Sounds like a decent set up you have there, and just read the reviews about the Schitt Fulla (what a name!!) and did’nt realise it was that good, especially for the costs involved.
Now you’ve made things really difficult…
Looks like maybe a bit more reading needs doing, but have to say, the now working M2P, just gets better and better and better.
Good luck with your Pi and thanks again all
