You cannot add more than one zone to a hose faucet timer. It is currently not possible to do so. Both device can use a hub to connect to the internet but this does not give you control of both of them at the same time. you will have to switch between active devices to access and program each one. I would suggest setting your program for the one, and then after that make the one that will use manual watering as your active device. It will be the one displayed in your app until otherwise changed. That way as soon as you open it you can just preform a manual water for that timer.
