hello,
i was wondering if there is by any chance a way how to connect some small relay 5V? via usb to some pc as cubox/rpi … so i can somehow control that relay remotely via HASS.

thanks

Does it have to be USB?

There are many cheap ESP relay modules (wifi) that work well with ESPHome.

whats the usage for these? As I understand you can power on/off USB port - ie it’s like controlling USB charger - 5V on/off?

thanks

You can switch on/off anything that uses USB power.
