Has anyone tried to place a battery between to power adapter and a Homey Pro 2023 so that it can stay powered for some time in case of power failure? I use the Homey also as an alarm system and in case of an alarm it would be better if the Homey Pro stayed working for some time (sensors are battery …

Not sure that would an issue if you have enough current to compensate for the 0.2V difference.

Current cannot compensate for lack in voltage.

HP2023’s were initially shipped with a 5V power supply, which caused undervoltage issues, so Athom had to replace them all with 5.2V power supplies :man_shrugging:t3: (0.2V happens to be the voltage drop of a Schottky diode, so my guess is that there’s either a misplaced diode in the Ethernet adapte…

It depends, sometimes it can without any issue at all. It might not work with Homey, but in a lot of everyday useage you would never notice.

It might work. Undervoltage of HP2023 results in less core speed, but most of the time it will not be notable.

I’ve looked into doing this too, and my limited research has led me to believing that some Xiaomi power banks will do the trick, particularly model PLM03ZM and Qb826g

Have a UPS in between, works fine. When the power is out, all communication with battery powered devices works. All others are obvious not working

I think a UPS model like the APC BE400 would be sufficient and easy to install. Don’t forget to put your router and maybe your Fiber Termination Unit on it as well.

This Powerbank can remain connected to the mains 24/7 and had enough reserves to bridge other devices in the event of a power failure: https://www.digitec.ch/de/daily-deal

it’s useless if you don’t have internet connection. The best way is how @Robb said. You need a small UPS and connect Homey, router + Fiber Termination Unit (ONT, etc)

I guess it’s only useless when one needs internet dependent stuff on their Homey?
Everything which doesn’t need internet keeps on running.
Managing a Pro 2023 without internet should be possible according to Athom marketing, but howto do that is unsure
