Jim,
Nice that you have all this working off a single remote, yet it appears it is all new equipment, with electronic (not mechanical) switches, and fewer gadgets hooked up. I only have 4 HDMI plugs on my TV, yet I still need an a 5-port add-on HDMI switch box for my additional equipment, such as Fire TV stick, Chromecast, CD player, media player, HD radio box, DVD recorder, Echo Dot input. etc, etc. I have lots of gadgets connected to TV and stereo; way too much for a Harmony remote to fully control, and well, it is just not going to work for me. For those who can make it all work; go for it.
