Answering my own question slightly here, but JDB Pi Engineer said this about Ethernet. "There are 3 ethernet PHY power states that you enter based on various conditions.

Re: RPi4 - Power Savings

Hi,
I realise for your case you require Ethernet, but does anyone know if it's possible/worthwhile turning off Ethernet to save power on a Pi4? I'm currently only using WiFi on my Pi4.

Re: RPi4 HEVC (h.265) playback not possible on Raspbian?

It does seem poor to tout capabilities knowing full-well they aren't ready yet. "Sure, you do get that Ferrari engine. But only one cylinder works." I am sure a lot of people feel that way when the official software doesn't allow you to use what the sales people say you get for your money. The prob...

The exact kernel version where the problem starts is 30th Jan 1526192.
So the Previous version 22nd Jan 993F475 is the last version that worked ok.

Re: pigpio vs. RPi.GPIO Hall sensor interrupt odd readings

Without knowing what your colours mean it's impossible to say. If I assume that RED and BLACK are the power input to your device, then yes that's fine. If the YELLOW is an open collector output from your device then again yes that is fine, though I believe the GPIO has its own pull up, but having an...

Re: pigpio vs. RPi.GPIO Hall sensor interrupt odd readings

I believe Joan is actually saying, if your output is open collector, you will not require a level shifter, because the open collector will only pull down to ground, or 'float' upto whatever the GPIO pull up is connected to, which is 3.3v
