The voice commands are worse than touch screens and touch screens are worse than the optimal solution which is a tactile interface of switches/knobs. I stopped using Alexa voice controls for lights since its inconsistent and switched to a bluetooth switch, much more reliable have only had a few instances where it didn't work.

I don't do lots of home automation mostly because the automation isn't practical in a new build house that has switches in appropriate places. There are extremely rare circumstances where I want a light on/off in a room I'm not in. However, it would be a fun project to build a nice remote control with switches and knobs that you can program and have it talk to the home automation solution. To make it even more fun, I'm talking hard flip switches and volume like knobs, really tactile.
