Used Remote Fixer to get my fire remote sorted and then found this site. Small world! Great work on both sites Smiggy
Just discovered Smiggy World and I already love it. The Osborne One article was fascinating, never heard of that machine before.
Stumbled across this site looking for ZigBee protocol info. The deep dive pages are incredibly thorough. Well done!
