I am setting up automation for my plants and trying to figure out what the Smartthings Hub does. My setup includes 9 TP link outlets (individual and power strips), 4 Switchbot temperature/humidity sensors, and a Switchbot wifi hub. I was able to set everything up in the Smartthings app to run the fans if the temperature or humidity gets too high, and to run the misters if the humidity gets too low.

I bought a Smartthings Station to use as a hub, but I’m not sure what it does or if it’s even necessary. I thought it would serve as a central unit to monitor and trigger those automations if my phone is not around. Is that correct?

If so, does it do this automatically after being added to the app? Or do I need to set it up to add those devices/routines to the hub?
