How to monitor output in HA

How can I see state of output in HA? I want to monitor for example state on power_supply. I can’t find any triggers to do so. Thank you for help, Jan.

We need a bit more information about what you’re trying to do.

If you’re talking about automations, triggers relating to power usage might be switch or light entities changing to ‘on’…

I have a simple GPIO output and Power Supply Component and I want to see the state of the Power Supply. Since I cannot add output to HA I need help how to do it.
I read lot of docs and it looks like I could create a binary_sensor and somehow set the the state from the PS Component, is this possible?
