I am planning to run Hassio on a laptop, (built in UPS 
) but on the laptop I also want to run y Ubiquiti controller. if I set up SSH on HASSIO, how will I be able to access the Ubiquiti controller through SSH?
Might simply be a difference in the port you SSH in to. One for Hass.io, the other for the base OS.
Here’s info for developers which may be useful in your situation:
