Re: Setup wireless adapter with Rpi 3 b+

One way is to check your router's active associated MAC addresses vs. MAC addresses assigned to your interfaces.
Assuming nothing is connected to the ethernet port, if you disable the onboard wifi (per above) then your USB adapter is the point of WIFI connection.

Re: Complete beginner - Garage Door Dedection

IMO, a 3B+ is overkill, if it's only task is to monitor the garage door. A Pi0WH (with headers installed, so no soldering) will suffice. I monitor my entry doors with Pi0Ws + Pi Cameras + Pikrellcam. Works great. Your use case will probably use much less CPU and memory than mine. Are you doing this...

Re: PiKrellCam: motion vector detect + OSD web interface

I had a go at adding the new AWB 'greyworld' parameter to Pikrellcam for V2 NoIR cameras (see sticky at top of camera forum by jamesh). It's rather trivial :) As of this writing, you will need to run rpi-update to get the newest firmware. That will change soon, I assume. In ~/pikrellcam/src/config.c...

Re: Anyone in the US need an official Pi4 UK power supply?

Thanks for the suggestion. I considered that, but I'm rather anal (can I say that?) about reliable power. It would cost about $8 to get an adapter I would be comfy with.
Should I be so lucky to get my hands on a 4B4GB I'll buy a US version (locally :D ) for about the same price.
So the offer stands.

I've been dealing with a similar (if not identical) issue with 4kp60. My monitor is a Samsung U28E590. Samsung says HDMI2 can push 4kp60. I could not get 4kp60 from either my Pi42M (config.txt was correct) or my Windows 10 desktop, regardless of HDMI port. I switched my Win10 box to 2560x1440 @ 60Hz...
