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

[Dijker]

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:

Homey powerbank or UPS

Hi All, I’m starting to use Homey as a alarm system as well. Within my fuse box I have a UPS powering the router, accesspoint, etc. Homey is the central hub for all devices and I want it to keep working in case of a power failure as well. All alarm nodes are mainly battery powered anyway. My idea is to buy a powerbank and have it always plugged in. The powerbank output will then be connected to homey… and instant cheap UPS function would be added. But will that work? Are there any requirement…

UPS for homey and router

Hi, I currently have no UPS or similar things setup for my Homey and Wifi Router. Since Homey is responsible for runing flows which helps in the case of emergency (Adjust lights, turn on siren etc.) it seems dumb to not implement redundancy incase of power outages. What setups are common to use? Are there any Gotchya’s I need to watch out for when considering buying a UPS? Is there a different more prefered approach I should consider? I assumed this to be a common use case but the “Your to…

Using Homey in a motorhome

Homey uses 2 Watt with LED ring off up to ~5 Watt, with the default LED ring at 100% Maybe somewhat more when sending and on heavy load. You could use a USB powerbank as el cheapo UPS, if that powerbank does not cut the power when switching between loading and not. Be warned these are often not made for continue loading and defective batteries can catch fire.

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.
