Smart Hose Timer Hub Only

I have a smart hose timer and need to purchase a second. I plan to get the timer only but I’m concerned that the hub is across our house at some distance, but under 200 feet.

If the timer is unable to connect, is there an option to purchase the hub only that I’m just not seeing?

I have not seen the hub for sale by itself. I may have just not looked at the right time or missed it. If not, I would guess it will become available.
