart Moisture Sensor will affect the scheduled watering of all attached WX1 Tap Timers
WX1 Tap Timers with MCU versions HOL9-028 or HOL9-030
- These hubs will connect with WX1 Tap Timers
- These hubs will also connect a WX2 Tap Timer BUT not as a Holman device
Please note: WX2 Tap Timers can NOT be supported with these hub versions
- It is possible to add 4x WX1s and 4x WXMS (given an optimal environment) and each WXMS Smart Moisture Sensor will affect only one WX1 Tap Timer
