Hi,
I’m running HassIO.
I’m making an uninterrupted power supply (UPS) for my Pi 3.
I need my UPS to be able to send a signal to Pi through GPIO pins to shutdown the HassIO safely.
Similarly, to boot up too.
Is this possible through HassIO?
That should be perfectly possible by using the GPIO component for the UPS and creating an automation that triggers on state changes and calls the service ‘hassio.host_shutdown’.
