Hello, I have been running HA on my Raspberry Pi 4 for ~a year, and I think that my PSU is underpowered. How can I check if it receives enough power? The PSU was always slightly underpowered, but it worked for nearly a year but now it’s coming back onto me… Best Regards Aaron

By changing your psu with more powerfull one…? It’s just usb-c connector… Note that psu on ANY device should always be more powerfull than required power draw (around 20-30% minimum). Using PSU “at the edge” is calling for troubles, especially if you know that psu is too small. No-one likes to run …
