Found an active POE splitter that got my attention ([here](https://nl.aliexpress.com/item/1005001356576287.html?spm=a2g0o.productlist.0.0.4a241cc0Cd7G7L&algo_pvid=102abff7-cf5f-40b5-8e11-9b1ce7ac0439&algo_exp_id=102abff7-cf5f-40b5-8e11-9b1ce7ac0439-1&pdp_ext_f=%7B%22sku_id%22%3A%2212000015796991602%22%7D&pdp_pi=-1%3B4.5%3B-1%3B91%40salePrice%3BUSD%3Bsearch-mainSearch) on Ali):

I assume [these](https://nl.aliexpress.com/item/32805447244.html?gatewayAdapt=glo2nld&spm=a2g0o.detail.1000060.2.66c86b3cT3fMnU&gps-id=pcDetailBottomMoreThisSeller&scm=1007.13339.169870.0&scm_id=1007.13339.169870.0&scm-url=1007.13339.169870.0&pvid=c0c2f827-e31b-42b1-863f-2176d632c1cd&_t=gps-id:pcDetailBottomMoreThisSeller,scm-url:1007.13339.169870.0,pvid:c0c2f827-e31b-42b1-863f-2176d632c1cd,tpp_buckets:668%232846%238114%231999&pdp_ext_f=%257B%2522sku_id%2522%253A%252264304028955%2522%252C%2522sceneId%2522%253A%25223339%2522%257D&pdp_pi=-1%253B1.01%253B-1%253B-1%2540salePrice%253BUSD%253Brecommend-recommend) 5.5mm female DC jacks will fit to them, so I don't need to start cutting of my cables:

That way the setup becomes very solid and simple:

Unless somebody sees something nasty that I have forgotten, I am going to put some stuff into my shopping basket 😉

BTW on the above link (about the splitters), I see also an example image of a Raspberry being powered via POE:

I assume you will need a more expensive POE switch to be able to power a series of those devices. However just wanted to share it here, because it might trigger the creativity of some folks in this community...
