I have a small ranch far out in the country where the only internet access I have is through an android tablet upon which wifi hotspot is enabled. The tablet acts as a connection point for all devices in the cabin that need internet access.
I am frequently hours away with the air conditioning turned off. I want to use SwitchBot to press the "On" button on the remote control for my air conditioner from a hundred miles away (a few hours before I arrive) using my android cell phone. Will a single SwithcBot (no hub) be all I need?
