How do I run power to a USB-C powered sensor? (lemmy.nz)

I'm just bought an Airgradient air quality sensor (actually two, an indoor and an outdoor).

I want to mount the outdoor one but it needs a USB-C power supply. I can run a cable but power isn't exactly close. Do I somehow find a 10m USB-C cable and run it through the roof to the sensor that I mount on the side of the house? What's a normal way of getting USB-C power to an area far away from the closest power point?

POE network switch + RJ45 to USB adapter. I run a presence sensor as a test sensor in my hole office via a Door switch. Works great.

POE is how I power other stuff run through the roof (wifi and security cameras). This might be the easiest option, thanks!
