I did not spot this in the quick start with the Wifi hub, but is there a maximum number of timers a single Wifi hub will support?
Is there a target date for when the Smart Hose Timers would be available for purchase without an accompanying hub?
At this time, the Hub will support 4 timers. It is possible this may increase in the future. I do not know when the individual timers will be available, but will see what I can find out unless someone else responds first.
