How about this:
- instead of $300 for an AP One AX Lite, spend $180 for an AP One Mini. Why? cheaper, and has lower power usage – I’ve measured my AP One Minis at about 5 Watts at idle. This should be lower than the AX
- run PoE and find an inexpensive 1 port 12V PoE injector, which you can get for under $50, as the Mini supports PoE Type 1 rather than the AX which supports PoE+ Type 2
Note: I’m not sure if the AX requires Type 2 (PoE+) or simply supports it, but in any case the Mini doesn’t.
