Homey Pro (Early 2023) - Powering - PoE - Powerbank etc

As it was getting offtopig in the - The new Homey Pro — Ask Me Anything
I moved it as it is an interesting discussion:
How can I power the Homey Pro (Early 2023) on an alternate way?
fe using a PoE solution, Powerbank, UPS, etc.

Discussion from above is moved here!

This one is different from other topics as Homey Pro (Early 2023) has an Ethernet adapter, and USB-C connector. Maybe even other Power Requirements:

Just buy a passive USB splitter… %product-title% kopen ? Conrad Electronic

You can also buy a passive splitter with a normal 12v device connector. Add a little powerbank to the mix, connect homey to the powerbank, powerbank to the passive poe splitter and you have a mini APC keeping homey alive, powerd by POE. splitter is like 12 euros and a dumb little powerbank from ali about the same

Not all powerbanks can charge itself and give power to connected unit (here Homey) simultaniously.

Thats correct, heres a good article on pass-through charging: Can a power bank charge and discharge simultaneously?

This article is missing 1 important part too, most power banks are not a UPS (uninterruptible power supply), they will take several milleseconds up to a second to switch from pass through to battery mode (some even don’t do that at all), which is enough for Homey to still reboot.
