General discussion • Restart r-pi on UPS after shutdown

Hello,

I have a simple use case but maybe I miss something....

I have a r-pi 4 and UPS the pipower-v2. basically I using the r-pi to output production on my machine. (node red - influx- grafana) when they stop the machine the power is down and then I can stop properly the r-pi thanks to the pipower-v2.

However I didn't find a way to restart the raspberry when the power is back on without having an external switch (they always forgot to press....) or another MCU that when it boots it will put either the wake_on_gpio to ground or the EN pin of the pipower-v2 to ground....

Basically I can detect via the pipower-v2 that the power is back on and I would like to start the r-pi......

Is it a "clean" way of doing so? It must be easy and I missed it .... thanks
