Dear customer,

One water valve can only be assigned to one sensor and cannot be connected to multiple sensors simultaneously. You can add the other sensors as standalone sensors.

If the Pixie and Whisperers are installed in different areas, they cannot work together to optimize your garden watering. This is because Pixie and Whisperers require communication with each other to intelligently manage the plants' watering needs. 

If you have any further questions or concerns, please do not hesitate to contact us, and we will do our best to assist you.

Thanks,

Netro Support
