Hi @henxan,  
I'm also a cable guy, and I have used in my home the setup from [this](https://discourse.nodered.org/t/use-a-poe-switch-to-power-esp32-wired/58696/20) discussion.  
Although the wt32-eth01 board is not POE, it works fine in combination with this [poe splitter](https://nl.aliexpress.com/item/1005001356576287.html) which offers me also 5V voltage to power my sensors.  
I am very pleased with it.  
Bart
