I'm using a Neos SmartHome thing that Gadget John mentioned once. It was about £25 and plugs into a USB socket. The day and night image quality is remarkably good and I get alerts on my phone with a short video clip if there's motion or sound detected. I did disable the sound trigger though...
I did fit it in the end, and forgot I had started this thread! I also knocked together a talky video or what I did.
It might help someone one day, and it hasn't exploded yet :)
@ScoTTyBEEE have you watched any of the Project Amber videos? He also converted the same vehicle and probably has some knowledge of what you're going through.
If you've got somewhere off the road to work and aren't in a rush, take your time and enjoy the process of conversion. It's taken me a couple of years to get where I am today, as life and stuff just got in the way. The same result in the end though.
That's weird, as my network is 2Ghz and 5Ghz, so not sure which one they're connected on. I just ran Fing on my phone and they all appear. The mac vendor is saying "Espressif" for all of them.
I'm surprised you didn't get the teckin plugs working. I've got a couple of versions at home running on schedules (Smart Life app) and connected to google home for voice control. The round ones are especially nice as they don't cover the on/off switch of the wall socket, but they lack the energy...
You should find the use of red diesel etc are covered by section 5 of this document:

Have a good read of the 5.2 and 5.3 as it also answers questions asked in this thread.
