Hi Lance,

Currently Netro can only run one zone at a time, so different zones for the same time cannot be created. This limitation is due to the fact that the power adaptor can only provide 600mA max current which is only enough for running one valve (when master valve is used). In the future, we will enable turning on 2 zones at the same time for Netro Spark controller. It takes some time and the time is uncertain.

Thanks,

Netro Support
