I’ve used Devolo in the past, never had problems with it. But it has been at least 5 years since I don’t use them anymore.
(long story short: solar panel convertor practically killed the powerline signal so had separate cat6 cable installed between the points where I used powerline before)
RouterOS in the powerline is the main difference from the other.
The newer, as replacements “Power Line Pro”, do not have an AP version (but will connect and power a hAP ac2 via PoE).
PWR Line Pro themselves have no RouterOS and cannot be managed or monitored.
hAP Lite comes closest if you can find that special USB power supply/line adaptor PL6400 or PL7400
Thanks for your considerations and advice.
I think I will turn my attention to Tp-Link products, especially for the variety of Powerline products and the update of their software.
